Image Retrieval using Canopy and Improved K mean Clustering

چکیده
In a typical content based image retrieval (CBIR) system, target images are sorted by feature similarities with respect to the query. These methods fail to capture similarities among target images and user feedback. To overcome this problem existing methods combine relevance feedback and clustering. But clustering requires more number of expensive distance calculations. To remedy this problem we propose a new technique that combine canopy method, relevance feedback and improved k mean clustering. Canopy method reduces expensive distance calculation by measuring exact distances between points that occur in a common canopy. Improved k mean clustering automatically compute number of cluster and uses max min distance to reduce computational complexity. Relevance feedback captures exact user interest. The experiments show that our method is highly effective for image retrieval..

A Novel Method for Content Base Image Retrieval Using Combination of Local and Global Features
Content-based image retrieval (CBIR) has been an active research topic in the last decade. In this paper we proposed an image retrieval method using global and local features. Firstly, for local features extraction, SURF algorithm produces a set of interest points for each image and a set of 64-dimensional descriptors for each interest points and then to use Bag of Visual Words model, a cluster...

Image segmentation is a fundamental step in many of image processing applications. In most cases the image’s pixels are clustered only based on the pixels’ intensity or color information and neither spatial nor neighborhood information of pixels is used in the clustering process. Considering the importance of including spatial information of pixels which improves the quality of image segmentati...
