Alongside multitude of innovations and consequential changes in lifestyle, the ability to access home appliances or security cameras over the Internet has been in demand for some years now. In this paper, we propose an efficient, low-cost and user-friendly method to access networked home appliances over the Internet, providing strong, well integrated, three levels of security to the whole application...
We present an efficient algorithm for iris recognition using the variational level set approach and the coalitional game theory. To segment a nonideal iris image accurately, we deploy a variational level set based curve evolution scheme, which uses significantly larger time step for numerically solving the evolution partial differential equation (PDE), and therefore, speeds up the curve evolution...
Moving towards an dasiaalways-onpsila, dasiamobilepsila and technology driven lifestyle, people are demanding greater technical triumph to make life more exciting, convenient and trouble-free. Automation at home has already started catering to this growing need. Another major motivating factor for this is the prospect of higher energy efficiency, greater control on home from remote locations and the...
We propose genetic algorithms to improve the feature subset selection by combining the valuable outcomes from multiple feature selection methods. This paper also motivates the use of asymmetrical SVM, which focuses on two important issues. The first issue is the sample ratio bias, and the second issue is that the different types of misclassification error may have different costs, which lead to different...
We propose an improved iris recognition method to identify the person accurately by using a novel iris segmentation scheme based on the chain code and the collarette area localization. The collarette area is isolated as a personal identification pattern, which captures only the most important areas of iris complex structures, and a better recognition accuracy is achieved. The idea to use the collarette...
Biometric authentication has become increasingly popular in security systems. Recently, the systems based on the human iris, which develops a unique pattern before birth, have produced very high rates of recognition. The iris image is first blurred using a Gaussian filter, and the edge is detected using the Canny edge detection technique. An algorithm, which uses the center of the image as a starting...
This paper presents an efficient iris recognition technique based on the zigzag collarette area localization and asymmetrical support vector machine. The deterministic feature sequence extracted from the iris images using the ID log-Gabor filters is applied to train the support vector machine (SVM). We use the multi- objective genetic algorithm (MOGA) to optimize the features and also to increase...
We propose an improved iris recognition method for person identification using an iris segmentation approach based on chain code and zigzag collarette area with support vector machine (SVM). The zigzag collarette area is selected as a personal identification pattern which captures only the most important areas of iris complex pattern and better recognition accuracy is achieved. The idea to use the...
