The classic fast search algorithm can effectively reduce the volume of search

but because of their selective searching it will easily fall into the local optimal error. The Multiresolution Motion Estimation (MRME) and the Wavelet Multiresolution Motion Estimation (WMRME) can reduce the local optimal error to a certain extent

but they also bring a corresponding increase in computing capacity. Based on the Wavelet Multiresolution Motion Estimation

a Wavelet Leapfrog multiresolution Motion Estimation (WLMRME) algorithm is proposed.Combined with a rapid search algorithm

WLMRME can achieve better coding effect with less complexity than WMRME.
