Peculiarities of 3D Compression of Noisy Multichannel Images

Abstract

International audienceThe paper addresses practical aspects of multichannel images compression. Color and multichannel images are commonly characterized by high degree of component correlation. This property can be exploited in 3D-compression techniques for achieving high compression ratio. The main goal of this paper is to show that 3D-compression on basis of discrete cosine (DCT) transform offers some advantages in comparison to 2D application of DCT based coders
