An image processing device may include a disparity map estimator, which may perform an iterative technique to improve the efficiency of generating disparity map. The disparity map estimator performs disparity map refinement using varying size aggregation windows during the first iterations. The disparity map estimator uses larger size aggregation windows during the initial iterations to perform disparity map refinement. Further, the disparity map estimator may use joint bilateral up-sampling during the second (or last) iterations. Using a combination of varying size aggregation windows during the initial iterations and a joint bilateral up-sampling during the second iterations may reduce the computational complexity and memory requirements. In one embodiment, the combination of using varying size aggregation windows and joint bilateral up- sampling to refine the disparity map may reduce the high resolution of the images to a level acceptable for real-time processing and may further reduce the number of incorrect matches. |
