Embodiment
[0028] A kind of specific embodiment of the present invention is, a kind of high-precision palmprint recognition algorithm based on independent matching score layer fusion, comprises the following steps:
[0029] a. Palmprint image preprocessing based on mobile subtraction method: cut out the palmprint image including two corner points between the middle finger and index finger, ring finger and little finger from the collected palmprint image, and then cut out the palmprint image Carry out median filtering and binarization processing; translate the binarized palmprint image forward, upward, and downward by 30 pixels, and fill the rear, lower, and upper parts of the image that were vacated after the translation with values If the pixel is 0, three shifted images are obtained; the three shifted images are subtracted from the binarized palmprint image respectively, so that the pixel value less than or equal to 0 is zero, and the value of the remaining pixels is 255 , to get three...
