Most industrial vision system applications use a pretty controlled background, so intensity-based detection and segmentation works well and has few false positives. Pointing a camera towards the ceiling in an arbitrary high school gym or sports arena is not as controlled, so you often need to use other cues to differentiate the target from the background. These cues could include color, shape, size, etc.
