Abstract

In order to estimate highly reliable motion for image sequences, a novel segment-based motion estimation is described. Segmentation is performed based on zero-crossings of the wavelet transform. Moving objects are extracted from the area of motion using the segmentation result. Multiresolution image decomposition is performed with the biorthogonal wavelet transform, and then motion is hierarchically estimated using the segmentation result. Moving objects and covered/uncovered areas are identified with the segmentation result and the estimated motion information. Finally, the application to motion compensated interpolation to the above is described.
