Image Retrieval by Colour and Texture Using Chromaticity Histograms and Wavelet Frames
نویسندگان
چکیده
In this paper the combination of texture and colour features is used for image classi cation. Texture features are extracted using the Discrete Wavelet Frame analysis. 2-D or 1-D histograms of the CIE Lab chromaticity coordinates are used as colour features. The 1-D histograms of the a; b coordinates were also modeled according to the generalized Gaussian distribution. The similarity measure de ned on the features distribution is based on the Bhattacharya distance. Retrieval benchmarking is performed on textured colour images from natural scenes, obtained from the VisTex database of MIT Media Laboratory and from the Corel Photo Gallery.

Introduction: Content Based Image Retrieval (CBIR) is a method of image searching and retrieval in a database. In medical applications, CBIR is a tool used by physicians to compare the previous and current medical images associated with patients pathological conditions. As the volume of pictorial information stored in medical image databases is in progress, efficient image indexing and retri...

An Efficient Image Retrieval Based on Fusion of Fast Features and Query Image Classification
Content Based Image Retrieval (CBIR) is an emerging research area in computer vision, in which, we yield similar images as per the query content. For the implementation of CBIR system, feature extraction plays a vital role, where colour feature is quite remarkable. But, due to unevenly colored or achromatic surfaces, the role of texture is also important. In this paper, an efficient and fast CB...
متن کاملImage Retrieval Based on Colour and Nonlinear Texture Invariants
Among other techniques especially methods working fully automatically are of interest for image retrieval from large databases. Colour histograms proved to be successful in automatic image retrieval, however, their drawback is that all structural information is lost. Therefore we extend the colour histogram approach by features that take into account the relations within a local pixel neighbour...
متن کاملLow-Level Features for Image Retrieval Based on Extraction of Directional Binary Patterns and Its Oriented Gradients Histogram
In this paper, we present a novel approach for image retrieval based on extraction of low level features using techniques such as Directional Binary Code (DBC), Haar Wavelet transform and Histogram of Oriented Gradients (HOG). The DBC texture descriptor captures the spatial relationship between any pair of neighbourhood pixels in a local region along a given direction, while Local Binary Patter...
