Abstract: A low-illuminance video processing method, a low-illuminance video processing device and a storage medium are disclosed. The method includes: acquiring a same number of preceding frame images and subsequent frame images corresponding to a current video frame of a low-illuminance video to obtain a frame image set corresponding to the current video frame, and performing traversal on the low-illuminance video to obtain frame image sets corresponding to all video frames; after performing image alignment on all frame images in the frame image sets corresponding to all video frames, inputting the frame image sets into a pre-trained low-illuminance image enhancement model to obtain enhanced frame images; and generating an enhanced video based on the enhanced frame images.

Abstract: The present application provides a video processing method, a device, and a storage medium. The method includes: coding and decoding an original video to obtain a mixed resolution video, where the mixed resolution video includes a first resolution frame and a second resolution frame each corresponding to a key frame, and a third resolution frame corresponding to a non-key frame, where the first resolution frame has a resolution higher than a resolution of the second resolution frame or a resolution of the third resolution frame; and amplifying, according to the first resolution frame and the second resolution frame, the third resolution frame corresponding to the non-key frame to output an amplified video, where the amplified video includes the first resolution frame corresponding to the key frame, and an amplified target frame corresponding to the non-key frame.
