    Combined filtering and keyframe reduction for motion capture data
    (2007) Önder, Onur
    Two new methods for combined filtering and key-frame reduction of motion capture data are proposed. Filtering of motion capture data is necessary to eliminate any jitter introduced by a motion capture system. Although jitter removal is needed to obtain a more realistic animation, it may result in an oversmoothed motion data if it is not done properly. Key-frame reduction, on the other hand, allows animators to easily edit motion data by representing animation curves with a significantly smaller number of key frames. One of the proposed techniques achieves key frame reduction and jitter removal simultaneously by fitting a Hermite curve to motion capture data using dynamic programming. Another method is to use curve simplification algorithms on the motion capture data until the desired reduction is reached. In this research, the results of these algorithms are evaluated and compared. Both subjective and objective results are presented.

    Technological construction of performance: case of Andy Serkis
    (2017-01) Balcı, Ceren
    Performance in film can be considered as a construction that goes beyond mere recording of the actors to comprise a synthesis of discrete elements that have been removed from their original contexts, rearranged, and reshaped. Today, owing to digital effect technology such as motion capture and digital compositing, the film industry shows an advanced degree of these processes that allows filmmakers to influence, reconstruct, and even alter the actor’s performance. This study examines the technological construction of performance, dealing especially with motion capture technology in Hollywood blockbusters. This study relies on an analysis of specific performances in order to explore how they have been constructed with the help of technological intervention. As the main case study, the career of Andy Serkis, the most visible example of the motion capture actor, is analyzed to understand and discuss how the technology is perceived in terms of screen performance.
