We present a novel technique for detecting the presence of a wipe transition in video sequences and automatically identifying its type. Our scheme focuses on analyzing the characteristics of the underlying special edit effects and estimates actual transitions by polynomial data interpolation. In particular, a B-spline polynomial curve fitting technique is used to measure 'goodness' of fitting to determine the presence of gradual transitions. Our approach is able to recover the original transition behavior of an edit effect even if it is distorted by various post- processing stages. Our wipe transition detector has been tested on various real video sequences to evaluate the performance of the proposed algorithms.
