In implementations, the created content is “continuous dynamic range” (CDR) content—a novel representation of pixel-luminance as a function of display dynamic range. The creation of the CDR content includes grading a source content for a minimum dynamic range and a maximum dynamic range, and defining a luminance of each pixel of an image or video frame of the source content as a continuous function between the minimum and the maximum dynamic ranges. In additional implementations, a novel graphical user interface for creating and editing the CDR content is described.Type: GrantFiled: September 22, 2015Date of Patent: July 9, 2019Assignees: Disney Enterprises, Inc., Eidgenoessische Technische Hochschule Zurich (ETH Zurich)Inventors: Aljoscha Smolic, Alexandre Chapiro, Simone Croci, Tunc Ozan Aydin, Nikolce Stefanoski, Markus Gross

Patent number: 10229517Abstract: In a method and apparatus for segmentation of an examination region to be imaged, scan projection data are acquired from the examination region to be mapped. Iterative reconstruction takes place on the basis of the acquired scan projection data. Preliminary image data and preliminary textural features are reconstructed. Anticipated preliminary structures, preferably preliminary contours, are determined in the examination region on the basis of the obtained preliminary textural features. The anticipated preliminary structures are then taken into account during iterative reconstruction of preliminary image data and preliminary textural features. An image segmentation method is described, moreover. An image reconstruction device is also described.Type: GrantFiled: December 22, 2016Date of Patent: March 12, 2019Assignee: Siemens Healthcare GmbHInventors: Rainer Raupach, Grzegorz Soza

Patent number: 10212312Abstract: Methods of image calibration and in particular of image calibration having a multiple of color scales as well as to quantitative imaging such as quantitative medical imaging, or to a display device or to a system for displaying an image, or to a controller of a display, or to software to enable the image calibration, or to a visualization application and a display. The method for processing an image, includes the steps of: —selecting at least one trajectory in a color space; —defining a transformation which primarily increases perceptual linearity of consecutive points belonging to the at least one trajectory; —applying the transformation to the image. This has the advantage that the perceptual linearity can be restricted to the trajectory.Type: GrantFiled: July 10, 2015Date of Patent: February 19, 2019Assignee: BARCO NVInventor: Tom Kimpe

Patent number: 10032262Abstract: A processor for signal reshaping receives an input image with an input bit depth. Block-based standard deviations are computed. The input codewords are divided into codeword bins and each bin is assigned a standard deviation value. For each bin, a standard deviation to bit-depth function is applied to the bin values to generate minimal bit depth values for each codeword bin. An output codeword mapping function is generated based on the input bit depth, a target bit depth, and the minimal bit depth values. The codeword mapping function is applied to the input image to generate an output image in the target bit depth.Type: GrantFiled: January 27, 2017Date of Patent: July 24, 2018Assignee: Dolby Laboratories Licensing CorporationInventors: Amin Kheradmand, Guan-Ming Su, Cheng-Chi Li

Patent number: 9997134Abstract: Methods and systems for calibrating devices reproducing high dimensional data, such as calibrating High Dynamic Range (HDR) displays that reproduce chromatic data. Methods include mapping input data into calibrated data using calibration information retrieved from spatial data structures that encode a calibration function. The calibration function may be represented by any multidimensional scattered data interpolation methods such as Thin-Plate Splines. To efficiently represent and access the calibration information in runtime, the calibration function is recursively sampled based on guidance dataset. In an embodiment, an HDR display may be adaptively calibrated using a dynamic color guidance dataset and dynamic spatial data structures.Type: GrantFiled: February 2, 2015Date of Patent: June 12, 2018Assignee: DISNEY ENTERPRISES, INC.Inventors: Aljosa Smolic, Nikolce Stefanoski, Tunc Ozan Aydin, Jing Liu, Anselm Grundhofer
