Wipe shot boundary determination

A new efficient and fast algorithm for wipe detection and determination is proposed. It can be used on the luminance DC coefficients extracted from MPEG sequences in compressed domain or on spatially sub-sampled sequences. An evenness factor is defined and proposed to be used to exploit the observation that during a wipe spatial zones of change move thru the image. Wipe candidates are checked with frame differences of frame pairs with certain temporal distances. For the remaining candidates usage of a new approach for the detection of uniform movement of linear zones of change using double Hough transform is proposed. The algorithm has a low computational complexity and handles motion well.
