- Abstract:
-
The paper presents a novel approach for generating defect sample images using point set matching, which addresses the challenges posed by small-sample in industrial defect detection. These challenges arise due to low defective rates of products, rapid iterative updating of products, limited coverage of defect types, and difficulty in obtaining high-quality labeled defect samples. The proposed method transforms defects from a multifeature perspective and applies a single-sample expansion technique to generate defect images with diverse characteristics. This method solves the problem of the difficult generation of a high-quality defect image by deep learning under small-sample conditions. Through image evaluation and experimental verification, this method can produce images with superior visual effects and can effectively improve defect segmentation and detection. This method can be applied to the training process of the deep learning model with few samples for sample expansion and improvement of the training effect.
