Abstract

In this paper, the cubic spline interpolation (CSI) is shown to be performed by a direct computation for the encoding and decoding processes of image coding. A pipeline structure can be used to implement this new CSI. Such a new CSI algorithm can be used along with the JPEG standard to obtain the new CSI-JPEG codec and while still maintaining good quality of the reconstructed image for higher compression ratios. In this paper, it is shown that this new CSI-JPEG codec makes possible a pipeline compression algorithm that is naturally suitable for hardware implementation.
