WebIn computer vision, the bag-of-words model (BoW model) sometimes called bag-of-visual-words model [1] [2] can be applied to image classification or retrieval, by treating image features as words. In document classification, a bag of words is a sparse vector of occurrence counts of words; that is, a sparse histogram over the vocabulary. WebOct 29, 2024 · The SIFT feature described by the BoW model is also used to train the SVM classifier. A transferred model which regards the AlexNet as the feature extractor and SVM as the classifier is set as another reference. Our proposed method uses the pre-trained VGG network to learn the high-level feature contained in the defects.

The sub-pixel localization proceeds by fitting a Taylor expansion to fit a 3D quadratic surface (in x,y, and σ) to the local area to interpolate the maxima or minima.
