Method according to block size

A high frequency directional pass band from of the contourlet transform is selected for data embedding. Image features like Peak Signal to Noise Ratio (PSNR). The proposed method show that we could successfully embed data in cover_images and extract it with the average embedding capacity of (1/16) bits per pixel without any error. High capacity can be achieved using this method according to block size.
