Efficient Image Warping in Parallel for Multiview Three-Dimensional Displays

Three-dimensional (3D) display technologies make great process in recent years. View synthesis for 3D content requires the hole-filling, which is a challenging task. The increase of resolution and the number of views for view synthesis brings new challenges on memory and processing speed. A predicted hole mapping (PHM) algorithm is presented, which requires no filling priority and smoothing operation, allowing parallel computation that facilitates a real-time 3D conversion system. In experiments, the proposed PHM is evaluated and compared with some other methods in terms of peak signal to noise ratio and structural similarity index measurement, and the result shows the advantages in the numbers. The method can operate on the 32-view display with 4K × 2K resolution in real time on GPU.
