Does software exist for following moving objects from frame to frame in video images? I'm looking for something that works by finding low-level features such as edges and corners and matches them from one frame to the next. I'm aware of "optical flow" calculation, but the usual numeric method for doing this is differentiation-oriented and too noise-sensitive to be useful on real-world images, I am told by someone who has tried it. So I'd like something that finds many low-level features and tries to match them up. The intended application is a vision system for a robot vehicle. But it is possible that techniques used for colorizing B/W films would be useful for this purpose. So I'd like to hear from people who know how colorizing is done. Software, algorithms, hardware, or indications of research activity would be useful. John Nagle Center for Design Research, Stanford
