Abstract: Novel systems and methods are described for creating, compressing, and distributing video or image content graded for a plurality of displays with different dynamic ranges. 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.

Abstract: Mixed reality simulation in general, and more specifically to mixed reality simulation devices and systems for training purposes, for example in the medical field, may be provided. For example, a mixed reality simulation method for rendering on a display a mixed reality scenario of a virtual environment adapted to a physical environment, may comprise acquiring, with a sensor, a position of a physical environment object; identifying a mismatch between a physical environment surface and a virtual environment surface, the mismatch depending on the physical environment object position and a mixed reality scenario parameter; and computing a mapping displacement for a virtual environment surface based on the identified mismatch.
