Vectorization in Graphics Recognition: To Thin or Not to Thin
Vectorization, i.e. raster–to–vector conversion, is a central part of graphics recognition problems. In this paper, we discuss the pros and the cons of basing one’s vectoriz...

Piecewise Linear Two-Dimensional Warping
A new efficient dynamic programming (DP) algorithm for 2D elastic matching is proposed. The present DP algorithm requires by far less complexity than previous DPbased elastic mat...

Exact Computation of Area Moments for Spline and Wavelet Curves
We present an exact algorithm for the computation of the moments of a region bounded by a curve represented in a scaling function or wavelet basis. Using Green's theorem, we ...
