    Abstract: A method for reconstructing an HDR image includes: acquiring a plurality of original images with same photographing scene and different exposure degrees; screening out a reference image from the plurality of original images, performing feature alignment processing on remaining original images according to the reference image, and obtaining displacement images of the remaining original images; determining an enhanced image according to the reference image and the displacement images of the remaining original images, wherein the enhanced image is obtained by performing image enhancement processing on a fused image after a down-sampling operation, and the fused image is obtained by performing feature fusion on the reference image and the displacement images of the remaining original images; and reconstructing the HDR images corresponding to the plurality of original images according to the enhanced images.

    Abstract: A video frame interpolation processing method and apparatus thereof, and a non-transitory readable storage medium. The method includes: (S101) acquiring a target video; (S102) acquiring a first frame number set, based on the target video; (S103) acquiring at least one speech fragment of a target audio; (S104) acquiring a second frame number set, based on the at least one speech fragment of the target audio and the target video; (S105) performing frame interpolation on the target video, based on the first frame number set and the second frame number set. The target video includes a plurality of video frames, each of the plurality of video frames has a corresponding frame number, and frame numbers of the plurality of video frames increase progressively in time order. The first frame number set includes at least one first frame number, and each of the at least one first frame number corresponds to a video frame with picture switch. The target audio corresponds to the target video in time domain. The second frame number set includes at least one second frame number, and each of the at least one second frame number corresponds to a video frame with subtitle switch, so as to avoid the deformation problem caused by picture switch in frame interpolation processing.
