[edit] Description
Video retargeting is the problem of modifying the size and/or aspect ratio of a video. This is useful for displaying videos where the dimensions of the screen are different than the dimensions of the video file, the most common example of which is watching a widescreen movie on a square television screen. However, it is becoming more important as the number of video display devices (ipods, cell phones, etc.) increase, as well as the number of video sources (youtube, etc.) The two traditional approaches for video retargeting are simply cropping an area of each video frame (pan and scan), or adding black bars to the top and bottom or sides of the video (letterboxing). In this paper I will explore automatic video retargeting using a recent paper by Wolf et. al. as a starting point. I will extend this work to better handle motion in the scene by incorporating optical flow and I will improve the results by using a global optimization of the entire video at once.
