object detection

[barneygumble742]

hello,

in blog detection (i think thats what its called), what is the name of the process where a video is turned from color to black and white so that detection would be simple?

in a video, i'm trying to red balls in a frame. this function would convert the red to white and everything else is black. i saw it online a while ago and now i forgot the terminology.

thanks,

If all the colors are being converted to a small set of colors, the term would probably be "thresholding" or maybe "contrast enhancement."
