Steganography for Regions with different data density

Description:

A well known method of stegano analysis is to search one colored area of the image for variations. In diffuse areas where every pixel has a different color than its neighbors, variations by hidden bits are hard to detect, but most pictures also contain areas with smooth colors. To escape from simple variations analysis, we'll hide our secret message only in these regions, and with adjusted "bit rates".
