Abstract: A method for processing an image includes obtaining an image to be processed; obtaining a depth feature map by inputting the image to be processed into a depth feature extraction network in an image recognition model, and obtaining a semantic segmentation feature map by inputting the image to be processed into a semantic feature extraction network of the image recognition model; obtaining a target depth feature map fused with semantic features and a target semantic segmentation feature map fused with depth features by inputting the depth feature map and the semantic segmentation feature map into a feature interaction network of the recognition model for fusion; and obtaining a depth estimation result and a semantic segmentation result by inputting the target depth feature map and the target semantic segmentation feature map into a corresponding output network in the recognition model.

Abstract: A computer-implemented stereo matching method includes: obtaining a first binocular image; inputting the first binocular image into an object model for a first operation to obtain a first initial disparity map and a first offset disparity map with respect to the first initial disparity map; and performing aggregation on the first initial disparity map and the first offset disparity map to obtain a first target disparity map of the first binocular image. The first initial disparity map is obtained through stereo matching on a second binocular image corresponding to the first binocular image, a size of the second binocular image is smaller than a size of the first binocular image, and the first offset disparity map is obtained through stereo matching on the first binocular image within a predetermined disparity offset range.

Abstract: Embodiments of the present disclosure provide an object tracking method and an apparatus. The method includes: obtaining multiple frames of first images shot by a first camera apparatus and a first shooting moment of each frame of the first images, where the first images include a first object; obtaining multiple frames of second images shot by a second camera apparatus and a second shooting moment of each frame of the second images, where the second images include a second object; obtaining a distance between the first camera apparatus and the second camera apparatus; and judging whether the first object and the second object are the same object according to the multiple frames of the first images, the first shooting moment of each frame of the first images, the multiple frames of the second images, the second shooting moment of each frame of the second images and the distance.
