hemalatha - you will need to post the algorithm/code that you are using to hide your image else it is difficult to guess at why you are observing dots in extracted image.

If you're building up the image a pixel at a time, I'd guess that there are some pixels that never got assigned for some reason. I'll have to wait until they release the Crystal Ball Toolbox to determine why.
