Research on rate-distortion cost estimation model for H.264
A new rate distortion cost estimation model was proposed.To provide more accurate estimation of the number of coding bits for encoding intra / inter macro blocks,firstly a new bit rate estimation model was proposed.The rate estimation was a linear combination of existing coding parameters,which were...

| description | A new rate distortion cost estimation model was proposed.To provide more accurate estimation of the number of coding bits for encoding intra / inter macro blocks,firstly a new bit rate estimation model was proposed.The rate estimation was a linear combination of existing coding parameters,which were more accurately related to entropy coding and transform coefficients.Secondly a new rate distortion cost estimation model which had superior performance was given.Finally,a detailed analysis on the rate distortion cost estimation model from many aspects such as the effect and the performance was taken.Experimental results show that the encoding speed is greatly accelerated in ensuring little change both in PSNR and coding bits. |
