This document describes a content-based image retrieval system using features extracted from error diffusion block truncation coding (EDBTC). EDBTC produces color quantizers and a bitmap image, which are vector quantized to generate features for image matching - a color histogram feature and a bit pattern histogram feature. These features are used to measure similarity between a query image and images in a database. The proposed approach outperforms other content-based image retrieval methods on natural and textural image datasets. Hardware and software requirements for implementing the system are also provided, along with the project workflow.

Title: Content-Based Image Retrieval Using Error
Diffusion Block Truncation Coding Features
Abstract—This paper presents a new approach to index color images using the
features extracted from the error diffusion block truncation coding (EDBTC). The
EDBTC produces two color quantizers and a bitmap image, which are further
processed using vector quantization (VQ) to generate the image feature descriptor.
Herein two features are introduced, namely, color histogram feature (CHF) and bit
pattern histogram feature (BHF), to measure the similarity between a query image
and the target image in database. The CHF and BHF are computed from the VQ-
indexed color quantizer and VQ-indexed bitmap image, respectively. The distance
computed from CHF and BHF can be utilized to measure the similarity between
two images. As documented in the experimental result, the proposed indexing
method outperforms the former block truncation coding based image indexing and
the other existing image retrieval schemes with natural and textural data sets. Thus,
the proposed EDBTC is not only examined with good capability for image
compression but also offers an effective way to index images for the contentbased
image retrieval system.
