The embodiment of the invention provides an image processing method, model and device, electronic equipment and a readable storage medium. The method comprises the following steps: acquiring a video stream about a target object; for each image frame in the video stream, determining a first weight of each image frame according to an association relationship between each image frame and each image frame in the video stream; fusing the image frames based on the first weight of each image frame; and based on a result after fusion, extracting to obtain a trajectory feature of the target object. According to the scheme, for each image frame in the video stream, the video stream is decoded; the first weight of the image frame is determined according to the incidence relation between the image frame and each image frame in the video stream; according to the method, the first weight of each image frame is calculated, the image frames are fused based on the first weight of each image frame, andthe track features of the target object are extracted based on the fused result, that is, during track feature extraction, the relationship between frames in the video stream is considered, so that abetter feature expression effect is obtained, and the processing effect is improved.
