A novel Image Retrieval System using an effective region ...
A novel Image Retrieval System using an effective region based shape representation technique ... A variety of methods have been proposed that enable the efficient querying of shape repositories for a desired shape or image. Many of these methods use a sample shape as a query and attempt to retrieve shapes from the database that have a similar ......
A novel technique for content based image retrieval based ...
This paper presents a novel technique for content based image retrieval (CBIR) that selects and assigns weights to the regions of the image on the basis of their contribution to image contents, using a new region-weight assignment scheme. Assigning the weight to each region ignores the irrelevant regions of the image during retrieval and thus maximizes the retrieval accuracy....
 An Efficient and Robust Technique for Region Based Shape ...
In this paper, we propose a novel approach to use contour based method for region based shape representation and retrieval. Specifically, we compute a one dimensional signature function from a region shape and use it for region shape representation and retrieval. We call it polar raster sampling signature or PRS for short. We show that...
An Efficient and Robust Technique for Region Based Shape ...
A simple, fast, robust, invariant and efficient Content Based image Retrieval system with shape signatures derived from skeleton, region and boundary of the object is presented.
Region based Image Indexing and Retrieval System
To overcome the deficiencies of global and grid based methods, Region based image retrieval (RBIR) technique is used. In RBIR system, Image is represented at the object- level by using segmentation method to break image into objects (i.e. homogeneous regions) [6]. It contributes to more...
NOVEL CONTENT –BASED IMAGE RETRIEVAL TECHNIQUES FOR ...
these systems need to consider each region in the database images, resulting in high retrieval response time. Thus, we need a solution to reduce the number of database regions included in the similarity computation. The existing CBIR systems use global features or region based features for representation of image content....
