Image Preparation For Steganography Capacity Estimation for Specific Image Genre

One of the important steps in steganography is to figure out how to embed a certain amount of message into cover medium (usually image). Different images may have different capacity and on top of that compression must also be considered. Embedding capacity is highly influenced by image complexity which reflects on quantized DCT histogram. For a lay person, the crucial factor is to know what kind of image is better suited for the amount of message to be hidden. Hence, the research aims at finding a relationship between image genre and steganographic capacity. The result shows that more objects in the image means more message to be hidden.
