An Effective Variable Block-Size Early Termination Algorithm for H.264 Video Coding

An Effective Variable Block-Size Early Termination Algorithm for H.264 Video Coding

achieved while 外汇交易入门 the degradation in video quality is negligible.

Index Terms—Early termination,H.264,motion estimation,

R ECENT years have seen rapid development of video

coding techniques.Generally,compression performance

is improved along with an increase of computational cost.外汇交易入门

H.264,as the newest joint standard of the ITU-T Video Coding

Experts Group(VCEG)and the ISO/IEC Moving Picture Ex-

perts Group(MPEG),has achieved a signi?cant improvement

in coding ef?ciency compared to previous standards,such as

MPEG-1/2/4and H.261/H.263.However,its complexity is too

high to be widely applied in real-time applications.

In general,motion estimation(ME)contributes most of the

complexity of a video encoder.There are two ways to reduce

the computational cost.The?rst one is to speed up the algo-

rithms themselves.For ME,numerous fast algorithms have been

proposed,such as hexagon-based search(HBS)[5],enhanced

predictive 外汇交易入门 zonal search(EPZS)[3],and hybrid unsymmetrical-

cross multihexagon-grid search(UMHexagonS)[1].The other

way is to terminate the ME calculation early.By predicting the

blocks whose discrete cosine transform(DCT)coef?cients will

quantize to zeros,some methods[2],外汇交易入门 [6],[4]effectively reduce
