Abstract
The present disclosure relates to systems and methods for image coding. The system may determine a predetermined region in a coding unit in an image, the predetermined region including a plurality of pixels. The system may determine whether a prediction angle of a prediction mode is larger than or equal to 0° and smaller than or equal to 90°. In response to determining that the prediction angle of the prediction mode is larger than or equal to 0° and smaller than or equal to 90°, for each of the plurality of pixels in the predetermined region, the system may determine a preliminary predicted value of the pixel based on at least one of one or more first reference lines associated with the coding unit along a prediction direction corresponding to the prediction angle. The one or more first reference lines may be along a first side or a second side of the coding unit and each of the one or more first reference lines may include a plurality of first reference pixels. The system may determine a compensation predicted value of the pixel based on at least one of one or more second reference lines associated with the coding unit along a compensation direction opposite to the prediction direction. The one or more second reference lines may be along a third side or a fourth side of the coding unit and each of the one or more second reference lines may include a plurality of second reference pixels. The system may determine a target predicted value of the pixel based on the preliminary predicted value and the compensation predicted value.
