Ordered shape contexts
WebJun 12, 2000 · We introduce a new shape descriptor, the shape context, for measuring shape similarity and recovering point correspondences. The shape context describes the coarse arrangement of the shape with respect to a point inside or on the boundary of the shape. We use the shape context as a vector-valued attribute in a bipartite graph … WebShape Matching with Ordered Boundary Points Using a Least-Cost Diagonal Method Carl E. Abrams, Sung-Hyuk Cha, and Charles C. Tappertt ... Abstract - The “ Shape Context” is a recently developed shape descriptor. It is an information rich descriptor that is invariant to translation, scale and rotation. It assumes that the boundary points which

WebDec 8, 2024 · To release this problem, this paper proposes a novel reverse time-ordered shape context to represent an air-writing trajectory in a backward way. This backward representation can effectively filter out them and thus simplify the matching process as a path finding problem. WebThis paper presents a method for matching closed, 2D shapes (2D object silhouettes) that are represented as an ordered collection of shape contexts [1]. Matching is performed …
WebApr 1, 2002 · In order to solve the correspondence problem, we attach a descriptor, the shape context, to each point. The shape context at a reference point captures the distribution of the remaining points relative to it, thus offering a globally discriminative characterization.

WebNov 1, 2016 · 4. Shape matching based on high-order graph matching. In this section, using interesting points described by point contexts, we firstly formulate shape matching as high-order graph matching consisting of potential functions with different orders. Then, we introduce the definition of each potential function.
