IMAGE DECODING DEVICE USING DIFFERENTIAL CODING
This abstract first appeared for US patent application 20250097448 titled 'IMAGE DECODING DEVICE USING DIFFERENTIAL CODING
Original Abstract Submitted
a video decoding method is configured to reconstruct a current block that is encoded using an intra prediction. the method includes decoding, from a bitstream, direction information indicating a direction of differential coding applied to a residual block of the current block, generating the residual block from residual signals by reconstructing and using the information on the residual signals from the bitstream and using the direction information, inversely quantizing the modified residual block, generating a prediction block for the current block through intra prediction, and reconstructing the current block by adding the prediction block and the inverse quantized residual block.
