Watermark Example

The following images show a watermark (which, in our applications, is ordinarily a gray-level image) and an example of an image overlaid with a scaled version of that watermark.

The merging of the two images is purposely done in a manner which preserves the accurate color of the image to be protected and which does not obtrude too obviously on the ability to study the image, yet which clearly indicates the source of the image.
