|Title:||Image Filtering Based on Locally Estimated Geodesic Functions|
|Authors:||GRAZZINI Jacopo; SOILLE Pierre|
|Type:||Articles in periodicals and books|
|Abstract:||This paper addresses the problem of edge-preserving smoothing of natural images. A novel adaptive approach as a preprocessing stage in feature extraction and/or image segmentation. It performs a weighted convolution by combining both spatial and tonal information in a single similarity measure based on the local calculation of geodesic time functions. Two different strategies are derived for smoothing heterogeneous areas while preserving relevant structures.|
