Abstract
Embodiments of the present disclosure relate to the field of video coding and decoding, and provide a picture decoding method, a picture coding method, and corresponding apparatuses. According to an example of the picture decoding method, a quantization parameter (QP) value of at least one pixel point is determined for any at least one pixel point indicating one pixel point or a plurality of parallel dequantized pixel points in the current coding block, the QP values of at least two pixel points among pixel points in the current coding block being different. The at least one pixel point is then dequantized according to the QP value of the at least one pixel point. The QP value of each pixel point is determined for the coding block; therefore, each pixel point can be dequantized according to the QP value of each pixel point.
