At the same time, due to the weak correlation of some residual blocks, if the conversion process is skipped and quantized directly, the coding efficiency will be improved, but this method needs to be coded and transformed for each coding unit (CU for short). Flag bit to indicate whether to skip the transformation process, thus affecting coding efficiency

The embodiment of the invention provides a video decoding method and device, a computer readable medium and electronic equipment. The video decoding method comprises the following steps of performing entropy decoding processing on a coding block of a video image frame to obtain a quantization coefficient block of residual data corresponding to the coding block, if it is determined that whether the inverse transformation processing process needs to be skipped or not according to the quantization coefficients in the quantization coefficient block, counting the quantization coefficients in a specified area in the quantization coefficient block, and acquiring a quantization coefficient statistical value, and determining whether to skip the inverse transformation processing process or not according to the quantization coefficient statistical value. According to the technical scheme of the embodiment of the invention, the video coding efficiency can be effectively improved.
Description
technical field [0001] The present application relates to the field of computer and communication technologies, and in particular, to a video decoding method, device, computer-readable medium, and electronic equipment. Background technique [0002] During the video encoding process, the encoding end usually needs to perform transformation, quantization and entropy encoding on the residual data between the original video data and the predicted video data, and then send it to the decoding end. Due to the diversity of residual data, a single DCT (Discrete Cosine Transform, Discrete Cosine Transform) transformation kernel cannot adapt to all residual characteristics. Therefore, for a residual block, it may be necessary to select multiple DCT transformation kernels as a transformation matrix combination. At the same time, due to the weak correlation of some residual blocks, if the conversion process is skipped and quantized directly, the coding efficiency will be improved, but th...
