Scale Adaptive Filtering Derived from the Laplace Equation

Download www.isy.liu.se

In this paper, we present a new approach to scale-space which is derived from the 3D Laplace equation instead of the heat equation. The resulting lowpass and bandpass ﬁlters are discussed and they are related to the monogenic signal. As an application, we present a scale adaptive ﬁltering which is used for denoising images. The adaptivity is based on the local energy of spherical quadrature ﬁlters and can also be used for sparse representation of images.
