A correlogram algorithm for image indexing and retrieval using wavelet and Rotated Wavelet Filters

TLDR
The proposed image-indexing algorithm with the combination of wavelet and Rotated Wavelet Correlogram is six times faster than the GWC, which make it suitable for online application.
Abstract
In this paper, a new image-indexing algorithm with the combination of wavelet and Rotated Wavelet Correlogram (RWC) is proposed in contrast to the Gabor Wavelet Correlogram (GWC) The 0° and 90° information (sub-band) of image collected from Standard Wavelet Filters (SWFs) and +45° and −45° are collected from Rotated Wavelet Filters (RWFs) and further used for correlogram feature calculation The data handling with proposed method is very less compared with GWC therefore this method is six times faster than the GWC, which make it suitable for online application The retrieval results of the proposed method are tested on three different databases, ie, Corel 1000 (DB1) natural image database, MIT VisTex (DB2) texture image database and Corel 2450 (DB3) natural image database The results after being investigated show a significant improvement in terms of their evaluation measures as compared with most of existing techniques on respective databases

Local Gabor maximum edge position octal patterns for image retrieval

TL;DR: A new feature descriptor, octal code which is coded based on the maximum edge positions (MEP) on Gabor responses is proposed, which shows a significant improvement as compared to other existing methods in terms of average retrieval precision (ARP) and average retrieval rate (ARR) on Corel-5000 andCorel-10000 databases.

A hierarchical CBIR framework using adaptive tetrolet transform and novel histograms from color and shape features

TL;DR: A three-level hierarchical CBIR system/framework where, each level of the hierarchy uses either texture, shape or color image features to reduce the size of the image database by discarding the irrelevant images and at final level ofThe hierarchy, it will extract the most analogous images from the reduced image database.

Visual pattern recognition by moment invariants

TL;DR: It is shown that recognition of geometrical patterns and alphabetical characters independently of position, size and orientation can be accomplished and it is indicated that generalization is possible to include invariance with parallel projection.

The contourlet transform: an efficient directional multiresolution image representation

TL;DR: A "true" two-dimensional transform that can capture the intrinsic geometrical structure that is key in visual information is pursued and it is shown that with parabolic scaling and sufficient directional vanishing moments, contourlets achieve the optimal approximation rate for piecewise smooth functions with discontinuities along twice continuously differentiable curves.

Similarity of color images

TL;DR: Two new color indexing techniques are described, one of which is a more robust version of the commonly used color histogram indexing and the other which is an example of a new approach tocolor indexing that contains only their dominant features.

Comparing images using color coherence vectors

TL;DR: It is shown that CCV’s can give superior results to color histogram-based methods for comparing images that incorporates spatial information, and to whom correspondence should be addressed tograms for image retrieval.
