Similitude Included Angle Theorem and Application in Graphics
Zhou De-long · 2009
In this paper we bring forward an image edge similitude extent algorithm based on the steadiness character theorem of plane similitude graphics—similitude included angle theorem,and the algorithm is realized by constructing an AFMSDF(mean-square deviation function of angle fluctuation).The AFMSDF is used as a method of scaling the similitude extent of two different edge contours.This algorithm provides a reasonable method for graphic match,graphic search,efficient graphic similitude transform,and clustering,etc.Theoretical analysis and experiments indicate that the method is feasible.
