- Sound Steganography - Images hidden in spectrogram of music
- License: Freeware
- Price: 0.00


Program converts image file (square shape, maximum 120x120 pixels) into music file (*.wav, noise). You can watch the hidden image in spectrogram of music - process called sound steganography. This is first version of project with very slow computations. Currently working on more advanced and optimized version. project by Katarzyna Zarnowiec and Frederico Contente

This project is more optimal and advanced version of project http://www.mathworks.com/matlabcentral/fil...rogram-of-music Sound steganography Project Program converting pictures into music Components: * image_to_wav.m - main script with program, if you want to make changes with parameters of conversion/plotting, you can change them only in this file Algorithm based on program written in Perl, published on website http://www.ohmpie.com/imageEncode * gen_sin - function, computing wave * spectro - function, plotting spectrogram Modified algorithm Spectrogram (Short-time FT log magnitude)by Sean Fulop Published on http://www.mathworks.com/matlabcentral/fileexchange/1553 In program, change the name of the picture and music_file which you are reading, and name of the file into which these data are written. Picture shouldn't be very big
