Contour-Point Signature: A New Descriptor for Matching Rigid Shapes with a Single Closed Contour
Shape matching and point correspondence recovering play a fundamental role in applications like pattern and object recognition, shape classification, image alignment and registration, visual information data mining, and many other computer vision related areas, which recently became active research disciplines due to the increasing needs in many practical fields. This article introduces the Con...
متن کاملThe political reference point: How geography shapes political identity
It is commonly assumed that how individuals identify on the political spectrum-whether liberal, conservative, or moderate-has a universal meaning when it comes to policy stances and voting behavior. But, does political identity mean the same thing from place to place? Using data collected from across the U.S. we find that even when people share the same political identity, those in "bluer" loca...
متن کاملMatching Shapes
We present a novel approach to measuring similarity between shapes and exploit it for object recognition. In our framework, the measurement of similarity is preceded by ( I ) solving for correspondences between points on the two shapes, ( 2 ) using the correspondences to estimate an aligning transform. In order to solve the correspondence problem, we attach a descripto< the shape context, to ea...
متن کاملArticulated Matching with Point
Articulated matching arises naturally in object recognition and tracking. When a part-based description of an object is adopted, the problem of matching the model features to the data can be decomposed into matching the parts while paying attention to overall model coherence. Here we focus on the rst part of the problem, namely, the articulated matching of a part based description of an object ...
متن کاملStrong matching of points with geometric shapes
Let P be a set of n points in general position in the plane. Given a convex geometric shape S, a geometric graph GS(P ) on P is defined to have an edge between two points if and only if there exists a homothet of S having the two points on its boundary and whose interior is empty of points of P . A matching in GS(P ) is said to be strong, if the homothets of S representing the edges of the matc...
