detect_data_power.m Detects if the given image has data hidden in it with the zeros hiding method hidden_zeros_read.m Reads data hidden by zeros hiding method from an image image_hist.m Creates histogram of DCT coefficients image_stat.m Determines the threshold value for zero hiding detection invimageproc.m Takes tiled matrix and converts to image matrix jvector.m Traverses 8x8 block using the zig-zag pattern mat2DCEB.m Compresses image and returns tiled matrix readdata.m Reads in binary data from a file secread.m Reads in data hidden by bit-o-steg from an image signed_mat2DCEB.m Modified compressor used in zeros hiding std_stegcompress.m Groups zeros together and saves image stegcompress.m Takes a compressed image and hides data in it using bit-o-steg writedata.m Writes binary data to a file
