Multidimensional Spectral Hashing
With the growing availability of very large image databases, there has been a surge of interest in methods based on “semantic hashing”, i.e. compact binary codes of data-points so that the Hamming distance between codewords correlates with similarity. In reviewing and comparing existing methods, we show that their relative performance can change drastically depending on the definition of ground...
متن کاملMultibiometric Database Retrieval Method Based on Index Code
Multibiometrics use of multiple biometric sources for human recognition, mitigates some of the limitations of unimodal biometric systems by increasing recognition accuracy, imparting fault-tolerance, and enhancing security. These databases are used extensively, thereby requirement of efficient technique for searching and retrieving relevant identities from large biometric database. Searching ou...

متن کاملRetrieval by Shape Using Multidimensional Indexing Structures
In modern visual information retrieval systems, visual content is directly addressed by features such as color, texture, shape and spatial relationship. While a large work is being done around the perceptual soundness of models and around the automatic extraction of features, only a limited attention is placed on the combination of useful representations and similarity models with efficient ind...
متن کاملContent Based Radiographic Images Indexing and Retrieval Using Pattern Orientation Histogram
Introduction: Content Based Image Retrieval (CBIR) is a method of image searching and retrieval in a database. In medical applications, CBIR is a tool used by physicians to compare the previous and current medical images associated with patients pathological conditions. As the volume of pictorial information stored in medical image databases is in progress, efficient image indexing and retri...
