An Approach of Likelihood Ratio Score Fusion for Appearance and Shape based Face Recognition
Abstract: AbstractThis paper deals with an approach of likelihood ratio based score fusion technique where appearance and shape based facial features have been used to enhance the efficiency of existing face recognition system. Active Shape Model (ASM) has been used to extract the appearance and shape based facial features. Two different types of features have been used in this work in such a way that when the appearance based feature contains …

Performance Evaluation of DSR, AODV, CGSR based on Average Energy Consumption: A Review
Abstract: AbstractMobile Ad-hoc networks (MANET) have gained lots of attention in researches in recent years, especially in routing protocols due to their dynamic nature. There are number of routing protocols in MANET networks and performance of these routing protocols have been evaluated focusing on metrics such as delay, packet delivery, routing overhead, throughput. However, not much work has been done to evaluate energy aspect of these routing protocols. Design new energy …
