Abstract: The present disclosure provides an answer evaluation method, an answer evaluation system, an electronic device, and a medium. The method comprises: acquiring an answer image, for a test paper answered by a use; classifying the answer image based on a pre-trained test question classification model, so as to obtain an objective question answer area and a subjective question answer area; identifying at least one objective question in the objective question answer area and an objective question answers for each of the at least one objective question; identifying at least one subjective question in the subjective question answer area and a subjective question answers for each of the at least one subjective question; and determining a total score value of the test paper based on the objective question, the objective question answer, the subjective question and the subjective question answer.

Abstract: Embodiments of the present invention disclose method and apparatus for processing a depth image. The method comprises: obtaining the depth image and a captured image corresponding to the depth image; segmenting the depth image to obtain a plurality of segmentation units; calculating a corresponding depth reference value for each segmentation unit; determining a standard range of depth value for the each segmentation unit based on the corresponding depth reference value; and adjusting a depth value of each pixel of the depth image to the standard range of depth value corresponding to the segmentation unit in which the each pixel is located. The method and the apparatus of embodiments of the present invention can improve the quality of the depth image and cause the depth image to be easily identified.
