I try to make app like ink hunter, make it to detect object but on live camera overlaped image blink cause every time i detect object again n again in every frame.I read lot about track object but not found any useful algorithm, cause once algorithm i confuse with other algorithm, i very confuse which method or algorithm should i use,Initially i detect hand written plus sign and get center point of ROI when plus detected, Now which algorithm should i use to track center point of rect and place image over there.
