Abstract
Official abstract text for this publication.
The present disclosure provides a method 1200 of decoding a transform block in an image frame from a bitstream. The method comprises decoding a single truncated unary binarisation from the bitstream, the single truncated unary binarisation being used for a horizontal transform and a vertical transform of a transform block of the image frame. The method then determines a type of the horizontal and vertical transform based on the decoded single truncated unary binarisation and decodes the transform block in the image frame by applying the determined type of horizontal and vertical transform to the transform block of the image.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of decoding a transform block in an image from a bitstream, the method comprising: decoding at least a single truncated unary codeword from the bitstream by using arithmetic decoding; and determining, for the transform block, a horizontal transform type by using the decoded single truncated unary codeword and a vertical transform type by using the decoded single truncated unary codeword, wherein, by using the decoded single truncated unary…
