In this approach using the Poisson equation a guided vector field is created by employing source and target images within a selected region at the first step. Next the guided vector is used in generating the result image. Most of the existing techniques in the literature perform image editing without taking color information into account. However without utilizing color information image geometry cannot be created properly in some cases which may result in unsatisfactory results. Unlike the existing methods the proposed study utilizes all the information contained in each of the color channels in computing gradient norm and performing inpainting process. The test results show that the suggested technique generates satisfactory results in editing color images. Keywords Poisson equation guided interpolation editing color images inpainting color images calculation of gradient of color images seamless and mixed seamless image cloning arranging local illumination changes texture flattening covariant inpainting 1. Introduction Digital image processing operations are related with global changes including image correction filtering colorization or local changes in a selected region where altering processes take place. Commercial or artistic photomontages take the local changes in images into account. Along with the technologic improvement some softwares such as Adobe Photoshop have been released for image editing. However professional experience is required to be able to use those kinds of softwares efficiently and e diting photos by the indicated software is tiresome. In addition the .
