Method and apparatus for processing images, device and storage medium

An apparatus for processing images, comprising:

• an original image and auxiliary information acquiring module configured to acquire an original image and auxiliary information of the original image;
• a feature map acquiring module configured to acquire an object feature map by inputting the original image into a main path of a first visual task processing model, and acquire an auxiliary feature map by inputting the auxiliary information into a branch path of the first visual task processing model;
• and
• an original image response map acquiring module configured to acquire a response map of the original image by fusing the object feature map and the auxiliary feature map and inputting fused object feature map and auxiliary feature map into the main path of the first visual task processing model;
• wherein in the case that the original image is a single image, the auxiliary information of the original image comprises a background image corresponding to the original image, and in the case that the original image is a video frame in a video, and the video frame is used as a current video frame which is not a first frame of the video, the auxiliary information of the original image comprises a previous video frame of the current video frame and a response map of the previous video frame,
• wherein the response map of the previous video frame is acquired in following manners:
• when the previous video frame belongs to one of first N video frames of a video, the response map of the previous video frame is a response map acquired by inputting the previous video frame into a second visual task processing model;
• and
• when the previous video frame does not belong to one of the first N video frames of the video, the response map of the previous video frame is a response map acquired by inputting the previous video frame into the first visual task processing model,
• wherein the second visual task processing model has higher prediction accuracy than the first visual task processing model, and N is a positive integer.
