Texture: Plus ça change, …

Research output: Chapter in Book/Report/Conference proceedingConference contribution


This paper presents an edge finder for textured images. Using rough constraints on the size of image regions, it estimates the local amount of variation in image values. These estimates are constructed so that they do not rise at boundaries. This enables subsequent smoothing and edge detection to find coarse-scale boundaries to the full available resolution, while ignoring changes within uniformly textured regions. This method extends easily to vector valued images, e.g. 3-color images or texture features. Significant groups of outlier values are also identified, enabling the edge finder to detect cracks separating regions as well as certain changes in texture phase.
