摘要： A method for tone mapping a digital image comprised of a plurality of high bit depth intensity values in linear space is disclosed. First, a plurality of liner intensity values are mapped from the linear space to a non-linear space (402). Then a left and a right boundary interval value are determined in the linear space for each of the plurality of high bit depth intensity value (404). A dither pattern is then overlaid onto the plurality of high bit depth intensity values in linear space (406). For each one of the plurality of high bit depth intensity values in linear space, one of the boundary interval values is selected, based on the current high bit depth intensity value, the left and right boundary interval values for the current pixel, and the dither pattern value overlaid onto the current pixel (408). Each of the selected boundary interval values are mapped into a lower bit depth non-linear space (410). And then the mapped selected boundary interval values are stored onto a computer readable medium.

摘要： A reference set of image features is determined from an electronic data file specifying a reference image in a reference coordinate space. Rendering information describing a physical rendering of the reference image is ascertained. Calibration-enabling data is derived from the reference set of the image features and the ascertained rendering information. The calibration-enabling data is provided to calibrate an imaging system. The calibration-enabling data may be stored. The imaging system may capture an image of the physical rendering of the reference image in relation to a capture coordinate space. An extracted set of image features may be extracted from the captured image. Respective ones of the image features in the reference and extracted sets may be matched. The imaging system may be calibrated based on matched ones of the image features and the rendering information.

摘要： An apparatus and method for distributing representative images of a plurality of data objects within a database within a partitioned three-dimensional graphical environment is described. According to the apparatus and method an environment is divided into areas bounded by partitions, and groups of representative images are distributed and displayed upon these partitions. In general, distribution of the representative images is achieved by determining weight factors for each partition bounding a given area and determining weight factors for representative images that are to be displayed within the areas upon the partitions and then distributing the images dependent on the comparison of the image weight factors to partition weight factors.

摘要： Defining a display region for a projector display. An image of a camera's view of a display region is accessed. The image is displayed on a graphical user interface. The image has a first set of coordinates. The image and a reference canvas that is displayed on said graphical user interface is integrated. The integration comprises overlaying a portion of the reference canvas on the image. The reference canvas has a second set of coordinates. One of the first set of coordinates and the second set of coordinates represents a mesh of movable control points being movable from a first location to a second location on the graphical user interface. The first set of coordinates are mapped to the second set of coordinates, thereby generating a pointwise correspondence mapping between coordinate points of the reference canvas and coordinate points of the image.

摘要： A projector is associated with a head gear for a first participant of collaboration. The head gear does not obstruct the participant's eyes. The projector is configured to receive an image which was created with respect to a first participant's view point based on a dataset that represents an object. The projector is configured for projecting the received image onto a display surface. The first participant perceives the projected image by receiving at least a portion of diffused light associated with the projected image at the first participant's eye that is closest to the projector.
