Abstract

In video encoding, there are seven block sizes used for inter-frame motion estimation/compensation for H.264.However, this feature requires the encoder to compute the rate-distortion cost for every available block mode. As a result, the complexity and computation load of video coding increase drastically. In this paper, a new fast inter mode decision method for H.264 coding standard was presented in order to reduce the computational complexity, which was based on the strong relativity of the adjacent frames in natural video. The method took a part of modes to reduce the complexity.
