A 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 کاملAn Anisotrophic Diffusion Algorithm with Optimized Rotation Invariance
For strongly directed anisotropic diffusion filtering it is crucial to use numerical schemes with highly accurate directional behaviour. To this end, we introduce a novel algorithm for coherence-enhancing anisotropic diffusion. It applies recently discovered differentiation filters with optimal rotation invariance [10], and comes down to an explicit scheme on a 5×5 stencil. By comparing it with...
متن کاملA General Structure Tensor Concept and Coherence-Enhancing Diffusion Filtering for Matrix Fields
Coherence-enhancing diffusion filtering is a striking application of the structure tensor concept in image processing. The technique deals with the problem of completion of interrupted lines and enhancement of flow-like features in images. The completion of line-like structures is also a major concern in diffusion tensor magnetic resonance imaging (DT-MRI). This medical image acquisition techni...
متن کاملCoherence-enhancing diffusion of colour images
Many image processing problems require the enhancement of coherent ow-like structures. This can be accomplished in a natural way by combining anisotropic diiusion ltering and texture analysis by means of the structure tensor (second-moment matrix). In this paper an extension of these ideas to vector-valued images is presented. A structure tensor for vector-valued images is constructed as the su...
متن کاملMyofibre segmentation in H&E stained adult skeletal muscle images using coherence-enhancing diffusion filtering
BACKGROUND The correct segmentation of myofibres in histological muscle biopsy images is a critical step in the automatic analysis process. Errors occurring as a result of incorrect segmentations have a compounding effect on latter morphometric analysis and as such it is vital that the fibres are correctly segmented. This paper presents a new automatic approach to myofibre segmentation in H&E s...
