This algorithm first selects several codebook sizes for each mode and then calculates the quantization distortion of each codebook size to find a codebook size allocation with the least quantization distortion for a given sum of all the codebook.

Calibration of wave slopes in the color coding method;

The subject\'s identification situation to the different color codings was evaluated and analyzed by the experiment,in which mental workload is controlled by changing display frequency of task information and correct response rate and reaction time are regarded as performance indicators,to provide a scientific basis for designing ergonomics of information display interface.
