specific Embodiment approach
[0064] In the first step, after the product image is collected, first use the "retraction scanning method" to scan to determine whether there is an intestinal object in the picture; if "there is no intestine in the picture", stop the subsequent scanning detection; if there is intestine in the picture, Then determine the approximate area where the intestinal body exists in the digital image.
[0065] See the specific process figure 2 Flowchart of the "retraction scan" of the region of the intestinal body shown. After the scanning calculation process, the coordinates of the four corners of the general area where the intestinal body is located can be obtained (see image 3 by (x 1 ,y 1 ), (x 2 ,y 1 ), (x 2 ,y 2 ) and (x 2 ,y 1 ) and other quadrilateral areas determined by four corner points).
[0066] In the second step, if there is "intestine in the picture" and the approximate area where the intestinal body exists has been determined, then scan and detect the two wra...
