The present disclosure relates to a video coding method, a video decoding method, a storage medium, and electronic equipment, and relates to the field of video technology. The video coding method filters the video frames in each GOP according to the size of the encoder GOP to remove the video frames. The high-frequency components in the medium are obtained to obtain a filtered video frame, and then the filtered video frame is encoded to obtain an encoded video. The video encoding method restores the high-frequency components of the decoded video frame by sharpening the decoded video frame decoded by the decoder, so that the sharpened image can be the same as the source video data. The present disclosure can effectively reduce the number of bits allocated to I frames by removing the high frequency components in video frames before encoding, and restore the high frequency components of video frames in the decoding stage, thereby increasing the number of bits allocated to P frames, which can reduce The number of Skip blocks, and effectively reduce the breathing effect that occurs during video encoding.
Description
technical field [0001] The present disclosure relates to the field of video technology, and in particular, to a video encoding method, a video decoding method, a storage medium, and an electronic device. Background technique [0002] Video coding is a technology that uses redundant information in the time domain and space domain of video to compress video. Now a hybrid coding scheme of temporal and spatial domain prediction is commonly used. The process restores the original video according to the encoded code stream. Since the encoding process is a lossy compression method, for the simple forward reference frame structure, the referenced frame can be divided into two types: I frame and P frame. For the prediction process of I frame, intra frame prediction can be used instead of reference frame. For other frames, P frames can refer to already coded P frames and I frames. Since during the encoding process, I frames will be allocated more bits, and it is necessary to set the...
