Embodiment Construction
[0021] Such as figure 1 and figure 2 As shown, a video tracking system based on temporal and spatial alignment of target features involved in this embodiment includes: a global feature extraction module, a target position prediction module, a target feature extraction module, and a target tracking module.
[0022] Such as image 3 As shown, the global feature extraction module includes: a feature extraction network and an adjacent frame similarity calculation unit, wherein: the feature extraction network generates the corresponding original frame and the feature map of the reference frame according to the original frame and the reference frame of the video to be tested , and its size after downsampling is (C, H, W). The adjacent frame similarity between the two feature maps calculated by the adjacent frame similarity calculation unit.
[0023] The similarity calculation of the adjacent frame feature map adopts the method of spatial correlation, that is, each pixel on the c...
