Image hiding and mining based on the subsection Zadeh-x transform

Zadeh-x transform algorithm is one of the important technologies in lower layer image mining. But during our experiments, we found that the mining with Zadeh-x transform will be failure in images whose gray span is large and gray levels are more than 5. So we have put forward an improved algorithm which we defined as subsection Zadeh-x transform in this paper. We separate the target from the background using the gray spectrum of the image. The new arithmetic processes the goal information only so the gray levels we have to deal with will be greatly reduced. We have realized lower layer image hiding and mining based on the subsection Zadeh-x transform using VC++. The results show that the subsection Zadeh-X transform is more effective in lower layer image hiding and mining.
