چکیده

The color histogram has played an important role on pattern recognition, image indexing, and many other applications. One of the major obstacles for applying color histograms is the intimidating storage and computational requirements due to its high dimension nature. In contrast to the conventional multi-valued color histogram, we propose a simplified binary color histogram in the HSV color space for image indexing. Similarity calculation can therefore be made using the Hamming metric. Preliminary experimental results show that good retrieval performance can be achieved with the proposed scheme. Further improvements by adaptive thresholding are currently under development.

An efficient color representation for image retrieval

A compact color descriptor and an efficient indexing method for this descriptor are presented. The target application is similarity retrieval in large image databases using color. Colors in a given region are clustered into a small number of representative colors. The feature descriptor consists of the representative colors and their percentages in the region. A similarity measure similar to th...

Content 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...

Fast indexing: a comparative evaluation

In this evaluation the efficiency of three image signature called angular spectrum, Hough based signature and color histogram are tested The first signature is intrinsic hierarchical (deriving from image frequency spectrum) and than non signature space reduction technique is used. The second is a short signature directly indexed and the last (color histogram) need to be reduced for fast indexin...

Grouping and Indexing Color Features for Efficient Image Retrieval

Content-based image retrieval (CBIR) aims at searching image databases for specific images that are similar to a given query image based on matching of features derived from the image content. This paper focuses on a low-dimensional color based indexing technique for achieving efficient and effective retrieval performance. In our approach, the color features are extracted using the mean shift a...

An efficient low-dimensional color indexing scheme for region-based image retrieval

In this work, an efficient low-dimensional color indexing scheme for region-based image retrieval is presented. The colors in each image region are first quantized so that only a small number of cluster centroids are needed to represent the region color information. The proposed color feature descriptor consists of these quantized colors and their percentages in the region. A similarity distanc...
