IMAGE CODING/DECODING METHOD |
摘要 |
The invention relates to an image coding method, comprising the following steps for a domain corresponding to at least one portion of an image: a minimal triangular partition covering said domain is defined (21); a square matrix is associated with each of said source triangles by means of a first reversible transformation (22,23), whereby said matrix represents a specific source triangle (31); a second reversible decorrelation transformation is applied (24) to each square matrix, resulting in transformed matrixes. The inventive method can be used in isolation or as a supplement to another coding of the hierarchic type, for example. The invention also relates to corresponding decoding. |
