Visual media in the form of television programs, online video, and cinematic films have the power to engage people with dynamic, presentations of ideas. Expert storytellers design how such media unfolds over time to help audiences make sense of complex concepts, appreciate cultural or societal differences and imagine living in entirely different worlds. Technological advances have made it cheaper and easier to capture audio-visual media using the video cameras that are readily available in our mobile and desktop devices. Yet, the most viewed video are not simply raw recordings thrown onto the Web. The best material is carefully composed, filtered and edited to ensure that the resulting media is clear and engaging.
Nevertheless, today’s tools for authoring and viewing video treat the media as a “baked” stream of audio samples, pixels, and frames – the very lowest-level representation possible. They have no understanding of the higher-level semantic structure of the audio-visual content. Researchers have developed a variety of techniques for extracting such higher-level structure from video and shown how to use this structure to significantly facilitate analysis, browsing, editing and manipulation of the raw material.
The goal of this graduate seminar (advanced undergraduates also welcome) is to survey recent work on computational video analysis and manipulation techniques. We will learn how to acquire, represent, edit and remix video. Several popular video manipulation algorithms will be presented, with an emphasis on using these techniques to build practical systems. Students will have the opportunity to acquire their own video and develop the processing tools needed to computationally analyze and manipulate it.
There are no official prerequisites for the course, but we will expect familiarity with the basic concepts of Computer Graphics and/or Computer Vision at the level of CS 148/248 and/or CS 131. Contact me (Maneesh) via email if you are worried about whether you have the background for the course.

Attendance Requirement: This course relies on you reading the assigned papers and participating in the discussions. Therefore attendance is mandatory.
Plagiarism Policy: Assignments should consist primarily of your original work, building off of others’ work–including 3rd party libraries, public source code examples, and design ideas–is acceptable and in most cases encouraged. However, failure to cite such sources will result in score deductions proportional to the severity of the oversight.
