Embodiment Construction
[0019] The invention proposes an improved illumination preprocessing method of a human face image. By introducing the improved LBP operator and the Hamming distance error correction method into the illumination preprocessing method, the illumination preprocessing of the face image is carried out. The pretreatment process of the present invention is as figure 2 shown. The method is realized with the support of a computer equipped with digital image processing software, which includes the use of LBP algorithm to preprocess the image, including the collection, classification, encoding, storage and processing of digital image related information. The division of the intermediate data storage area and the operation of the data, call the supporting graphics processing software program, calculate the gray value M of each pixel of the graphics and the pixels in the surrounding neighborhood, and output the complete image according to the gray value M elephant. With the support of c...
