(with scan lines from the original UNCOMPRESSED video) Raw image files contain minimally processed data (pixels) from the image sensor of either a digital camera, image scanner, or RAW motion picture film scanner. The file header of a RAW image typically contains information concerning the byte-ordering of the file, the camera sensor information and other image metadata like exposure setting, camera/ scanner/lens model, date (and, optionally, place) of shoot/ scan, format, size, number of colors, and other information needed to display the image. It is possible to save a RAW image file without a header (choose header=0). When the interleaved RAW image is saved without a header the computer doesn"t know the dimensions or any other crucial information that is needed to reconstruct the image out of the image data. <-- Photoshop .RAW, (h=0) I opened a 3 channel interleaved RAW document as a 1 channel (1 color) interleaved document. (reversible databend) When you open the image, softwares like for instance photoshop will ask you for this data, giving you the opportunity to “bend” (reversible) the image. At this moment, you will be able to choose the dimensions, the amount of channels and if the image will be displayed interleaved or non-interleaved. By entering another value then the original, the image will be displayed in a distorted way. <-- Photoshop .RAW, (h=0) interleaved, I opened a 3 channel interleaved document but entered a 3 slightly smaller value for the width. (reversible databend) In the case of a RAW image file, interleaving and non- interleaving refer to the order in which the RGB color values of every pixel are stored. In an interleaved Raw image, the data is stored in a RGBRGBRGB sequence. <-- Photoshop .RAW, (h=0) I opened the 3 channel interleaved RAW document as a 3 channel non- interleaved 8 bit document. (reversible databend) <-- Photoshop .RAW, (h=0) I opened a 3 channel interleaved RAW image in Microsoft Word (Convert to Text Only) and saved it. This technique reformats the image data into a Microsoft Word document, changing some of the values and adding / deleting some extra data.

(irreversible databend) BMP The BMP file format is uncompressed; every bit that indexes a bitmap pixel value is packed within a linear row, "upside-down" with respect to normal image raster scan order, starting in the lower right corner, advancing row by row from the bottom to the top. <-- Low quality Bitmap (.bmp) Random data replacement changed the values of the indexed colors in the color palette (irreversible databend) This is why, when you copy- paste some of the image data the lower part of the image will still be intact, while the upper part of the image only shifts (and sometimes discolors) In BMP files, and many other bitmap file formats the color palette consists of a block of bytes (a table or palette) listing the colors available for use in a particular indexed- color image. Each pixel in the image is described by a number of bits (1-32 bit color depth) that index a single color from the color palette, that is described right after the header.

  • Exploring the .BMP File Format
    Exploring the .BMP File Format Don Lancaster Synergetics, Box 809, Thatcher, AZ 85552 copyright c2003 as GuruGram #14 http://www.tinaja.com [email protected] (928) 428-4073 The .BMP image standard is used by Windows and elsewhere to represent graphics images in any of several different display and compression options. The .BMP advantages are that each pixel is usually independently available for any alteration or modification. And that repeated use does not normally degrade the image. Because lossy compression is not used. Its main disadvantage is that file sizes are usually horrendous compared to JPEG, fractal, GIF, or other lossy compression schemes. A comparison of popular image standards can be found here. I’ve long been using the .BMP format for my eBay and my other phototography, scanning, and post processing. I firmly believe that… All photography, scanning, and all image post-processing should always be done using .BMP or a similar non-lossy format. Only after all post-processing is complete should JPEG or another compressed distribution format be chosen. Some current examples of my .BMP work now do include the IMAGIMAG.PDF post-processing tutorial, the Bitmap Typewriterthat generates fully anti-aliased small fonts, the Aerial Photo Combiner, and similar utilities and tutorials found on our Fonts & Images, PostScript, and on our Acrobat library pages. A few projects of current interest involving .BMP files include true view camera swings and tilts for a digital camera, distortion correction, dodging & burning, preventing white punchthrough on knockouts, and emphasis vignetting.

