featurepreserving
Featurepreserving refers to techniques that retain salient data features such as edges, corners, ridges, and texture boundaries during processing that can otherwise blur or distort those features. It is applied to image denoising, smoothing, resizing, upsampling, compression, and geometric processing of meshes and point clouds.
In image processing, feature preservation aims to reduce noise while maintaining sharp transitions. Techniques include edge-preserving
In geometry and computer graphics, feature-preserving methods protect sharp edges and corners during smoothing, remeshing, or
Evaluation and trade-offs: measures used to assess feature preservation include edge preservation indices, gradient magnitude differences,
Applications span computer vision, medical imaging, and computer graphics, where maintaining structural detail during denoising, compression,
