This document summarizes an article that proposes using color histogram processing to improve the efficiency of content-based image retrieval (CBIR) systems. It describes computing feature vectors for global descriptor attributes to characterize images prior to calculating color histograms, in order to reduce computation time and make the CBIR system more efficient. The performance of using global descriptor attributes and color histograms for image retrieval is evaluated and results are presented. While this approach shows some improved performance over prior methods, the authors conclude that further modifications are still needed to optimize image search capabilities.
