Abstract:
A multi-resolution color image segmentation algorithm which takes advantage of gradient information in an adaptive and progressive framework is described. A gradient-based segmentation method is initiated with a dyadic wavelet decomposition scheme of an arbitrary input image, accompanied by a vector gradient calculation of its color converted counterpart. The resultant gradient map is used to automatically and adaptively generate thresholds for segregating regions of varying gradient densities, at different resolution levels of the input image pyramid. In combination with a confidence map and non-linear spatial filtering techniques, regions of high confidence are passed from one resolution level to another until the final segmentation at highest (original) resolution is achieved.
Abstract:
A system and method for multi-spectral image capture of a first scene includes acquiring a first series of images of the first scene with one or more image acquisition systems and filtering each of the first series of images of the scene with a different non-interference filter, illuminating each image of the first series of images with a different illuminant, or acquiring each of the images of the first series of images with a different image acquisition system. Each of the image acquisition systems has at least one color channel, each of the non-interference filters has a different spectral transmittance, and each of the illuminants has a different spectral power distribution.
Abstract:
A multimedia capture system includes a plurality of imaging systems and one or more detection systems. The plurality of imaging systems capture image areas of a scene from at least partially different locations. The one or more detection systems determine a relative position of each of the plurality of imaging systems with respect to the different locations of the scene from where the image areas are captured. The relative position of each of the plurality of imaging systems and the captured image areas are used to generate a multimedia presentation of the scene. The capture system may be worn by an individual or may be on a stationary or mobile support.
Abstract:
An alpha voltaic battery includes at least one layer of a semiconductor material comprising at least one p/n junction, at least one absorption and conversion layer on the at least one layer of semiconductor layer, and at least one alpha particle emitter. The absorption and conversion layer prevents at least a portion of alpha particles from the alpha particle emitter from damaging the p/n junction in the layer of semiconductor material. The absorption and conversion layer also converts at least a portion of energy from the alpha particles into electron-hole pairs for collection by the one p/n junction in the layer of semiconductor material.

Abstract:
A multimedia presentation system includes a plurality of display systems and at least one control system. The plurality of display systems output image areas of a multimedia presentation to at least partially different locations of a display environment. The control system adjusts the output of the image areas from the plurality of display systems to conform to the display environment. The display and capture systems may be wearable, mobile or adjustable and can react to any environment. Editing environments allow the same show to be easily relinked to a new display configuration without any need for extensive user-driven layout revision. Virtual display configurations are simulated and presented on other displays.

A micro-electro-mechanical switch includes at least one portion of a conductive line in the chamber, a beam with imbedded charge, and control electrodes. The beam has a conductive section which is positioned in substantial alignment with the at least one portion of the conductive line. The conductive section of the beam has an open position spaced away from the at least one portion of the conductive line and a closed position on the at least one portion of the conductive line. Each of the control electrodes is spaced away from an opposing side of the beam to control movement of the beam.

A disinfection system and method includes a reactor with a chamber and at least one radiation source. The chamber in the reactor has at least one inlet that is oriented to generate a vortex motion for a fluid introduced to the chamber. The radiation source is positioned to be offset from an axis which extends along a center of the chamber of the reactor. The radiation source at least partially directs radiation towards a circulating flow of the fluid in the chamber from the vortex motion in at least a gap between a wall of the chamber of the reactor and the at least one radiation source.
