Abstract:
An image coding method and apparatus, and an image decoding method and apparatus are provided. In the coding method, a scanning manner parameter of a coding block is determined, and the scanning manner parameter may include at least one of: a region indication parameter used for determining a scanning region of the coding block and a scanning indication parameter used for determining a scanning order of pixels in a scanning region of the coding block; predicted values of part or all of pixels in the coding block are determined according to the scanning manner parameter; and the coding block is coded according to the predicted values, and a coding result is written into a bitstream.
