I am working and researching on Image watermarking/steganography and I'm stuck at a point and want to know which technique is better in image processing for data hiding.
Bit Plane Complexity Segmentation OR CDMA Spread spectrum.
Can some experts give their opinion on both techniques and which one is better and why? like advantages and disadvantages or comparison of both
Thanks a lot.
So, I just want to hide some text in a color or grayscale image using wavelet trasform.
I could use either bpcs or cdma spread spectrum technique. I want to know which one should go for and why.
This is for learning purpose and no particular application.
Thanks. Please let me know if u need any specific info.
