Corner detection using the MAP technique
Proceedings of 12th International Conference on Pattern Recognition, 2002This paper describes a corner detection method that obtains maximum a posteriori estimates for the corner location in a given sequence of points. The authors model an ideal corner as the intersection of two ideal line segments. The perturbations on the sample points in a given line segment are assumed to be i.i.d Gaussian random variables of zero mean ...

A MORPHOLOGICAL OPERATOR FOR CORNER DETECTION
Pattern Recognition, 1998Abstract This paper presents a new operator for corner detection. This operator uses a variant of the morphological closing operator, which we have called asymmetrical closing. It consists of the successive application of different morphological operators using different structuring elements. Each of these structuring elements used to probe the image

Corner detection in curvilinear dot grouping
Biological Cybernetics, 1988Corners, or discontinuities in orientation, are one of the most salient and useful properties of contours. But how sensitive are we in detecting them, and what does this sensitivity imply about the processes by which corners can be detected. In this paper we address both of these questions, starting with the observation that changing the sampling phase

Corner detection based on estimated eigenvalues
Proceedings of the 23rd Spring Conference on Computer Graphics, 2007Corner detection is important part of many image analysis methods and the result of corner detection is essential for performance of stereo vision, augmented reality, etc. This paper proposes a new method of corner detection based on autocorrelation matrix estimated eigen-values and compares the new method with several frequently used methods The new ...

Detecting corners of polygonal and polyhedral objects
1993In this paper, we proposed a novel corner detection algorithm, based on statistical properties of corners, to detect corners of both polygonal and polyhedral objects. By means of local histogram analysis, we first bilevel the subimage within a circular window, then compute the intensity mean for the bileveled subimage.
