Abstract

The present embodiment discloses a video coding method and apparatus using illumination compensation in geometric partitioning mode-based prediction. In the present embodiment, an image decoding apparatus decodes a GPM index and a candidate index, configures a GPM candidate list, and partitions the current block into two partitioned blocks according to the GPM index. The image decoding apparatus derives, from the GPM candidate list by using the candidate index, motion information regarding an inter-partitioned block that uses motion compensation and generates a reference block of the inter-partitioned block by using the motion information. After acquiring LIC parameters defining the linear relationship between the reference block, and the inter-partitioned block to which LIC has been applied, the image decoding apparatus generates a final prediction block of the inter-partitioned block by applying LIC to the reference block of the inter-partitioned block on the basis of the LIC parameters. The image decoding apparatus generates final prediction signals of the current block on the basis of the final prediction block of the inter-partitioned block.

Abstract

The present embodiment discloses a method and apparatus for video coding using local illumination compensation in affine model-based prediction. In the present embodiment, an image decoding apparatus generates motion vectors of sub-blocks by using the form of an affine model and control point motion vectors. The image decoding apparatus generates a reference block of the current block by deriving sub-reference blocks of the sub-blocks by using the motion vectors. When adjacent reference pixels of the current block are available, the image decoding apparatus selects locations of adjacent reference pixels of each sub-reference block for upper sub-reference blocks and left sub-reference blocks of the reference block. When adjacent reference pixels of the reference block are available at the selected locations, the image decoding apparatus derives a linear relation between the adjacent reference pixels of the current block and the adjacent reference pixels of the reference block, and applies local illumination compensation on the reference block by using the linear relation to generate a prediction block of the current block.

Abstract

The present embodiment provides a video coding method and device using local illumination compensation-based prediction in a geometric partitioning mode. In the present embodiment, an image decoding device decodes a geometric partitioning mode index, and partitions a current block into partitioned blocks according to the geometric partitioning mode index. The image decoding device generates reference blocks of the partitioned blocks by using motion information, and generates a prediction block of the current block by blending the reference blocks. When neighboring reference pixels of the current block are available and all or some of neighboring reference pixels of each reference block are available, the image decoding device generates neighboring reference pixels of a blended prediction block by blending the neighboring reference pixels of the reference blocks, and derives parameters of a linear relational expression between the neighboring reference pixels of the current block and the neighboring reference pixels of the blended prediction block. The image decoding device generates a final prediction block of the current block by applying local illumination compensation to the blended prediction block by using the parameters of the linear relational expression.

Abstract

The present embodiment discloses a video coding method and device for selecting a transform kernel and an inverse transform kernel according to prediction mode. An image decoding device of the present embodiment acquires inverse-quantized transform coefficients for a transform block of the current block, and decodes non-separable transform information. Here, the non-separable transform information indicates whether non-separable inverse transform is applied, the non-separable inverse transform representing non-separable primary inverse transform or non-separable secondary inverse transform. If the non-separable inverse transform is performed according to the non-separable transform information, the image decoding device derives an intra prediction mode of the transform block according to a prediction mode of the current block. On the basis of the intra prediction mode and the size of the transform block, the image decoding device determines a non-separable inverse transform kernel corresponding to a non-separable primary inverse transform kernel or a non-separable secondary inverse transform kernel.

The image decoding device generates a motion vector of a subblock by using the control point motion vectors of the current block and acquires a geometric model parameter of the subblock. The image decoding device generates a reference block from a reference picture by using the motion vector of the subblock, and calculates positions of reference pixels in the reference block on the basis of the geometric model parameter. The image decoding device applies an interpolation filter to the reference pixels to generate prediction values of the subblock, thereby generating a prediction block of the current block.

Abstract

The present embodiment provides a video coding method and device using template matching-based inter prediction. In the present embodiment, an image decoding device decodes a merge index of a current block, and generates a motion vector candidate list including a preconfigured number of motion vector candidates. The image decoding device performs initial motion correction on the motion vector candidates, and rearranges the motion vector candidates. The image decoding device selects motion information of the current block from the motion vector candidates by using the merge index, and then generates a prediction block of the current block by using the selected motion information. In a case of using template matching when performing the initial motion correction or rearranging the motion vector candidates, the image decoding device applies filtering to a block division boundary within a template area of the current block.

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

The present invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.

Abstract

The present embodiment discloses a video coding method and device using template-based prediction. In the present embodiment, a video decoding device decodes a distance index (adjacent_idx) indicating a distance between a current block and a template area. The video decoding device identifies the template area on the basis of the distance between the current block and the template area and a shape of the template area. The video decoding device searches for, using the template area, an optimal template in a search area on the basis of template matching, and then generates a prediction block of the current block from a reference block corresponding to the optimal template.

Abstract

The present embodiment provides a video coding method and device using luma component-based chroma component prediction. In the present embodiment, an image decoding device derives a corresponding luma block of a current chroma block on the basis of a color format. The image decoding device derives a luma component pre-restored area for the corresponding luma block and a chroma-component pre-restored area for the current chroma block on the basis of a block segment structure of the luma component and the chroma component and prediction information of the corresponding luma block. The image decoding device performs modeling of a relationship between samples within the luma component pre-restored area and samples within the chroma component pre-restored area, and then generates a predicted block of the current chroma block from samples of the corresponding luma block by using the modeled relationship.
