Abstract: Systems and computer-readable medium are disclosed for automatic white balancing of an input image. Accordingly, the system includes a cast detector configured to receive and classify an input image based at least in part on a selection of constituent pixels of the input image. The cast detector is further configured to select the constituent pixels based on a computed reliability of each of the constituent pixels to convey at least one characteristic of a capture illuminant. The system further includes a cast balancer. The cast balancer is configured to perform white balancing of the input image based on the classification of the input image by the cast detector. The cast balancer is further configured to identify the capture illuminant based on at least one characteristic represented by each of the selected constituent pixels.

Abstract: In one example embodiment, a method enables, computing, for a first pixel in the digital mosaiced image, the first pixel being characterized by a first color component and a first set of gradient values in a plurality of orientations, gradient values in the plurality of orientations for a second pixel in the neighborhood of the first pixel. Color values in the plurality of orientations corresponding to a second color component associated with the first pixel based on the set of first gradient values are estimated. The first set of gradient values based at least in part on the computed gradient values is updated. One of the plurality of orientations of the estimated color value based on the updated set of first gradient values is selected and one of the estimated color values corresponding to the selected orientation is determined.

Abstract: A simulated lung for use in real time simulated medical procedures comprising a positive pressure source of a gas, a vacuum pressure source, a fixed interior volume vessel having an inlet, an outlet, and a breath passage port, the inlet in communication with the positive pressure source, and the outlet in communication with the vacuum pressure source, a first flow valve intermediate the positive pressure source and the inlet, a second flow valve intermediate the vacuum pressure source and the outlet, a pressure sensor in communication with the interior volume of the vessel, and means for continuously evaluating a pressure signal generated by the pressure sensor to a desired pressure level within the vessel during the breathing cycle such that a flow of gas entering and exiting the breath passage port of the vessel is synchronized with a predetermined desired flow rate of breathing during the breathing cycle.
