A hierarchical picture coding scheme

摘要

The coding of the picture information is an important field for study with a great variety of applications. In this paper we present a hierarchical scheme for coding of a reduced amount of picture information, by combining efficiently two hierarchical data structures. In particular, the pyramid data structure is used to generate the pyramid of the average intensities of a picture P(N, N). The regular decomposition method is applied on the above pyramid in order to reduce the picture information hierarchically. On the reduced picture information, an orthogonal transformation coding scheme is applied.
