Abstract

The present embodiment discloses a video coding method and apparatus based on non-separable secondary transform adaptive to a primary transform kernel. In the present embodiment, an image decoding apparatus determines a primary inverse transform kernel in vertical and horizontal directions with respect to a transform block of the current block. The image decoding apparatus acquires dequantized secondary transform coefficients for the transform block. The image decoding apparatus determines a secondary inverse transform kernel of the transform block, on the basis of the size of the transform block, an intra prediction mode of the current block, and the primary inverse transform kernel. The image decoding apparatus generates primary transform coefficients by applying the secondary inverse transform kernel to the secondary transform coefficients, and then generates residual signals by applying the primary inverse transform kernel to the primary transform coefficients.

Abstract

Disclosed are a method and apparatus for adaptive coding of intra mode based on block location. In the present embodiment, an image decoding apparatus determines a type of the present block on the basis of the location of the present block and generates a most probable mode (MPM) list including MPM candidates.

The image decoding apparatus determines a representative mode from among the redundant prediction modes and reconfigures the MPM list by removing the redundant prediction modes excluding the determined representative mode. The image decoding apparatus decodes an MPM index of the present block from a bitstream and determines an intra prediction mode of the present block from the reconfigured MPM list by using the MPM index.

Abstract

Provided are an image encoding/decoding method and apparatus, a recording medium storing a bitstream, and a transmission method. The image decoding method comprises the steps of: generating a chrominance mode list of the current chrominance block, deriving a chrominance intra prediction mode of the current chrominance block on the basis of the chrominance mode list; and generating a prediction block of the current chrominance block on the basis of the chrominance intra prediction mode, wherein the chrominance mode list may comprise at least one of a default mode, a derivation-based chrominance mode, and a direct mode.

Abstract

Provided are an image encoding/decoding method and apparatus, a recording medium storing a bitstream, and a transmission method. The image decoding method may comprise the steps of: generating a first reference sample on the basis of a first reference region neighboring a current block; generating a second reference sample on the basis of a second reference region neighboring the current block; and performing intra prediction on the current block on the basis of the first reference sample and the second reference sample, wherein the first reference region may be a reconstructed region located at the left, top, and top left of the current block, and the second reference region may be a predicted region located at the right, bottom, and bottom right of the current block.
