Matching with Shape Contexts
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 (1) 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 descriptor, the shape context, to each ...
متن کامل3D Shape Matching with 3D Shape Contexts
Content based 3D shape retrieval for broad domains like the World Wide Web has recently gained considerable attention in Computer Graphics community. One of the main challenges in this context is the mapping of 3D objects into compact canonical representations referred to as descriptors or feature vector, which serve as search keys during the retrieval process. The descriptors should have certa...
متن کاملFast Shape Matching and Shape Analysis Using Shape Contexts and Wavelet Transform
Shape matching or recognition is computation intensity work in shape analysis. Paper [3] proposed an efficient shape matching method using shape contexts (SC). In this project, wavelet transform is used to scale or compress images into much smaller sizes and then shape context algorithm is used to match shapes. Simulation results show that the matching speed is faster and matching results are m...
متن کاملEfficient Shape Matching using Vector Extrapolation
We propose the adoption of a vector extrapolation technique to accelerate convergence of correspondence problems under the quadratic assignment formulation for attributed graph matching (QAP). In order to capture a broad range of matching scenarios, we provide a class of relaxations of the QAP under elastic net constraints. This allows us to regulate the sparsity/complexity trade-off which is i...
متن کاملEfficient Shape Retrieval Using Elliptical Shape Coding
This paper presents a novel shape representation, called elliptical shape coding, and uses it to develop an efficient shape retrieval algorithm. The elliptical shape coding transforms an original shape, which is a single, closed contour in our experiments, into a periodic signal. The alignment between two shapes is accomplished efficiently by performing convolution of the corresponding periodic...
