Then a optimizing method based on rate-distortioncurve is used to make reasonable bit-allocation among the blocks.

This article use the mechanics and limited finite element idea to disperse the whole pipe. The distortioncurve is drawn in various circumstance by the iteration programming.
The distortion coefficients can be set manually, by using curves available in the curve Editor, or can be calculated by drawing measurement lines in the clip.
