DCT-domain image registration techniques for compressed video

A technique for image registration in compressed video, such as motion JPEG or the I-picture of MPEG, is investigated. The technique is based on DCT (discrete cosine transform) coefficient matching. First, the coarse edge features are extracted by applying several edge detectors to luminance DC coef...
