A New Fast Search Algorithm Based on Wavelet Domain
|
Abstract:
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 Multi-resolution Motion Estimation (MRME) and the Wavelet Multi-resolution 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 Multi-resolution Motion Estimation,a Wavelet Leapfrog multi-resolution Motion Estimation (WLMRME) algorithm is proposed.Combined with a rapid search algorithm,WLMRME can achieve better coding effect with less complexity than WMRME.
