<P>PROBLEM TO BE SOLVED: To extract change with time by obtaining difference in a respiration moving picture photographed during a plurality of respiration cycles that are separated with time. <P>SOLUTION: In S1, N respiration cycle images photographed in Heisei P year are inputted. In S2, a lug field binary image is extracted in the breast front images of respective images. In S3, lug field area S is calculated. In S4, lug field height is calculated. In the fluctuating waveform formation of the area and height of S5, a region is obtained to the N inputted images for graphing. In S6, it is certified whether each image is in an expiration mode or an inspiration mode. In S7, respective images are sorted for storing. Then, the same processing is made to N respiration cycle images in Heisei P+1 year. By an image analysis, a differential image is obtained for extracting the change with time for a reference image photographed in Heisei P year and a reference image photographed in Heisei P+1 for each mode. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
