This document presents a new algorithm for content-based image retrieval (CBIR) based on graph cut theory and local binary patterns (LBP). The algorithm extracts nine LBP histograms from each image as features by comparing each pixel in a 3x3 pattern to the other pixels using graph cut theory. Two experiments on texture databases show the proposed Graph Cut Local Binary Patterns (GCLBP) algorithm achieves significantly better retrieval accuracy than LBP and other transform-based methods, as measured by average retrieval precision and rate.
