Image data compression using cubic convolution spline interpolation
A new cubic convolution spline Interpolation (CCSI) for both one-dimensional (1-D) and two-dimensional (2-D) signals is developed in order to subsample signal and image compression data. The CCSI yields a very accurate algorithm for smoothing. It is also shown that this new and fast smoothing filter fur CCSI can be used with the JPEG standard to design an improved JPEG encoder-decoder fur a high compression ratio.
