Will the bright pixel tracing function only work in darkness? Make your own movie with someone writing with a glow stick or flashlight, in normal bright- ness. Does the function still work? Do you need to use a different threshold value? Do you have to try a different approach to identify “bright” pixels (e.g., perhaps by comparing luminance a particular pixel to the pixels around it)?
What will be an ideal response?
Note: Whether the functil will still work will highly depend on the video. If the video is in a fairly dim still, a bright light may still stand out enough to work with this approach, or by slightly altering the threshold value in brightPixel. However, if the scene is too bright then it will take more effort to distinguish the bright pixels. The option suggested above will work, and can be accomplished by passing in the pixel to the left and right and
seeing if either of them are also bright.
