Virtual view generation by linear processing of two differently focused images

Presents a method to render shifting (parallax) and focusing effects on object in a scene for generating a virtual view image with arbitrary focus. Two differently focused images of a same scene-near-focused image and far-focused image-are used as input images under the assumption that a scene has near and far objects. The proposed method can freely handle the shifting and the focusing effect on each object according to the view point and the focus depth of the virtual camera only by linear filtering of the input images without any segmentation or 3D modeling of the objects. Experimental results using real images are shown to test the performance of the method.
