【Abstract】 Studied on the quick search used in automobile license plate automatic recognition. Only one point was noted every other point in horizontal and one row was noted every other row in vertical to cut off large quantity of data in image and avoid the problem of bad real time. A buildup difference arithmetic was used in feature extraction of texture. And a new expression was deduced to implement the quick search by window.更多还原
