Orientation estimation for corner detection
نویسندگان
چکیده
Although many work have been done on corner detection, no generally accepted mathematical definition exists. This paper gives an explicit definition of corner which is based on the multi-orientation nature of corner and presents an algorithm for corner detection based on orientation estimation. Experimental results show that the proposed algorithm is more accurate and noise-robust compared with three popularly used corner detection algorithms. Keywords-Corner detection; Orientation estimation; orientation tensor; nonlinear diffusion

Corner validation based on extracted corner properties
We developed a method to validate and filter a large set of previously obtained corner points. We derived the necessary relationships between image derivatives and estimates of corner angle, orientation and contrast. Commonly used cornerness measures of the autocorrelation matrix estimates of image derivatives are expressed in terms of these estimated corner properties. A candidate corner is va...
متن کاملA Simple Corner Orientation Detector
This paper describes a new simple and fast method, elaborated and tested by authors, for corner orientation detection. The conventional L-, T-, Yand Xcorner or junctions are important dominant features belonging to object patterns in digital images. A small set of locally defined parameters: position, orientation, scale, phase and curvature can characterize these elementary structures. „Orienta...
متن کاملA new method of camera pose estimation using 2D-3D corner correspondence
Estimation of camera pose from image to space feature correspondence is a basic problem in image analysis and understanding. This paper presents a new method for the estimation of camera pose from 2D to 3D corner correspondence. Two cases are considered: the orthogonal corner and the general corner. The contribution of the work is in two folds: one is that the camera pose parameters, i.e., the ...
متن کاملRobust Corner Detection by Image-Based Direct Curvature Field Estimation for Mobile Robot Navigation
In this paper, a novel corner detection method is presented, to extract geometrically important corners for robot applications, such as indoor mobile robot navigation or manipulation. Intensity‐based corner detectors, such as the Harris corner, can detect corners in noisy environments, but have inaccurate corner positions and miss the corners of obtuse angles. Edge‐based corner det...
متن کاملGlobal Curvature Estimation for Corner Detection
The paper starts with presenting three curvature estimators which follow definitions (approaches) in differential geometry. Digital-straight segment (DSS) approximation is used in those estimators, we point to problems caused by this approach, and propose simple ways for eliminating those problems. The paper then informs about multigrid analysis experiments, where all estimators appear to be mu...
