Way to auto-remove the watermark when the original watermark image is available

Question

I have a lot of images that I created a while back, and all of them have the same watermark in the same location. I don't have the originals. I also have the original watermark image that is applied to all pictures.

I have never done this sort of thing before, are they any good approaches to this task?

Answer 1

Once you apply a watermark over an image, the original data of the image that gets covered by the watermark is gone forever. All you can do is use some blending and interpolation techniques to "guess" the original data. Having the original watermark helps you to identify it easier in your images. Maybe you can use the AForge .NET library to accomplish the task.
