Abstract
An apparatus and a method of recognizing image feature pixels is related to the recognizing method including receiving an image having a plurality of pixels; subsequent filtering the pixels at least once by detecting the edge pixels of objects in the received image based on pixel values of the pixels, so as to obtain a plurality of candidate pixels; and performing multiple difference of Gaussian (DOG) blurring operations on the candidate pixels to find the candidate pixels having a relative extreme value as a plurality of feature pixels. Therefore, the processing time of recognizing image feature pixels may be reduced.
