Prior research evidenced that the unimodal biometric systems have several tradeoffs like noisy data, intra-class variations, restricted degrees of freedom, non-universality, spoof attacks, and unacceptable error rates. In order for the biometric system to be more secure and to provide higher accuracy, more than one form of biometrics are required. Hence,(More)
A new features extraction algorithms for G-banded chromosomes classification system based on neural networks, fuzzy rule based and template matching classifiers are proposed. Chromosomes image is acquired and processed, geometrical features and gray-scale features are extracted for 872 chromosomes. Neural networks, fuzzy rule based, template matching(More)

Most bone densitometry ultrasound devices measure only single predefined peripheral skeletal site. We propose a classification system to study the ability of combining speed of sound (SOS) measured at multiple bone sites to differentiate subjects with osteoporosis fractures from normal subjects based on fuzzy logic and neural networks systems.(More)
A free style hand geometry verification system based on geometrical features extracted from the image plan of the hand was proposed, the system extracts features from the hand image without using pegs and verifies the identity of the person. System performance results were finally reported to exceed.
This paper proposes a novel algorithm for speckle reduction in medical ultrasound imaging while preserving the edges with the added advantages of adaptive noise filtering and speed. We propose a nonlinear image diffusion algorithm that incorporates two local parameters of image quality, namely, scatterer density and texture-based contrast in addition to(More)
We propose a path planning simulation system for 3D ultrasound guided needle biopsy, this system is designed to accurately take a 3D biopsy specimen from an abdominal focal lesion without puncturing a blood vessel or pass through ribs, the introduced system traces the 3D position of the biopsy needle and visualizes the needle in 3D and 2D in real time(More)
This paper proposes a new sex classification method from patellae using a novel automated feature extraction technique. A dataset of 228 patellae (95 females and 133 males) was collected and CT scanned. After the CT data was segmented, a set of features was automatically extracted, normalized, and ranked. These features include geometric features, moments,(More)
We propose a system for 4D reconstruction, visualization, measurements and quantification of cardiac parameters. The system is connected with a conventional 2D ultrasound machine via video signal. Images are acquired and registered with electromagnetic position sensor readings and ECG signal readings. Volume reconstruction and volume visualization of the(More)
