Improved moving target recognition algorithm based on block matching

Traditional block matching algorithms have many deficiencies in image feature extracting and image matching, the complex edge extraction and the matching principle based on gray scale make the processing speed and accuracy decrease. To make the identification process more quickly and accurately, a recognition algorithm of the improved block matching was proposed. The image feature was enhanced by Laplace operator to improve the feature information. The results show that the average computing time of feature enhancement of this algorithm is about 0.005 4 s for 320240 pixels picture in Matlab.
