| Abstract: | A kind of embed algorithm is proposed based on image complexity classification while the satellite remote sensing image is the cover image. By exploiting the statistical features of image's spectrum,the algorithm splits the cover image and classifies these blocks by image complexity. The secret message is inserted into DCT middle coefficients of the selected blocks according to the classification result. Experimental results show that the hiding performance can be improved not only from the embed algorithm ... |
