Optimized polygonal approximations through vertex relocations in contour neighborhoods

作者：

Highlights：

• Polygonal approximations using relaxed approximations allowing the vertices of an approximation to lie outside the contour.

• Adaptive estimation of contour neighborhoods where the vertices of an approximation are located.

• A general approach to reduce error measure of any polygonal approximations through vertex relocation.
