摘要： The invention concerns a method and a device for correcting distortion errors in a 3D content viewed by an observer on a screen. The method comprises the step of determining a rendered roundness factor (ITO of a pinhole model projected cylinder, estimating a rendered roundness factor table depending on the defined distance of the observer to the screen and the disparity values of objects of the image, determining for the observer a disparity transform function (TD) as a function of the estimated rendered roundness factor table and modifying the object disparity values using the disparity transform so that a perceived roundness factor of one is provided.

摘要： The present disclosure is directed to a method and a device for dealiasing borders in a 3D interpolated view, the interpolated view comprising at least foreground pixels with foreground video in formation and background pixels with background video information. The method comprises the step of detecting, in an interpolated disparity map, associated to the 3D interpolated view, an aliased border between the foreground pixels with a foreground disparity value and the background pixels with a background disparity value, the aliased border delimiting an inner aliased contour formed by foreground pixels and an outer aliased contour formed by background pixel, the aliased border having the form of a stair line; determining a weighting/dealiasing coefficient for each pixel of the outer contour said coefficient corresponding to the part of the pixel area included in the virtual right triangle defined by the two sides of each stair line to the area of the pixel; calculating video information for each pixel of the outer contour in combining the background video information and the foreground video information in a proportion defined by the determined weighting/dealiasing coefficient and replacing video information for each pixel of the outer contour by the calculated video information.

摘要： A method for validating a control operation to be performed by a target device through a virtual control interface. The virtual control interface is displayed by a head mounted device. A selection instruction of a first area is detected, delivering a first area. A position of gaze is detected, delivering a second area within the virtual control interface. It is detected if the first area and the second area are at least partially overlapping a same dedicated area associated to a control operation to be performed by the target device. In case of detection of an occurrence of the first area and the second area at least partially overlapping, the control operation is validated.

摘要： Various implementations provide techniques to prevent excessive parallax, depth, or disparity from being passed through to a viewer. In one particular implementation, it is determined that a depth indicator for an object in a stereoscopic image pair of a video sequence is outside of a target range. One or more images of the stereoscopic image pair is modified so that the depth indicator for the object is within the target range. In other implementations, a depth transition between the object and another portion of the video sequence is smoothed. In further implementations, the stereoscopic image pair is replaced with a 2D image pair that includes the object. In yet further implementations, a resulting video sequence includes (i) one or more stereoscopic image pairs having non-zero disparity and for which the depth indicator is within the target range for the entire image pair, and (ii) one or more 2D image pairs.
