Abstract
The disclosure provides image encoding methods and apparatuses. One example encoding method includes: obtaining a one-dimensional sequence of quantized coefficients of an image; obtaining a run-length value sequence and a level value sequence based on the one-dimensional sequence of the quantized coefficients; obtaining an updated second distribution probability of each level value in the level value sequence based on the m first distribution probabilities, the n second distribution probabilities, and a preset mapping rule; and performing encoding based on the level value sequence and the updated second distribution probability of each level value in the level value sequence to obtain and output encoded image data.
