Abstract

In this sketch, we present a novel approach to image-based rendering (IBR) techniques for generating a virtual view image from different positions with arbitrary focus using two differently focused images captured from a fixed position. In the conventional approach [Potmesil and Chakravarty 1981], focus blur have been produced by applying a realistic camera model to given 3D objects. We propose here a much simpler and more effective method only using space-invariant filters to render both parallax and focusing effects on objects in a scene, according to the virtual camera's position and focus depth respectively. The proposed method does not need any segmentation and 3D modeling.

Abstract
Estimating 3D surface normals through photometric stereo has been of great interest in computer vision research. Despite the success of existing traditional and deep learning-based methods, it is still challenging due to: (i) the requirement of ...
