Re: Image processing for vision tracking: blacka and white, or color?
Color takes three times the data, so black and white tends to take less memory and less time to process.
On the other hand, since we see in color, it is somewhat difficult for us to get our heads wrapped around the B&W image processing techniques. Also, if there is a uniquely colored entity in the photo, color will be an easy task whereas black and white cannot take that approach and must be based on shape, proximity, or other artifacts.
In many of the LV FRC vision examples, both color and BW are used. The color will often be used to identify potential areas, and those areas are further processed, often in B&W, in order to rank them or disqualify them.
