Abstract: The embodiments disclose a method and device for liveness detection and a computer-readable storage medium. The method includes that: a first image collected by a first image sensor of a binocular camera is acquired, and a second image collected by a second image sensor of the binocular camera is acquired: binocular matching processing is performed on the first image and the second image to obtain parallax information of the first image and the second image; and a Iiveness detection result is obtained according to the parallax information. By adopting the embodiments of the present disclosure, the accuracy of liveness detection can be improved.

Abstract: An image processing method, a device, an electronic apparatus, and a storage medium. The method comprises: acquiring a first target region image of a target object and a second target region image of the target object (101); processing the first target region image and the second target region image, and determining parallax between the first target region image and the second target region image (102); and obtaining, on the basis of displacement information between the first target region image and the second target region image and the parallax therebetween, a parallax prediction result between a first image and a second image (103). The method reduces the amount of computation for parallax prediction, thereby achieving faster parallax prediction.

Abstract: Embodiments of the present application disclose a binocular matching method, including: obtaining an image to be processed, where the image is a two-dimensional (2D) image including a left image and a right image; constructing a three-dimensional (3D) matching cost feature of the image by using extracted features of the left image and extracted features of the right image, where the 3D matching cost feature includes a group-wise cross-correlation feature, or includes a feature obtained by concatenating the group-wise cross-correlation feature and a connection feature; and determining the depth of the image by using the 3D matching cost feature. The embodiments of the present application also provide a binocular matching apparatus, a computer device, and a storage medium.
