There are many picture file formats to save images to, however much of the research in steganography is doneusing the JPEG format. JPEG is a very common and uses a relatively straightforward compression algorithm. Although there are severalJPEG compression scripts written for MATLAB, customizing them for our purposes and getting the output to work with the JPEG formatwould have shifted the focus of our project from steganography to implementing JPEG compression. Thus we decided to implement our owncustom image framework that would be similar to JPEG but much more straightforward.
