A Robust CBIR Approach Using Local Color Histograms
Technical report TR01-13. Global color histograms are well-known as a simple and often way to perform color-based image retrieval. However, it lacks spatial information about the image colors. The use of a grid of cells superimposed on the images and the use of loca l color histograms for each...
Cell Histograms Versus Color Histograms for Image Representation and Retrieval
Technical report TR01-01. Color is a commonly used feature for realizing content-based image retrieval (CBIR). In this context, this paper presents a new approach for CBIR which is based on well known and widely used color histograms. Previous approaches have used a single global color...
Color Based Image Retrieval Using Signature Trees
Technical report TR01-02. Significant research has focused on determining efficient methodologies for effective and speedy retrieval in large image databases. Towards that goal, the first contribution of this paper is an image abstraction technique, called VBA, based on signature bit-strings and...
Color-Based Image Retrieval Using Compact Binary Signatures
Technical report TR01-08. Significant research has focused on determining efficient methodologies for retrieving images in large image databases. This thesis addresses the design and implementation of a new image abstraction technique based on compact signature bit-strings and an appropriate...
