|Abstract: ||A fast block matching algorithm in the feature domain was proposed by Fok and Au which achieves a computation reduction factor of N/2 with search block size of NxN. This paper presents an improved fast block matching algorithm in the integral projections feature domain. This algorithm is based on the fast block matching algorithm in the feature domain and a new motion field sub-sampling scheme. By utilizing the properties of the features and the motion field sub-sampling scheme, with a search block size of NxN, the improved algorithm can achieve a computation reduction factor of N while retaining close-to-optimal performance in the mean absolute difference (MAD) sense.|
