• Introduction of Number-Theoretic Transforms for Lossless Image Coding

抄録

Orthogonal transforms such as the KLT, DCT, etc. are widely used in image data compression. The major virture of such transforms is energy compaction in the transform domain. Recently promising results have been reported in the use of orthogonal transforms in lossless coding, where special attention has been paid to possible arithmetic inaccuracies arising from finite register length. A more fundamental solution to the problem is the use of a finite integer ring. Orthogonal transforms over finite integer rings were investigated in efforts to efficiently compute convolution. In spite of their elegance and efficiency, they are in history due to their dynamic-range restrictions and the advent of VLSI-implemented floating-point arithmetic operations. In this paper we consider the use of transforms over rings of integers for possible image data compression, recalling them from the archive. The purpose of this paper is not to show any conclusive evidence but possibilities.
