Effective steel surface defect classification with low computational cost is essential for online quality inspection. The challenge of this task is large intra-class differences and unclear inter-class distances shown in various surface defects. This paper proposes a novel feature extraction method based on Legendre multi-wavelet transform and Auto-Encoder network (LWT-AE) for effecti... https://www.markbroyard.com/limited-price-rusk-deepshine-6-66rr-pure-pigments-conditioning-cream-for-discount-hot-buy/
