Title: | Exact computation of area moments for spline and wavelet curves | Authors: | Jacob, Mathews THIERRY BLU Unser, Michael |
Issue Date: | 1-Dec-2000 | Journal Volume: | 15 | Journal Issue: | 3 | Source: | Proceedings - International Conference on Pattern Recognition | Abstract: | 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 show that the computation of the area moments is equivalent to applying a suitable multidimensional filter on the coefficients of the curve and thereafter computing a scalar product. We compare this algorithm with existing methods such as pixel-based approaches and approximation of the region by a polygon. © 2000 IEEE. |
