Abstract
In the present paper, we propose Hermite polynomial integration method for Gaussian and Gaussian derivatives filtering in image smoothing an d edge detection. Hermite integration method for one dimensional (1D) Gaussian filtering is at first introduced, and its performance is anal ysed. The Hermite method is then generalized to Gaussian-derivative fi ltering and to multi-dimensional cases. Application for edge detection with a subpixel precision is presented as well. Experimental results, which confirm the theoretical analysis, are reported.
