Quality assessment of point group geometry generalization with polarization transformation

Analysing circle characters and the feasibility of using it to quality assessment of point group generalization, a new method of assessing point cluster geometry quality is developed based on the technique of polarization transformation. Thus the whole transformation process is expatiated on. In order to retain character of point group and integrality of point cluster, this paper puts forward the measure of quality assessment guideline, and the method of quantitating guideline. Furthermore, with analysing dynamically the guideline values, this paper gathers up the integral evaluation guideline such as characteristic point retain ratio, cluster quantity retain ratio, cluster outline retain ratio and point object deletion ratio etc, these guidelines are used to further quality assessment.
