Automation of parts segmentation in 2D character animation production

A process of 2-dimensional (2D) character animation is to segment an illustration into parts such as a face outline or hair. This is a simple and time-consuming process, which involves cutting out the parts to be animated from an illustration. In this study, we focus on automation of the segmentation of the parts of a 2D character animation. Moreover, to improve the accuracy of the process, we combine U-net and pix2pix. Based on the accuracy evaluation, we confirmed that the accuracy of the F-measure of the proposed method is 81.1%, which outperformed U-net and pix2pix by 15.5% and 0.9%, respectively.
