[0036] The technical solutions in the embodiments of the present invention will be described clearly and in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. The described embodiments are only some of the embodiments of the invention.
[0037] The technical scheme that the present invention solves the problems of the technologies described above is:
[0038] attached figure 1 It is a system structure block diagram of the present invention. It proceeds in the following steps:
[0039] Step 1. Use histogram equalization to perform histogram equalization on the R, G, and B channels of the input image respectively
[0040] Step 2, convert the RGB image preprocessed in step 1 into an HSV color model, then extract the target color information, and carry out preliminary segmentation in conjunction with 8 connected regions to obtain a region of interest (Region Of Interest, ROI)
[0041] Step 201, RGB image is converted into HS...
