Local Image Descriptors for Matching and Classification Local Image Descriptors for Matching and Classification Title: Local Image Descriptors for Matching and Classification Acknowledgements
This thesis considers view-based object recognition in images, a problem that is still lacking an effective solution despite decades of research in computer vision. It is worth remembering that recognising an object from its appearance is considered as a keystone for image understanding, one of the most challenging problems in computer vision. The study and the analysis of the visual informatio...
متن کاملLearned local descriptors for recognition and matching
In the past local features have become popular for a wide variety of applications such as object recognition, object tracking, structure from motion or stereo vision. Many different interest point detectors as well as local descriptors capturing the information of the local surrounding patches have been proposed. This work investigates the idea of considering keypoint description as a discrimin...
متن کاملAn Evaluation of Local Shape Descriptors in Probabilistic Volumetric Scenes
To simplify the histogram feature computation, we proceed as follows: i) in a first step, for each query point p we compute only the relationships (see Equation 1) between itself and its neighbors – we will call this the Simplified Point Feature Histogram (SPFH); ii) then in a second step, for each point we re-determine its k neighbors and use the neighboring SPFH values to weight the final his...
متن کاملLocal Shape Descriptors, a Survey and Evaluation
Local shape descriptors can be used for a variety of tasks, from registration to comparison to shape analysis and retrieval. There have been a variety of local shape descriptors developed for these tasks, which have been evaluated in isolation or in pairs, but not against each other. We provide a survey of existing descriptors and a framework for comparing them. We perform a detailed evaluation...
