Abstract: In the detection and identification of network carbides defects in mold steels, algorithms based on image processing and machine learning are commonly used, which can achieve automation to a certain extent, while the identification accuracy still has limitations in cases where the number of network carbides is large and the morphology is complex. To address the limitations of low recognition rate mentioned above, an improved CAM-YOLOx-DeepSORT algorithm is proposed, which utilizes the CAM attention mechanism and combines with the YOLOx object detection algorithm and DeepSORT object tracking algorithm to realize automatic detection and identification of the network carbides in mold steels. The results show that the algorithm can efficiently and accurately detect network carbides,the detection accuracy reaches 99.1%, thus providing guidance for quality control of mold steels.
