VIDEO ENCODING METHOD AND DEVICE, AND VIDEO DECODING METHOD AND DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240380890 titled 'VIDEO ENCODING METHOD AND DEVICE, AND VIDEO DECODING METHOD AND DEVICE
The present disclosure pertains to apparatus and methods of image decoding and encoding. In one or more embodiments, an image decoding method involves determining the first sample value of an upper left reference sample of the current block. The method also includes sequentially searching for a searched reference sample of at least one reference line from a plurality of reference lines, excluding the upper left reference sample. Additionally, the method involves determining the second sample value of the remaining reference samples of the current block, except for the upper left reference sample. Intra prediction is performed on the current block to obtain a prediction block, followed by obtaining a residual block and a reconstruction block of the current block.
- Image decoding method involves determining sample values of reference samples.
