Detecting missing frames in videos

Abstract

Although there are many video completion algorithms, ranging from object removal to reconstructing missing frames, little work has been done in the field of automatically detecting missing frames to begin with. This means manual work, thus we seek to propose a method that detects the locations of missing frames automatically. Our proposed method is based on the Edge Change Ratio algorithm, which was originally developed to detect scene breaks. We look at a number of factors and how they influence the algorithm, and adapt it to our needs. Results indicate that our method works fairly well, and with some more work, can automatically and reliably detect missing frames regardless of resolution, framerate, or the actual content of the video.
