Hi all,
I'm processing RGB images each color corresponding to an element and the value representing the intensity. Combining the RGB channels makes the feature I'm interested in really stand out. The human eye can barely miss the big red blob in the attached image. What I would like from matlab is to tell me whether such a red blob is present in an image. My problem is that I don't really now how to start with image processing. I have a couple of ideas like checking for a certain threshold values. Combining that with reducing the number of pixels in the images by averaging to avoid that a single pixel can result in a positive identification. However, I'm pretty sure a lot more people have done similar work and are a lot more experienced!
Any suggestions for me?
Cheers,
Rick
