Literature survey on motion estimation techniques

Abstract

Motion Estimation (ME) is one of the most intensive computational operations in video compression techniques. Video compression algorithm utilizes numerous standards such as MPEG1, MPEG4 AND H.261, H.264. Compression performance can be increased drastically by efficient motion estimation techniques by which energy is reduced within the residual frames involved in motion compensation. In this paper literature survey of motion estimation especially considering block matching ME (Motion Estimation). In this paper, comparison is made between the already existing block matching algorithms and their limitations in motion estimation along with their applications.

Efficient reconfigurable architecture for moving object detection with motion compensation

“…The accuracy of this estimation is directly related to the overall accurate detection. The three step search (TSS), the four step search (FSS), diamond search, successive elimination search and Indonesian J Elec Eng & Comp Sci ISSN: 2502-4752  Efficient reconfigurable architecture for moving object detection with motion compensation (Sridevi N.) 803 adaptive search window size [3]- [5] are some of most commonly used motion estimation algorithms, which generates high quality motion estimation, among those algorithms, full search motion estimation is widely used to estimate motion due to its various advantages over other estimation technique. Moreover, due to the complex data flow of most of those techniques, very large-scale integration (VLSI) level implementations are not possible.…”
