Embodiment Construction
[0024] The method of the invention includes two parts: extraction of target features and classification and identification of targets. Among them, the feature extraction of the target adopts the deep learning method. By constructing a multi-hidden layer neural network, the sample features are transformed layer by layer, and the feature representation of the sample in the original space is transformed into a new feature space to learn more useful features. Then use this feature as the input feature of the multi-class SVM classifier to classify and identify the target, so as to finally improve the accuracy of classification or prediction. attached figure 1 The implementation block diagram of this algorithm is shown, and the specific steps are as follows:
[0025] (1) Preprocessing of the target image: extract n target images in the multi-camera domain and divide them into m labels; use the bicubic interpolation algorithm (bicubic interpolation) to uniformly adjust the image siz...
