Title (EN) METHOD AND DEVICE FOR PERFORMING TRANSFORMATION USING ROW-COLUMN TRANSFORMS
(FR) PROCÉDÉ ET DISPOSITIF POUR EFFECTUER UNE TRANSFORMATION À L'AIDE DE TRANSFORMÉES DE RANGÉE-COLONNE
(KO) 행 -열 변환 (ROW- COLUMN TRANSFORM)을 이용하여 변환을 수행하는 방법 및 장치
Abstract:
(EN) The present invention provides a method for performing transformation, the method comprising the steps of: deriving a row transform set, a column transform set, and a permutation matrix on the basis of a given transform matrix (H) and error tolerance parameters; obtaining row-column transform (RCT) coefficients on the basis of the row transform set, the column transform set, and the permutation matrix; and performing quantization and entropy encoding on the RCT coefficients, wherein the permutation matrix represents a matrix obtained by substituting a row of an identity matrix.
(FR) La présente invention concerne un procédé pour effectuer une transformation, le procédé comprenant les étapes consistant à : dériver un ensemble de transformées de rangée, un ensemble de transformées de colonne, et une matrice de permutation, sur la base d'une matrice de transformation donnée (H) et de paramètres de tolérance aux erreurs; obtenir des coefficients de transformées de rangée-colonne (RCT) sur la base de l'ensemble de transformées de rangée, de l'ensemble de transformées de colonne et de la matrice de permutation; et effectuer la quantification et le codage entropique sur les coefficients RCT, la matrice de permutation représentant une matrice obtenue par substitution d'une rangée d'une matrice d'identité.
(KO) 본 발명은, 변환을 수행하는 방법에 있어서, 주어진 변환 행렬 (H) 및 에러 공치" 파라미터 (error tolerance parameter)에 기초하여 행 변환 셋 ( row transform set ), 열 변환 셋 ( column transform set ) 및 치환 행렬 (permutation matrix)을 유도하는 단계; 상기 행 변환 셋, 상기 열 변환 셋 및 상기 치환 행렬에 기초하여 RCT (Row- Column Transform) 계수를 획득하는 단계; 및 상기 RCT 계수에 대해 양자화 및 엔트로피 인코딩을 수행하는 단계를 포함하되, 상기 치환 행렬은 단위 행렬 ( identity matrix)의 행 ( row)을 치환함으로써 획득되는 행렬을 나타내는 것을 특징으로 하는 방법을 제공한다.
