Polyhedral object recognition by indexing
In computer vision, the indexing problem is the problem of recognizing a few objects in a large database of objects while avoiding the help of the classical image-feature-to-object-feature matching paradigm. In this paper we address the problem of recognizing 3-D polyhedral objects from 2-D images by indexing. Both the objects to be recognized and the images are represented by weighted graphs. ...
متن کاملIndexing without Invariants in 3D Object Recognition
ÐWe present a method of indexing three-dimensional objects from single two-dimensional images. Unlike most other methods to solve this problem, ours does not rely on invariant features. This allows a richer set of shape information to be used in the recognition process. We also suggest the kd-tree as an alternative indexing data structure to the standard hash table. This makes hypothesis recove...
متن کاملObject Recognition Using Color And Geometry Indexing
This thesis addresses the problem in computer vision of recognizing a library of objects in a scene without knowing which objects are in the scene or where they are located. Inherent in this topic is the massive number of possible sets of features from both the scene and the known objects that need to be identified. For an object recognition system to function under these conditions, it must be...
متن کاملPolyhedral Object Recognition with Sparse Data in SIMD Processing Mode
contour, shading and texture, structured light and active range finder measurements. The method ofGrimson, Lozano Perez and others, for the recognition of polyhedral objects with sparse data, has been developed and implemented on a distributed array processor, the AMT DAP 500, which operates in SIMD mode. Measurements involving the location vectors and the surface normals at m data points, cons...
متن کاملModel-based Polyhedral Object Recognition Using Edge-triple Features
While signi cant progress has been made in the computer vision eld over the past decade, and machines capable of performing specialised visual inspection tasks are now being used in many industrial applications, the problem of recognising three-dimensional objects from two-dimensional imagery remains an area of ongoing research. Vision is undoubtedly our most important sense, and solutions to t...
