Digital face beautification utilizing TV filter and super-resolution technology

In this paper, we apply a total variation (TV) filter and super-resolution technology to the image processing of human face beautification. We focus on two aspects: one is smoothing of the facial skin; the other is emphasizing the parts of the face. Facial skin smoothing has already been addressed using nonlinear filters, but the effective removal of moles and stains was not successful. We solved this problem utilizing a TV filter, and obtained good results. For emphasizing face parts, we utilize the face-part detection and super-resolution technology that we have developed for 4K-HDTV. This work is not computer graphic technology that modifies face shape, but can be addressed as a digital cosmetic using recent state-of-the-art image signal processing technologies.
