"Video Cosmetics: Digital Removal of Blemishes from Video"

By

Mr. Yau-Chat Tsoi


Abstract

Visible facial blemishes can be annoying and embarrassing in our daily
lives. This is particularly true when blemishes are permanently captured
on video. For film and broadcast production, blemishes on actors/actresses
may not be acceptable and must often be removed by post-production
processing. Such processing can be incredibly slow and tedious, requiring
a digital artist to "retouch" the video footage frame-by-frame. For
amateur video editing, this manual processing is impractical with existing
tools.

This thesis presents a unique framework, referred to as Video Cosmetics
(VC), designed to remove unwanted blemishes from video footage with
minimal user assistance. Using the VC framework a user needs only to
specify the blemish in an initial frame; the system will then
automatically track and remove the blemishes from subsequent frames. This
task is accomplished by combining feature tracking, pixel classification,
and temporally coherent image inpainting into a single processing
framework.  The result is an efficient post-production tool that
substantially reduces the amount of time and effort needed to remove
blemishes from video footage.
