    A New Steganographic Method for Palette-Based Images

    IS&T's 1999 PICS Conference A New Steganographic Method for Palette-Based Images Jiri Fridrich Center for Intelligent Systems, SUNY Binghamton, Binghamton, New York Abstract messages. The gaps in human visual and audio systems can be used for information hiding. In the case of images, the In this paper, we present a new steganographic technique human eye is relatively insensitive to high frequencies. This for embedding messages in palette-based images, such as fact has been utilized in many steganographic algorithms, GIF files. The new technique embeds one message bit into which modify the least significant bits of gray levels in one pixel (its pointer to the palette). The pixels for message digital images or digital sound tracks. Additional bits of embedding are chosen randomly using a pseudo-random information can also be inserted into coefficients of image number generator seeded with a secret key. For each pixel transforms, such as discrete cosine transform, Fourier at which one message bit is to be embedded, the palette is transform, etc. Transform techniques are typically more searched for closest colors. The closest color with the same robust with respect to common image processing operations parity as the message bit is then used instead of the original and lossy compression. color. This has the advantage that both the overall change The steganographer’s job is to make the secretly hidden due to message embedding and the maximal change in information difficult to detect given the complete colors of pixels is smaller than in methods that perturb the knowledge of the algorithm used to embed the information least significant bit of indices to a luminance-sorted palette, except the secret embedding key.* This so called such as EZ Stego.1 Indeed, numerical experiments indicate Kerckhoff’s principle is the golden rule of cryptography and that the new technique introduces approximately four times is often accepted for steganography as well.
  • Understanding Image Formats and When to Use Them

    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.

Framebuffers: Indexed-Color • An indexed-color (8-bit or PseudoColor) framebuffer stores one byte per pixel (also: GIF image format) • This byte indexes into a color map: • How many colors can a pixel be? • Common on low-end displays (cell phones, PDAs, GameBoys) Framebuffers: Indexed Color Illustration of how an indexed palette works A 2-bit indexed-color image. The color of each pixel is represented by a number; each number corresponds to a color in the palette.

    Fourier Theory & Practice, Part II: Practice

    Fourier Theory & Practice, Part II: Practice Operating the HP 54600 Series Scope with Measurement/Storage Module By: Robert Witte Hewlett-Packard Co. Practice Adding the Measurement/ Storage module to the scope adds additional waveform math capability, including FFT. These functions appear in the softkey menu under the ± (math) key. There are two math functions available, F1 and F2. The FFT function is available on Function F2. Function F2 can use function F1 as an operand, allowing an FFT to be performed on the result of F1. By setting function F1 to Channel 1 - Channel 2, and setting F2 to the FFT of F1, the FFT of a differential measurement can be obtained. The Measure- ment/Storage Module operating manual provides a more detailed discussion of these math functions. The scope can display the time domain waveform and the frequency domain spectrum simultaneously or individually. Normally, the sample points are not connected. For best frequency domain display, the sample points should be connected with lines (vectors). This can be accomplished by turning off all (time domain) channels and turning on only the FFT function. Alternatively, the Vectors On/Off softkey (on the Display menu) can be turned On and the STOP key pressed. Either of these actions allow the frequency domain samples to be connected by vectors which causes the display to appear more like a spectrum analyzer. The vertical axis of the FFT display is logarithmic, displayed in dBV (decibels relative to 1 Volt RMS). dB V = 20 log (VRMS) Thus, a 1 Volt RMS sinewave (2.8 Volts peak-to-peak) will read 0 dBV on the FFT display.

    Getting Started

    _______________________________ Getting Started Version 3.0 Getting Started with PMView Pro Installation & Setup If you are reading this file, you have likely already been through the installation process of PMView Pro. This section is intended to guide you through any subsequent installations and further setup procedures necessary to ensure PMView Pro is working properly on your system. Starting PMView Pro Starting PMView Pro can be as easy as double-clicking any image file. You were given the option during installation to install a shortcut to the desktop and/or the Start Menu as well. On the Start Menu, you will also notice that you can access this file, the Online Help file and PMView itself. PMView Pro also includes potentially unlimited startup options when started using the combination of command line options and script files. You can learn more about command line options and script files from the included help file. File Associations A common issue that may arise at some point after the installation of PMView Pro is the loss of file associations. You will recall that during installation you were presented with a list of file formats to associate with PMView. Even if you selected all formats, other programs may adjust those settings during their installation. The easiest way to have PMView reclaim those associations is to run the PMView Pro installation file again. If you only need to reclaim one or several of those associations, you can do this through the Windows operating system settings. By opening Windows Explorer from the start menu and selection Tools->Folder Options, you will be able to access the system File Type settings.
