Image Based Search Engine.
Utilising Technical algorithms, such as contour based image recognition, object based recognition, etc. A Search Engine could be developed that would support picture input (whether a frame of video or still image) so that people could search images, based on an image input…
This could be useful for a whole range of applications. But I think the most profitable, could be just a plain search box function.
