Edge and corner preserving smoothing for artistic imaging
SPIE Proceedings, 2007What visually distinguishes a painting from a photograph is often the absence of texture and the sharp edges: in many paintings, edges are sharper than in photographic images while textured areas contain less detail. Such artistic effects can be achieved by filters that smooth textured areas while preserving, or enhancing, edges and corners.

Detection of corners and smooth joins using wavelet transform
ISCAS'99. Proceedings of the 1999 IEEE International Symposium on Circuits and Systems VLSI (Cat. No.99CH36349), 2003In this work a new computationally efficient algorithm is presented to detect both corners and smooth joins which is robust and simple. It consists of two stages: the first stage detects corners or dominant points, and the second stage detects point of inflection and smooth joins. Here a wavelet based technique is presented to detect all these features

SEMIREGULAR CORNER SINGULARITIES OF SMOOTH FUNCTIONS
Mathematics of the USSR-Sbornik, 1991The \(m\)-angular singular points of smooth functions with nondegenerate second differentials are considered. The bifurcation diagrams of angular singularities are investigated. Such singularities of smooth functions arise in variational problems which are equivariant relative to systems of involutions commuting on the spans of principal modes of ...

Local corner cutting and the smoothness of the limiting curve
Computer Aided Geometric Design, 1990Abstract Stimulated by recent work by Gregory and Qu, it is shown that the limit of local corner cutting is a continously differentiable curve in case the corners of the iterates becomeincreasingly flat.

An Improved Corner Detection Algorithm Based on Gaussian Smoothing
2010 International Conference on Intelligent Computation Technology and Automation, 2010Corner point is the pixel with a high curvature on image edge. It is a key feature in digital image processing. Through the utilizing of corner points in image processing tasks, the computational complexity can be highly reduced. This paper proposes an improved corner detection algorithm.
