Innovation:
General manufacturers only have regular shape ROI extraction or no regional division, resulting in irregular products, perforated screens, water drop screens and product edges due to ROI extraction, the region shielding position is too large resulting in increased missed detection, and sail sound algorithm software has various shapes of ROI extraction, can be effectively compatible with various shapes of products, reduce missed detection; It also has regional division for regional detection, different regions use different operators, especially special operators for edge or uneven brightness regions, which can effectively reduce over-detection!
