Coherence - Enhancing Di usion
نویسنده
چکیده
The completion of interrupted lines or the enhancement of ow-like structures is a challenging task in computer vision, human vision, and image processing. We address this problem by presenting a multiscale method in which a nonlinear diiusion lter is steered by the so-called interest operator (second-moment matrix, structure tensor). An m-dimensional formulation of this method is analysed with respect to its well-posedness and scale-space properties. An eecient scheme is presented which uses a stabilization by a semi-implicit additive operator splitting (AOS), and the scale-space behaviour of this method is illustrated by applying it to both 2-D and 3-D images.

A New Scheme for Anisotropic Di usion: Performance Evaluation of Rotation Invariance, Dissipativity and EÆciency
For strongly directed anisotropic di usion ltering it is crucial to use numerical schemes with highly accurate directional behaviour. To this end, we introduce a novel algorithm for coherence-enhancing anisotropic di usion. It applies recently discovered di erentiation lters with optimal rotation invariance [11], and comes down to an explicit scheme on a 5 5 stencil. By comparing it with severa...
متن کاملAnisotropic Di usion of Noisy Surfaces and Noisy Functions on Surfaces
We present a uni ed anisotropic geometric di usion PDEmodel for smoothing (fairing) out noise both in triangulated 2-manifold surface meshes in IR and functions de ned on these surface meshes, while enhancing curve features on both by careful choice of an anisotropic di usion tensor. We combine the C limit representation of Loop's subdivision for triangular surface meshes and vector functions o...
متن کاملA Scheme for Coherence-Enhancing Diffusion Filtering with Optimized Rotation Invariance
For strongly directed anisotropic processes such as coherence-enhancing di usion ltering it is crucial to use numerical schemes with highly accurate directional behavior. We show that this is not possible in a satisfactory way when discretizations are limited to 3 3 stencils. As a consequence, we investigate a novel algorithm based on 5 5 stencils. It utilizes recently discovered di erentiation...
متن کاملLow Bit Rate Image Coding in the Scale Space
Scale-space representation has been extensively studied in the computer vision community for analyzing image structures at di erent scales. This paper borrows and develops useful mathematical tools from scale-space theory to facilitate the task of image compression. Instead of compressing the original image directly, we propose to compress its scale-space representation obtained by the forward ...
متن کاملAn Input-Level Dependent Approach to Color Error Di usion
Conventional grayscale error di usion halftoning produces worms and other objectionable artifacts. Tone dependent error di usion (Li and Allebach) reduces these artifacts by controlling the di usion of quantization errors based on the input graylevel. Li and Allebach optimize error lter weights and thresholds for each (input) graylevel based on a human visual system model. This paper extends to...
