It serves as an AI assistant for rotoscoping a video sequence where a mask around an object is required to be updated through the whole video.

Adobe’s Roto Brush or DaVinci Resolve Magic Mask are alternative commercial products integrated into video editors. Cutie Roto is used as a standalone application where masks are exported as an image sequence and imported into the video editor. However, the open nature of Cutie Roto and its extensibility with newer versions of Cutie or other neural networks for the segmentation might be advantegous as an easy way to improve the quality of the results in the future. Also, the simple user interface makes it easier to use.
