— Brain-mapping techniques have proven to be vital in understanding the molecular, cellular, and functional mechanisms of the brain. Normal anatomical imaging can provide structural information on certain abnormalities in the brain. However there are many neurological disorders for which only structure studies are not sufficient. In such cases it is(More)
Dental biometric system is used to identify deceased individual. Dental biometric system is used in forensic science. In this system AM radiograph is matched with PM radiograph to identify unidentified individual. Dental biometrics consists of four steps as: preprocessing of dental radiograph, segmentation, feature extraction and matching of AM and PM(More)
— Action, cognition, emotion and perception can be mapped in the brain by using set of techniques. Translating unimodal concepts from one modality to another is an important step towards understanding the neural mechanisms. This paper provides a comprehensive survey of multimodal analysis of brain signals such as fMRI, EEG, MEG, NIRS and motivations,(More)
To understand 'Working of Human Brain', measurements related to the brain function are required. These measurements should be possibly non-invasive. Brain should be disturbed as less as possible during the measurement. Integration of various modalities plays a vital role in understanding the cognitive and the behavioral changes in the human brain. It is an(More)
Modern work requires multitasking and the need for sustained vigilance, which result in work-related stress and increase the possibility of human error. So methods for estimating cognitive overload and mental fatigue of the brain during work performance are needed. Cognitive load (CL) refers to the amount of mental demand imposed by a task on a person, and(More)
Osteoporosis is characterized by compromised bone strength and is considered to be a silent disease that entails significant social and economic burdens. This disease causes reduction in weight and bone fractures. Dual X-ray Absoptiometry i.e. DXA is the commonly used technique to determine Bone Mineral Density. The high cost and limited availability of DXA(More)
The method for estimating reduced bone mineral density from dental radiographs is discussed in this paper. Dual X-ray absorptiometry is the common technique to determine bone mineral density. Because of high costs and limited availability, it is worthwhile to look for alternative diagnostic techniques. The objective of this study was to investigate the use(More)