  • Music 422 Project Report
    Music 422 Project Report Jatin Chowdhury, Arda Sahiner, and Abhipray Sahoo October 10, 2020 1 Introduction We present an audio coder that seeks to improve upon traditional coding methods by implementing block switching, spectral band replication, and gain-shape quantization. Block switching improves on coding of transient sounds. Spectral band replication exploits low sensitivity of human hearing towards high frequencies. It fills in any missing coded high frequency content with information from the low frequencies. We chose to do gain-shape quantization in order to explicitly code the energy of each band, preserving the perceptually important spectral envelope more accurately. 2 Implementation 2.1 Block Switching Block switching, as introduced by Edler [1], allows the audio coder to adaptively change the size of the block being coded. Modern audio coders typically encode frequency lines obtained using the Modified Discrete Cosine Transform (MDCT). Using longer blocks for the MDCT allows forbet- ter spectral resolution, while shorter blocks have better time resolution, due to the time-frequency trade-off known as the Fourier uncertainty principle [2]. Due to their poor time resolution, using long MDCT blocks for an audio coder can result in “pre-echo” when the coder encodes transient sounds. Block switching allows the coder to use long MDCT blocks for normal signals being encoded and use shorter blocks for transient parts of the signal. In our coder, we implement the block switching algorithm introduced in [1]. This algorithm consists of four types of block windows: long, short, start, and stop. Long and short block windows are simple sine windows, as defined in [3]: (( ) ) 1 π w[n] = sin n + (1) 2 N where N is the length of the block.

  • Automatic Detection of Perceived Ringing Regions in Compressed Images
    International Journal of Electronics and Communication Engineering. ISSN 0974-2166 Volume 4, Number 5 (2011), pp. 491-516 © International Research Publication House http://www.irphouse.com Automatic Detection of Perceived Ringing Regions in Compressed Images D. Minola Davids Research Scholar, Singhania University, Rajasthan, India Abstract An efficient approach toward a no-reference ringing metric intrinsically exists of two steps: first detecting regions in an image where ringing might occur, and second quantifying the ringing annoyance in these regions. This paper presents a novel approach toward the first step: the automatic detection of regions visually impaired by ringing artifacts in compressed images. It is a no- reference approach, taking into account the specific physical structure of ringing artifacts combined with properties of the human visual system (HVS). To maintain low complexity for real-time applications, the proposed approach adopts a perceptually relevant edge detector to capture regions in the image susceptible to ringing, and a simple yet efficient model of visual masking to determine ringing visibility. Index Terms: Luminance masking, per-ceptual edge, ringing artifact, texture masking. Introduction In current visual communication systems, the most essential task is to fit a large amount of visual information into the narrow bandwidth of transmission channels or into a limited storage space, while maintaining the best possible perceived quality for the viewer. A variety of compression algorithms, for example, such as JPEG[1] and MPEG/H.26xhave been widely adopted in image and video coding trying to achieve high compression efficiency at high quality. These lossy compression techniques, however, inevitably result in various coding artifacts, which by now are known and classified as blockiness, ringing, blur, etc.

  • (A/V Codecs) REDCODE RAW (.R3D) ARRIRAW
    What is a Codec? Codec is a portmanteau of either "Compressor-Decompressor" or "Coder-Decoder," which describes a device or program capable of performing transformations on a data stream or signal. Codecs encode a stream or signal for transmission, storage or encryption and decode it for viewing or editing. Codecs are often used in videoconferencing and streaming media solutions. A video codec converts analog video signals from a video camera into digital signals for transmission. It then converts the digital signals back to analog for display. An audio codec converts analog audio signals from a microphone into digital signals for transmission. It then converts the digital signals back to analog for playing. The raw encoded form of audio and video data is often called essence, to distinguish it from the metadata information that together make up the information content of the stream and any "wrapper" data that is then added to aid access to or improve the robustness of the stream. Most codecs are lossy, in order to get a reasonably small file size. There are lossless codecs as well, but for most purposes the almost imperceptible increase in quality is not worth the considerable increase in data size. The main exception is if the data will undergo more processing in the future, in which case the repeated lossy encoding would damage the eventual quality too much. Many multimedia data streams need to contain both audio and video data, and often some form of metadata that permits synchronization of the audio and video. Each of these three streams may be handled by different programs, processes, or hardware; but for the multimedia data stream to be useful in stored or transmitted form, they must be encapsulated together in a container format.

