The sub-pixel algorithm computes the image curvature directly on the smoothed level lines, and yields a microscopic visualization of the curvature map revealing many image details, and getting rid of aliasing effects. This "curvature microscope" showing curvatures in false colors runs on line on any image proposed by users at http://www.ipol.im/pub/algo/cmmm_image_curvature_microscope/. %G English %2 https://enpc.hal.science/hal-00654440/document %2 https://enpc.hal.science/hal-00654440/file/ICIP2010.pdf %L hal-00654440 %U https://enpc.hal.science/hal-00654440 %~ ENPC %~ UPMC %~ CNRS %~ UNIV-MLV %~ ENS-CACHAN %~ LIGM_A3SI %~ PARISTECH %~ LJLL %~ LIGM %~ CV_LIGM %~ IMAGINE %~ ESIEE-PARIS %~ SORBONNE-UNIVERSITE %~ SU-SCIENCES %~ SU-TI %~ CMLA %~ FARMAN %~ ENS-PARIS-SACLAY %~ ALLIANCE-SU %~ UNIV-EIFFEL %~ UPEM-UNIVEIFFEL %~ ESIEE-UNIVEIFFEL %~ TEST3-HALCNRS
