Comparative Study of Gradient Domain Based Image Blending Approaches

The paper describes a comparative study of three different approaches that are used for image blending. The main focus will remain on the approaches where single source image and target is composed in the gradient domain. The main aim of the study is to portray the importance of considering gradients in image blending and why it makes the blending more realistic and effective. The study of all the approaches that are taken under consideration have been executed using MATLAB. The three different approaches are Naive blending, poisson image blending and Mixed gradient approach of image blending.
