-In this paper, we investigate a new approach for personal authentication using Finger-Knuckle-Print through a novel texture descriptor, Local Directional Pattern (LDP). The image is encoded with Local Directional Pattern, which enhances the information as each pixel is represented as a binary LDP code. The Finger-Knuckle-Print is divided into smaller areas and LDP histograms are extracted from...

This paper considers the design of an H∞ controller for tool point control of a hydraulically actuated knuckle boom crane. The paper describes the modelling of the crane’s mechanical and hydraulic systems and a disturbance model. These are linearised and combined in a state-space model used for the controller design. The controller synthesis problem is to design (if possible) an admissible cont...

Injuries to the extensor mechanisms of the fingers can be career-ending in professional athletes if not treated appropriately. We identified 8 professional athletes who underwent 11 direct metacarpophalangeal joint extensor mechanism repairs including centralization of the extensor tendon and sagittal band repair between 1989 and 1994. Success of the operative procedure was determined by the at...

We developed a new approach to investigate how the nervous system activates multiple redundant muscles by studying the endpoint force fluctuations during isometric force generation at a multi-degree-of-freedom joint. We hypothesized that, due to signal-dependent muscle force noise, endpoint force fluctuations would depend on the target direction of index finger force and that this dependence co...

Electronics Letters vol. 45, no. 20, September 2009 Personal Identification using Finger Knuckle Orientation Features Ajay Kumar, Yingbo Zhou This paper proposes a novel approach for personal identification using finger images which exploits the orientation features from the random knuckle lines using finite Radon transform. The feasibility of this approach is rigorously evaluated on a publical...
