Directional line edge binary pattern for texture image indexing and retrieval

Abstract

In this paper, a new method, directional line edge binary pattern (DLEBP) is proposed for image indexing and retrieval. This method is the extension of line edge binary pattern (LEBP). The directional line edges of neighbours for a particular center pixel are determined by eight directional windows. The 3×3 directional window is considered for this purpose. The retrieval results of the proposed method are tested on Brodatz image database. The performance of the proposed method is measured in terms of average retrieval rate (ARR). The results after being investigated show a significant improvement in terms of ARR as compared to Gabor transform (GT), dual-tree complex wavelet transform (DT-CWT), dual-tree rotated complex wavelet transform (DT-RCWT), local ternary pattern (LTP), LEBP and local binary pattern (LBP). KeywordsContent based image retrieval (CBIR), line edge binary pattern (LEBP), local binary pattern (LBP) and directional line edge binary pattern (DLEBP).
