Abstract: A device performs a method for tracking an object in a video sequence with a bounding box for display on the device by selecting at least one point that belongs to the object, then motion processing an area of points around the selected at least one point to determine an estimated bounding box; and then color processing the points in the estimated bounding box to determine the bounding box for display on the device. The colour processing comprises computing averages of scores from pixel differences to the background model minus pixel differences from the foreground model per line as long as such average is above a threshold.

Abstract: A particular implementation receives a bitstream and derives parameters from the bitstream. The parameters include quantization parameters, content unpredictability parameters, ratios of lost blocks, ratios of propagated blocks, error concealment distances, motion vectors, durations of freezing, and frame rates. Using these parameters, a compression distortion factor, a slicing distortion factor, and a freezing distortion factor are estimated respectively for distortions resulting from video compression, a slicing mode error concealment, and a freezing slicing mode error concealment. The distortion factors are then mapped to a composite video quality score. For applications with limited computational power, the estimation of distortion factors can be simplified. In particular, the compression distortion factor, the slicing distortion factor, and the freezing distortion factor can be predicted from quantization parameters, ratios of lost blocks, and durations of freezing, respectively.

Abstract: The present disclosure improves 3D representation (by means of adjusting disparity between pictures) in stereoscopic or autostereoscopic images in order to better fit the natural viewing geometry by modifying each image of a stereo pair with a geometric transform centered on an intersection point of an imaging plane and a gaze direction for each of eyes. An observer's view is modeled independently for the left and right eyes, and the left and right views are processed independently with the goal to re-align pixel directions for each of eyes to make these directions more in correspondence with natural vision for the observer.
