Blind Source Separation of image sources

The case of more sensors than sources

More sources than sensors (M < N)

As this case constitutes an under-determined problem we have proposed an image encryption scheme on the basis of blind source separation (Fig. 9).

See the paper on hiding images in other "carrier" images presented at ICPR 1996.

Correlated image sources

It can be observed that natural images, are similar to nonstationary signals and they usually are cross-correlated.

See the specifics of image separation in a paper presented at EUSIPCO 1996.
