Estimation of Subpixel Motion Using Bispectrum

الملخص EN

Motion estimation techniques are widely used in today's video processing systems.

The frequently used techniques are frequency-domain motion estimation methods, most notably phase correlation (PC).

If the image frames are corrupted by Gaussian noises, then cross-correlation and related techniques do not work well.

In this paper, however, we have studied this topic from a viewpoint different from the above.

Our scheme is based on the bispectrum method for sub-pixel motion estimation of noisy image sequences.

Experimental results show that our proposed method performs significantly better than PC technique.
