Abstract: A display system comprises a color sequential display (201) having a backlight (205) comprising several backlight segments and a light modulating panel (207) comprising pixels having controllable light transmission. A backlight unit (211) determines, for a plurality of backlight segments, backlight chromaticities for fields of an image in response to the image content.

Abstract: A methodology is provided for correcting the placement of a laser beam's focal point. Specifically, this correction is done to compensate for displacements of the focal point that may be caused when implant material (e.g. an Intraocular Lens (IOL)) is positioned on the optical path of the laser beam. The methodology of the present invention then determines a deviation of the laser beam's refracted target position (uncompensated) from its intended target position. A calculation of the deviation includes considerations of the laser beam's wavelength and refractive/diffractive characteristics introduced by the implant material. This deviation is then added to the refracted target position to make the refracted target position coincide with the intended target position of the focal point. The laser beam will then focus to its intended target position.

Abstract: A method is provided for localizing parts of an object in an image by training local detectors using labeled image exemplars with fiducial points corresponding to parts within the image. Each local detector generates a detector score corresponding to the likelihood that a desired part is located at a given location within the image exemplar. A non-parametric global model of the locations of the fiducial points is generated for each of at least a portion of the image exemplars. An input image is analyzed using the trained local detectors, and a Bayesian objective function is derived for the input image from the non-parametric model and detector scores. The Bayesian objective function is optimized using a consensus of global models, and an output is generated with locations of the fiducial points labeled within the object in the image.
