Interval algorithm and disk algorithm have the important applications in the field of curve and surface modeling design, such as intersection calculation of solid modeling design, collision detection of mechanical movement, error detection of industrial product form, etc.

Optimization coning algorithms to the fixed frequency motion;

Correction of coning algorithms considering the RLG signal filter characteristics;

A Simple Curve Adhesive Picture Algorithm based on Circle-Producing Algorithm;

The paper beging with a brief introduction to the dynamic mechanism of AA of ultrafine particles, then the dynamical equation of ultrafine particles aloustic agglomeration was solved with sectional algorithm(SA).

This paper systemtically reviews the color space and traditional approaches (including threshold,edge detection , watershed and merging), and introduces several new methods, such as edge detection based on deformable template , watershed based on wavelet transform and grain analysis based on mathematical morphology.
