| Abstract: |
Integral projections have been proposed as an efficient method to reduce the dimensionality of the search space in motion estimation (ME) algorithms. A number of papers describe methods extending direct (correlation based) block matching algorithms with projections, others derive optical flow methods based on the Radon transform. With a single exception all of the above methods use a single horizontal and vertical projection to keep the ME algorithm computationally simple. In this work we derive a generalization on the direct projection methods: a ME method based on backprojections, and investigate the added value of using multiple projection angles. |
