A novel facial expression recognition method using bi-dimensional EMD based edge detection 2010 2273 Facial expressions provide an important channel of nonverbal communication. Facial recognition techniques detect people’s emotions using their facial expressions and have found applications in technical fields such as Human-Computer-Interaction (HC...
Performance analysis of ultra wideband communication systems 2011 1731 Ultra Wideband (UWB) radio is one of the emerging technologies which have promising characteristics such as high data rate transmission, material penetration, multiple access capability and reduced fading. It has the potential to evolve as the future...
Activity recognition using Grey-Markov model 2011 477 Activity Recognition (AR) is a process of identifying actions and goals of one or more agents of interest. AR techniques have been applied to both large and small scale activity identification. Examples of AR techniques include Genetic Algorithm, M...
Timing synchronization in MIMO-OFDM systems 2013 13222 OFDM (Orthogonal Frequency Division Multiplexing) provides a promising physical layer for 4G and 3GPP LTE Systems in terms of efficient use of bandwidth and high data rates. It is used in several applications likeWiFi (IEEE 802.11n),WiMax (IEEE 802...
Network traffic anomaly detection using EMD and Hilbert-Huan transform 2013 1052 Empirical Mode Decomposition (EMD) and Hilbert-Huang Transform (HHT) provide a means for adaptive data analysis. EMD extracts Intrinsic Mode Functions (IMFs) that represent the frequency and amplitude characteristics of a signal. HHT generates the ...
