A hierarchical scheme for elastic graph matching applied to hand gesture recognition is proposed. The proposed algorithm exploits the relative discriminatory capabilities of visual features scattered on the images, assigning corresponding weights to each feature. A boosting algorithm is used to determine the structure of the hierarchy of a given graph. The(More)
BACKGROUND The standard practice in the operating room (OR) is having a surgical technician deliver surgical instruments to the surgeon quickly and inexpensively, as required. This human "in the loop" system may result in mistakes (eg, missing information, ambiguity of instructions, and delays). OBJECTIVE Errors can be reduced or eliminated by integrating(More)
While surgeon-scrub nurse collaboration provides a fast, straightforward and inexpensive method of delivering surgical instruments to the surgeon, it often results in "mistakes" (e.g. missing information, ambiguity of instructions and delays). It has been shown that these errors can have a negative impact on the outcome of the surgery. These errors could(More)
Colloidal gold nanoparticles were used to develop a simple microfluidics-based bioassay that is able to recognize and detect specific DNA sequences via conformational change-induced fluorescence quenching. In this method, a self-assembled monolayer of gold nanoparticles was fabricated on the channel wall of a microfluidic chip, and DNA probes were bonded to(More)
Complex decision making scenarios require maintaining high level of concentration and acquiring knowledge about the context of the task in hand. Focus of attention is not only affected by contextual factors but also by the way operators interact with the information. Conversely, determining optimal ways to interact with this information can augment(More)
