We propose an integrated wavelet-based framework of the active contour model(snake) for segmentation and motion tracking of deformable objects in video sequences. The input image frame is represented by means of wavelet transform. First, the moduli of wavelet transform coeecients are used in a multi-resolution motion estimation process to nd the initial snake contour in the current frame. The presented multi-resolution motion estimation methods allow a larger movement of the tracked object than… CONTINUE READING
