The objective of the paper is to present an efficient Content-Based Retrieval (CBIR) using Ordered-Dither Block Truncation Coding Technique (ODBTC). During the encoding stage, ODBTC approach compresses the image block(s) into quantizes and bitmap image, respectively. To index an image, two features are proposed, which are the Color Co-occurrence Feature (CCF), and Bit Pattern Feature (BPF). Experimental results concluded that the proposed method outperformed the Block Truncation Coding (BTC) approach-based image retrieval systems, thus proving that ODBTC scheme is an effective descriptor to index the database images for efficient retrieval in the CBIR system.
