Self-adaptive face search method and system, medium, equipment and terminal

The invention belongs to the technical field of image recognition, and discloses a self-adaptive face search method and system, a medium, equipment and a terminal.The self-adaptive face search method comprises the steps that a face search engine is initialized, and a face picture to be searched or added is uploaded; performing feature extraction on the face image by using a face feature extraction module; the face search engine receives scheduling of the face search module, searches and adds face feature vectors and returns results to the face search module. According to the face search method and system based on the decision tree, the face feature recognition and the vector search engine, the face feature points can be accurately recognized. According to the method, the feature difference between the faces is calculated through an algorithm, and assistance can be provided for object search and personnel identity authentication. According to the decision tree, the optimal index construction mode under differe
