Algorithm scheme - Introduction of defect detection algorithm


· Defect detection algorithm: AI deep learning algorithms such as Image Classification, Object Detection, Semantic Segmentation and Instance Segmentation are adopted to process the processing.

· In the algorithm, the original image and photometric stereogram are used as inputs, and the detection and segmentation networks are used to achieve high detection of defects;

· Overkill for specific texture/grain of the product can also be optimized through model iteration;

· Rule algorithm: Based on large-scale statistical analysis of defect distribution, relevant rules can be formulated for different defect over-kill scenarios to reduce the over-kill rate;
