Clustering is a technique that alleviates network congestion and increase the energy efficiency of the Wireless sensor network. Hierarchical clustering and k-means clustering are well established clustering algorithms. The convergence of hierarchical clustering is only based on the inconsistency criterion while the k-means clustering requires the number of(More)
Assigning a label pertaining to an image belonging to its category is defined as object taxonomy. In this paper, we propose a transform based descriptor which effectively extracts intensity gradients defining edge directions from segmented regions. Feature vectors comprising color, shape and texture information are obtained in compressed and de-correlated(More)