  • Understanding Image Formats and When to Use Them
    Understanding Image Formats And When to Use Them Are you familiar with the extensions after your images? There are so many image formats that it’s so easy to get confused! File extensions like .jpeg, .bmp, .gif, and more can be seen after an image’s file name. Most of us disregard it, thinking there is no significance regarding these image formats. These are all different and not cross‐ compatible. These image formats have their own pros and cons. They were created for specific, yet different purposes. What’s the difference, and when is each format appropriate to use? Every graphic you see online is an image file. Most everything you see printed on paper, plastic or a t‐shirt came from an image file. These files come in a variety of formats, and each is optimized for a specific use. Using the right type for the right job means your design will come out picture perfect and just how you intended. The wrong format could mean a bad print or a poor web image, a giant download or a missing graphic in an email Most image files fit into one of two general categories—raster files and vector files—and each category has its own specific uses. This breakdown isn’t perfect. For example, certain formats can actually contain elements of both types. But this is a good place to start when thinking about which format to use for your projects. Raster Images Raster images are made up of a set grid of dots called pixels where each pixel is assigned a color.

  • Dithering and Quantization of Audio and Image
    Dithering and Quantization of audio and image Maciej Lipiński - Ext 06135 1. Introduction This project is going to focus on issue of dithering. The main aim of assignment was to develop a program to quantize images and audio signals, which should add noise and to measure mean square errors, comparing the quality of the quantized images with and without noise. The program realizes fallowing: - quantize an image or audio signal using n levels (defined by the user); - measure the MSE (Mean Square Error) between the original and the quantized signals; - add uniform noise in [-d/2,d/2], where d is the quantization step size, using n levels; - quantify the signal (image or audio) after adding the noise, using n levels (user defined); - measure the MSE by comparing the noise-quantized signal with the original; - compare results. The program shows graphic result, presenting original image/audio, quantized image/audio and quantized with dither image/audio. It calculates and displays the values of MSE – mean square error. 2. DITHERING Dither is a form of noise, “erroneous” signal or data which is intentionally added to sample data for the purpose of minimizing quantization error. It is utilized in many different fields where digital processing is used, such as digital audio and images. The quantization and re-quantization of digital data yields error. If that error is repeating and correlated to the signal, the error that results is repeating. In some fields, especially where the receptor is sensitive to such artifacts, cyclical errors yield undesirable artifacts. In these fields dither is helpful to result in less determinable distortions.

  • Glitch Studies Manifesto
    [email protected]. Amsterdam/Cologne, 2009/2010 http://rosa-menkman.blogspot.com The dominant, continuing search for a noiseless channel has been, and will always be no more than a regrettable, ill-fated dogma. Even though the constant search for complete transparency brings newer, ‘better’ media, every one of these new and improved techniques will always have their own fingerprints of imperfection. While most people experience these fingerprints as negative (and sometimes even as accidents) I emphasize the positive consequences of these imperfections by showing the new opportunities they facilitate. In the beginning there was only noise. Then the artist moved from the grain of celluloid to the magnetic distortion and scanning lines of the cathode ray tube. he wandered the planes of phosphor burn-in, rubbed away dead pixels and now makes performance art based on the cracking of LCD screens. The elitist discourse of the upgrade is a dogma widely pursued by the naive victims of a persistent upgrade culture. The consumer only has to dial #1-800 to stay on top of the technological curve, the waves of both euphoria and disappointment. It has become normal that in the future the consumer will pay less for a device that can do more. The user has to realize that improving is nothing more than a proprietary protocol, a deluded consumer myth about progression towards a holy grail of perfection. Dispute the operating templates of creative practice by fighting genres and expectations! I feel stuck in the membranes of knowledge, governed by social conventions and acceptances. As an artist I strive to reposition these membranes; I do not feel locked into one medium or between contradictions like real vs.

I authorize the University of Waterloo to lend this thesis to other institutions or individuals for the purpose of scholarly research. I further authorize the University of Waterloo to reproduce this thesis by pho- tocopying or by other means, in total or in part, at the request of other institutions or individuals for the purpose of scholarly research. ii The University of Waterloo requires the signatures of all persons using or pho- tocopying this thesis. Please sign below, and give address and date. iii Abstract A detailed mathematical model is presented for the analysis of multibit quantizing systems. Dithering is examined as a means for eliminating signal-dependent quanti- zation errors, and subtractive and non-subtractive dithered systems are thoroughly explored within the established theoretical framework. Of primary interest are the statistical interdependences of signals in dithered systems and the spectral proper- ties of the total error produced by such systems. Regarding dithered systems, many topics of practical interest are explored. These include the use of spectrally shaped dithers, dither in noise-shaping systems, the efficient generation of multi-channel dithers, and the uses of discrete-valued dither signals. iv Acknowledgements I would like to thank my supervisor, Dr. Stanley P. Lipshitz, for giving me the opportunity to pursue this research and for the valuable guidance which he has provided throughout my time with the Audio Research Group.
