With the availability of internet technology and the low-cost of digital image sensor,
enormous amount of image databases have been created in different kind of applications …

In this paper, we propose a novel image indexing and retrieval algorithm using local tetra
patterns (LTrPs) for content-based image retrieval (CBIR). The standard local binary pattern …

In this paper, a new image indexing and retrieval algorithm using local mesh patterns are
proposed for biomedical image retrieval application. The standard local binary pattern …

A new algorithm meant for content based image retrieval (CBIR) and object tracking
applications is presented in this paper. The local region of image is represented by local …

A new set of two-dimensional (2-D) rotated complex wavelet filters (RCWFs) are designed
with complex wavelet filter coefficients, which gives texture information strongly oriented in …

In this paper, a new algorithm using directional local extrema patterns meant for content-
based image retrieval application is proposed. The standard local binary pattern (LBP) …

Similarity metrics plays an important role in content-based image retrieval. The paper
compares nine image similarity measures-Manhattan (L1), weighted-mean-variance (WMV) …

A novel approach for texture image retrieval is proposed by using a new set of two-
dimensional (2-D) rotated wavelet filters (RWF) and discrete wavelet transform (DWT) jointly …

In the recent years the rapid growth of multimedia content makes the image retrieval a
challenging research task. Content Based Image Retrieval (CBIR) is a technique which uses …

This paper proposes a novel approach for rotation-invariant texture image retrieval by using
set of dual-tree rotated complex wavelet filter (DT-RCWF) and DT complex wavelet transform …
