Abstract

In this paper, it is shown that the enhancement of X-Ray and CT picture can be obtained by using Fast Polynomial Transform ( FPT) to implemention of 2-D circular convolution . A hidden modulo arithmetic of FPT with operating length 64 and a new design of simple 2-D Frequency Sampling Filter are presented. The filting convolution processing of X-Ray and CT picture is very helpful in efficiently diagnosing lung cancer and liver tubercular.
