Pel-recursive motion estimation algorithm
H. Gharavi, Hamid‐Reza Reza‐Alikhani · Electronics Letters · 2001
A new pel-recursive motion estimation algorithm for video coding applications is presented. The derivation of the algorithm is based on recursive least-squares estimation that minimises the mean-square prediction error. A comparison with the modified steepest-descent gradient estimation technique algorithm shows significant improvement in terms of mean-square prediction error performance.
