Experimental results show that combining these techniques provides high-speed and high-precision motion estimators with reduced on-chip buffers and lowered input bandwidth requirements. © 1994 IEEE.application/pdf264039 bytesapplication/pdfen-USMotion compensation; Motion estimation; Bandwidth requirement; Block matching algorithms; Hierarchical search block matching; High Speed; High-precision motion; Input datas; On-chip buffers; Video signal processingModifications and performance improvements of 3-step search block-matching algorithm for video codingconference paper10.1109/SIPNN.1994.3449182-s2.0-85064688282http://ntur.lib.ntu.edu.tw/bitstream/246246/2007041910032452/1/00344918.pdf
