Item Fabric Inspection using Gradient Space and its Energy(2015-11-27T06:59:40Z) Asha, V; Bhajantri, N U; Nagabhushan, PIn this paper, we propose a machine vision algorithm for fabric inspection in patterned textures with the help of gradient space obtained using Newton’s forward difference scheme and its energy. Gradient space image is obtained from the input defective image and is split into several blocks of size same as that of the periodic unit of the input defective image. Energy of the gradient space image is used as input feature space for identifying defective and non defective periodic blocks using Ward’s hierarchical clustering. Experiments on real fabric images with defects show that the proposed method can be used for automatic detection of fabric defects in textile industriesItem owards Performance Improvement of Cloud Applications under Virtualized Environment using PSO based K-means++ Algorithm(2015-11-27T06:06:50Z) Nirmala, A.P.; Sridaran, RVirtualization generally provides performance isolation between virtual machines running simultaneously on a single physical machine. But isolation does not happen to its fullest extent which may lead to performance interference. Due to this, the performance of applications running on one VM may get affected by running applications of co-existing VMs. This further leads to delay in execution time. As a result of this, throughput of cloud applications will be degraded. In order to deal with this situation, the proposed work has been presented which uses Particle Swarm Optimization based k-means++ algorithm for its implementation. The proposed work has been compared with some of the existing approaches and found to have better throughput and reduction in run time and cost.
