Abstract

In this letter, we propose a new logarithmic rate distortion model for DCT-based video encoders. The proposed model can fit into the actual rate curve by combining several logarithmic functions, where the boundary of each function is adaptive to the statistics of video sequence. Experimental results demonstrate that the new rate distortion model provides a more accurate estimation of the bit rate than existing models.
