Abstract
Procedimiento de codificación de al menos una imagen (ICj) recortada en bloques, que comprende, para un bloque corriente (Bu) a codificar, las etapas de: - predicción (C3) del bloque corriente con la ayuda de al menos un bloque predictor (BPópt), - determinación (C4) de un bloque residual de datos representativo de la diferencia entre el bloque predictor y el bloque corriente, - selección (C5), según un criterio de prestación de codificación predeterminado, de un par de operaciones matemáticas que comprenden una operación de permutación (OPm*) y una operación de transformación (OTn*) de entre respectivamente una pluralidad de operaciones de permutación (OP0, OP1,..., OPm,..., OPK-1), con 0<=m<=K-1 y 0<=m*K-1 y una pluralidad de operaciones de transformación (OT0, OT1,..., OTn,..., OTL-1), con 0<=n<=L-1 y 0<=n*<=L- 1, - aplicación (C6) de la operación de permutación (OPm*) de dicho par seleccionado a los datos del bloque residual determinado, - aplicación (C7) de la operación de transformación (OTn*) de dicho par seleccionado a los datos permutados, - codificación (C9) de los datos procedentes de dicha operación de transformación aplicada.
