An enhanced hierarchical method for true motionestimation is presented that not only produces consistent motion vectors within each large object but also accurately estimates the motion of small objects. Experimental results show that a frame interpolation method provided with the motion fields of the proposed algorithm achieves average PSNR improvements of 1.2-2.3 dB for interpolated frames as compared with those of conventional algorithms.
The authors propose a hierarchical motion estimation algorithm in which the sum of the absolute difference in the Hadamard transform domain is used as its matching measure. The computational complexity of this algorit...

The authors propose a hierarchical motion estimation algorithm in which the sum of the absolute difference in the Hadamard transform domain is used as its matching measure. The computational complexity of this algorithm was reduced to similar to 5.6% while the image degradation of its reconstructed image quality was < 0.1 dB on average, compared with that of the full search in the pixel domain.
