Clustering, a well-known technique, is used to divide a data set into number of groups, called clusters. Differential evolution and particle swarm optimization are robust, fast and very effective search techniques. To increase computational capability, two different quantum inspired meta-heuristics for automatic clustering, have been proposed here. An application of quantum inspired techniques has...
Clustering is a simple technique to make partition of given data set into number of clusters. This paper presents an quantum inspired algorithm using GA to automatically find the number of clusters for image data set. The advantage lies in this technique is that no previous information about the data set used for classification is required before hand. The method decides the optimum cluster number...
Static video summarization techniques aim to represent the salient content in a video by extracting a set of key-frames for presentation to the user. An efficient key-frame extraction process is thus vital for effective video summarization, browsing and indexing in content-based video retrieval systems. In this paper, a three phased approach for key-frame extraction is proposed which aims to represent...
Shot segmentation is an important preprocessing step towards content based video analysis. In this paper, we propose a Spatio-Temporal Fuzzy Hostility Index (STFHI) for determining the edges of objects present in the frames, composing the video. The edges present in the frames are treated as features of the frame. The correlation between the features is computed for successive frames of the video...
A multilevel gray scale image can quite efficiently be segmented by the multilevel sigmoidal (MUSIG) activation function based on equal and fixed class responses, ignoring the heterogeneity of image information content. The optimized version of MUSIG (OptiMUSIG) activation function can be generated with the optimized class responses from the image content and can be used effectively to segment the...
