Ridge's corner detection and correspondence
نویسندگان
چکیده
Traditionally, corners are found along step edges. In this paper, we present an alternative approach corners along ridges/troughs and local minima points. These features seem to be more reliable for tracking. A new approach for sub-pixel localization of these corners is suggested, using a local approximation of the image surface.

Corner Detection of Hand Gesture
This paper studies the methods of corner detection of hand gesture, and mainly introduces the orthogonal three-direction chain code (3OT) and uses it in corner detection of hand gesture. The study is discussed from four aspects: the techniques used in corner detection, the techniques of Freeman chain code, the main idea of 3OT, the process of corner detection with 3OT and the experiments on cor...
متن کاملCSE 252 B : Computer Vision
Last lecture we learned how to find interest points using the Förstner corner detector. The goal of this lecture is to find correspondences between these points automatically. This is known as the correspondence problem. The correspondence problem is arguably the hardest problem in structure from motion (SFM). For example, one must deal with pointsets of different length, with spurious coordina...
متن کاملElectrostatic Field-Based Multiscale Corner Detection: A Physics-Motivated Approach
Corners represent special features of interest in images. They are very useful in many vision problems such as optical ow, structure from motion, and motion correspondence. A corner may be deened as the junction point between two or more straight line edges, or a point on the object's boundary curve having a curvature extremum. Our deenition of a corner is a point having an electrostatic eld ex...
متن کاملImage Matching by Multiscale Oriented Corner Correlation
In this paper we present a simple but effective method for matching two uncalibrated images. Feature points are firstly extracted in each image using a fast multiscale corner detector. Each feature point is assigned with one dominant orientation. The correspondence of feature points is then established by utilizing a multilevel matching strategy. We employ the normalized cross-correlation defin...
متن کاملEfficient Fuzzy Set Theoretic Approach to Image Corner Matching
Corner matching in digital images is a key step in several applications in computer vision such as motion estimation, object recognition and localization, 3D reconstruction etc. Accuracy and reliability of corner matching algorithms are two important criteria. In this paper, corner correspondence between two images is established in the presence of intensity variations, inherent noise and motio...
