Image Formats
Image Formats Ioannis Rekleitis Many different file formats • JPEG/JFIF • Exif • JPEG 2000 • BMP • GIF • WebP • PNG • HDR raster formats • TIFF • HEIF • PPM, PGM, PBM, • BAT and PNM • BPG CSCE 590: Introduction to Image Processing https://en.wikipedia.org/wiki/Image_file_formats 2 Many different file formats • JPEG/JFIF (Joint Photographic Experts Group) is a lossy compression method; JPEG- compressed images are usually stored in the JFIF (JPEG File Interchange Format) >ile format. The JPEG/JFIF >ilename extension is JPG or JPEG. Nearly every digital camera can save images in the JPEG/JFIF format, which supports eight-bit grayscale images and 24-bit color images (eight bits each for red, green, and blue). JPEG applies lossy compression to images, which can result in a signi>icant reduction of the >ile size. Applications can determine the degree of compression to apply, and the amount of compression affects the visual quality of the result. When not too great, the compression does not noticeably affect or detract from the image's quality, but JPEG iles suffer generational degradation when repeatedly edited and saved. (JPEG also provides lossless image storage, but the lossless version is not widely supported.) • JPEG 2000 is a compression standard enabling both lossless and lossy storage. The compression methods used are different from the ones in standard JFIF/JPEG; they improve quality and compression ratios, but also require more computational power to process. JPEG 2000 also adds features that are missing in JPEG. It is not nearly as common as JPEG, but it is used currently in professional movie editing and distribution (some digital cinemas, for example, use JPEG 2000 for individual movie frames).

Developing New Afm Imaging Technique and Software for Dna Mismatch Repair
DEVELOPING NEW AFM IMAGING TECHNIQUE AND SOFTWARE FOR DNA MISMATCH REPAIR Zimeng Li A dissertation submitted to the faulty at the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Physics and Astronomy. Chapel Hill 2019 Approved by: Dorothy Erie Tom Clegg Richard Superfine Wu Yue Tom Kunkel Paul Modrich ©2019 Zimeng Li ALL RIGHTS RESERVED ii ABSTRACT Zimeng Li: Developing New AFM Imaging Technique and Software for DNA Mismatch Repair (Under the direction of Dorothy Erie) Atomic Force Microscopy (AFM) is a powerful technique to study the assembly and function of multiprotein-DNA complexes, such as the MutS-MutL-DNA complex in DNA mismatch repair. As a high-resolution, single-molecule imaging technique, AFM has the advantage of directly visualizing individual protein-DNA complexes in their native conformations, but it has two severe limitations. First, it is unable to resolve the location of the DNA inside the protein. Second, it lacks a comprehensive software that is tailored for single- molecule studies and high-throughput analyses. To tackle these issues, we developed DREEM (Dual-Resonance-frequency-Enhanced Electrostatic Force Microscopy). DREEM is a new AFM imaging method that is capable of resolving DNA path inside the protein-DNA complex. With DREEM, we can reveal the path of the DNA wrapping around histones in nucleosomes and the path of DNA through multiprotein mismatch repair complexes. We also developed Image Metrics, a full-featured AFM software package that excels in high-throughput shape analysis and single-molecule analysis.

A Robust Multilayer Image Steganography Method Based on a Randomized Lsb Algorithm
International Journal of Mechanical Engineering and Technology (IJMET) Volume 9, Issue 9, September 2018, pp. 272–284, Article ID: IJMET_09_09_031 Available online at https://iaeme.com/Home/issue/IJMET?Volume=9&Issue=9 ISSN Print: 0976-6340 and ISSN Online: 0976-6359 © IAEME Publication Scopus Indexed A ROBUST MULTILAYER IMAGE STEGANOGRAPHY METHOD BASED ON A RANDOMIZED LSB ALGORITHM Saad Almutairi Faculty of Computers and Information Technology, University of Tabuk, Tabuk City, Saudia Arabi Abdulgader Almutairi College of Sciences and arts in ArRass, Qassim University, Qassim, Kingdom of Saudi Arabia ABSTRACT Recently, the demand for the uses of the steganography techniques to exchange a hidden secret data throughout unsecure networks has increased substantially. Nonetheless, although there are many techniques and methods out there in steganography field, a further researches need to be conducted in order to come up with a new secure techniques and methods. Thus, our research proposes a new robust multilayer image steganography method called MITEGO method that is based on a randomized LSB algorithm to overcome the weaknesses of the previous related works in the field, and to provide more secure image steganography at different points. MITEGO method follows a set of rules to create a stego image object (stego file) to embed and extract a secret message based on two layers: Hardening Layer and Embed/Extract Layer. Subsequently, MiTEGOsoft software tool is developed based on MITEGO method. Finally, MITEGO method is evaluated based on experiments and analysis of corresponding results. The research calculated Peak Signal-to-Noise Ratio (PSNR) in decibel (dB) unit by using ImageMagick software tool for each generated stego file.
