In this work we focus on the challenging problem of enhancing the aesthetic appeal (or the attractiveness) of human faces in frontal photographs (portraits), while maintaining close similarity with the original. The key component in our approach is an automatic facial attractiveness... This exercise is an introduction to gradient domain image editing. We start with the simpler smooth image completion operation (an example input/out pair is on the left). We continue to describe the poisson image cloning technique that involves cloning pixel-gradients instead of pixel values and usually results in a smoother blending. The exercise material includes the presentation slides and full solution source-code... these operations on video in the gradient domain. Our approach consists of 3D graph cut computation followed by reconstruction of a new 3D vector field by solving the Poisson equation. We demonstrate the applicability of smooth video transitions by fusing pairs for video mosaics, video..
