摘要:

各向异性非线性扩散是一种强大的图像处理技术,它可以同时去除噪声和增强二维或三维图像中的尖锐特征。在Weickert的意义上理解各向异性扩散,这意味着扩散张量是各向异性的,反映了图像特征的局部方向。这与Perona和Malik的非线性扩散滤波器形成对比,后者仅涉及标量扩散系数,换句话说,各向同性扩散张量。在本文中,我们提出了一个各向异性的非线性扩散技术,我们在ITK实现。这种技术是基于最近的自适应计划,使扩散稳定,需要有限的数值资源。(See补充资料)。

英文摘要:

Anisotropic Non-Linear Diffusion is a powerful image processing technique, which allows to simultaneously remove the noise and enhance sharp features in two or three dimensional images. Anisotropic Diffusion is understood here in the sense of Weickert, meaning that diffusion tensors are anisotropic and reflect the local orientation of image features. This is in contrast with the non-linear diffusion filter of Perona and Malik, which only involves scalar diffusion coefficients, in other words isotropic diffusion tensors. In this paper, we present an anisotropic non-linear diffusion technique we implemented in ITK. This technique is based on a recent adaptive scheme making the diffusion stable and requiring limited numerical resources. (See supplementary data.)
