Producing Object-Based Special Visual Effects by Integrating Multiple Differently Focused Images: Implicit 3D Approach to Image Content Manipulation

Kiyoharu Aizawa, Kazuya Kodama, Akira Kubota

Abstract: We propose a novel approach to image content manipulation. It enables us to arbitrarily manipulate an object in a scene by linear processings such as blurring, enhancement and shift etc. Notably, the method does not need any segmentation nor 3D modeling. Making use of multiple differently focused images and a linear imaging model, it directly generates the desired image from the original images. A special camera is developed which can acquire three differently focused image sequences, in order to extend the proposed method to image sequence processing.
