An active-contour-interpolation approach is proposed for semi-automatic video object generation. In this approach, user can de ne the contour of the same video object on multiple frames and the computer interpolates the missing contours automatically. Typical active contour model is adapted and the contour interpolation problem is decomposed into two directional contour tracking problems and a ...

Speaker verification from talking a few words of sentences has many applications. Many methods as DTW, HMM, VQ and MQ can be used for speaker verification. We applied MQ for its precise, reliable and robust performance with computational simplicity. We also used pitch frequency and log gain contour for further improvement of the system performance.
