[0101] Several parameters are involved in the computer-aided diagnosis system for breast cancer based on mammography that the present invention proposes, and these parameters will be comprehensively adjusted and set to achieve the good performance of the overall system according to the data characteristics of specific processing. Parameters set by the present invention for processing data sets:
[0102] Step (2.1) utilizes the initial template size correlation parameter L=25 that two-dimensional hyperbolic secant (sech) function obtains;
[0103] Step (2.2) carries out binarization processing to the threshold T selected by the correlation image low = 0.5 × input mammography maximum gray level;
[0104] The threshold T selected in step (2.3) multi-scale analysis high = 0.6 × input mammography maximum gray level;
[0105] Step (3.1) takes the center of the region of interest as the endpoint, starts from the zero-degree angle, and draws R=64 rays outwards in the counterclockwi...
