Latest Patents
Ralf Willenbacher holds a patent titled "Piecewise inter-layer prediction for signals with enhanced dynamic range." This patent focuses on predicting pixel data of a video sequence with enhanced dynamic range (EDR) based on corresponding pixel data from a standard dynamic range (SDR) video sequence. The method utilizes a piecewise inter-layer predictor, which computes output parameters based on at least two sets of pre-computed values and a prediction cost criterion. The first set of values applies to all input SDR frames, while the second set is frame-specific, derived from a histogram of the input SDR frame and pixel values of the corresponding EDR frame. This innovative approach allows for a fast iterative algorithm to identify optimal pivot points for piecewise polynomials, enhancing the efficiency of video processing.
