报告摘要:
Compensated convex transforms are simple convexity based`tight’ approximations of functions. Applications so far include imageprocessing, geometric singularity extraction, such as surface intersection,stable ridge transform, the medial axis map; interpolation and approximation ofsampled functions, and smoothing in convex optimization.An interesting featureof such transforms is the Hausdorff stability which provides robustness of thetransforms. I will present a brief introduction to the theory and numericalmethods, and describe some of the applications mentioned above.
