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. WebBuilding a bag of visual words. Building a bag of visual words can be broken down into a three-step process: Step #1: Feature extraction. Step #2: Codebook construction. Step #3: Vector quantization. We will cover each of these steps in detail over the next few lessons, but for the time being, let’s perform a high-level overview of each step.
