In this research, we use conventional RGB (Red, Green, Blue) images as input data. The conventional RGB image is demosaiced from raw image by using the color interpolation

T transforms S into a region R in the xy-plane called the image of S, consisting of the images of all points in S.... So we begin by finding the images of the sides

Corollary 13.3. For, if C is simple and lies in D, the function f is analytic at each point interior to and on C; so we apply the Cauchy-Goursat theorem directly. On the other hand,
