METHODS AND DEVICES FOR COMPRESSION AND RECOVERY OF ANIMATION PATH USING LINEAR APPROXIMATIONS

摘要

FIELD: animation of three-dimensional pictorial models. ^ SUBSTANCE: compression device has interpolation analysis unit for discriminating definite quantity of breakpoints on animation path and for outputting keys and key values corresponding to breakpoints; key coder; key value coder; and statistical coder. Analysis of breakpoints yields encoded bit stream having minimal quantity of breakpoints. ^ EFFECT: enhanced efficiency of data compression in interpolator form for fast data transfer and storage. ^ 20 cl, 35 dwg
