Abstract
Official abstract text for this publication.
An apparatus and method for video encoding/decoding considering impulse signal are disclosed. The method for video encoding includes generating a predicted block from predicting a current block and subtracting the predicted block from the current block to generate an M×N residual block, and encoding an A×B residual block containing residual signals of an impulsive component in the M×N residual block to generate a bitstream. The apparatus and the method of the present disclosure improve coding efficiency by efficiently encoding or decoding the residual signals of the impulse component in encoding or decoding videos.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for video encoding, the method comprising: generating a predicted block by predicting a current block; generating an M×N residual block by subtracting the predicted block from the current block; when the M×N residual block includes no impulsive components having values larger than the predetermined value, setting all residual signals of the M×N residual block to zero; and when one or more of frequency coefficients generated through transfo…
