Alternatively, the cosine similarity between each detection feature and each trajectory feature can be calculated to obtain the cosine similarity value between each detection feature and each trajectory feature, and the similarity generation value between each detection feature and each trajectory feature can be obtained according to the cosine similarity value between each detection feature and each trajectory feature,Each matrix element in the similarity cost matrix is constructed. In step s4062, feature fusion is performed for detection features and trajectory features, and trajectory features are updated based on feature fusion results.	cache/ajst-1304.pdf	txt/ajst-1304.txt
