AI Technical Summary
Existing image encoding and decoding technologies lack efficient methods for deriving intra prediction modes and configuring reference pixels, particularly for color components, which affects the accuracy and performance of image processing systems.
An image encoding/decoding method and device that determines intra prediction modes based on state information of a target block, classifies prediction mode candidates into categories, and uses weighted or interpolation filters for reference pixels, allowing for selective modification of prediction blocks based on coding information.
Improves the accuracy and efficiency of intra prediction by effectively deriving intra prediction modes and utilizing selective reference pixel lines and filtering, enhancing coding performance.
