Abstract: Aiming at the problems of traditional surface defect detection algorithms, such as low detection efficiency and it has difficulty to deal with complexity detection, a new attention mechanism algorithm is proposed by combining deep learning and attention mechanism technology. First, rethink profoundly the Convolutional Neural Networks (CNN) and Transformer architecture, and redesign the high-dimensional feature extraction module; secondly, improve the latest attention mechanism to capture global features. This algorithm can easily embed various CNN, improve the performance for image classification and surface defect detection. The accuracy of the ResNet network using this algorithm on the CIFAR-100 data set and the textile defect data set reaches 83.22% and 77.98% respectively, which is superior to the classical attention mechanism SE and the latest Fca and other methods.

Keywords: defect detection; attention mechanism; Convolutional Neural Network; image classification
