We present variable-aperture photography, a new method for analyzing sets of images captured with different aperture settings, with all other camera parameters fixed. We show that...
In the paper, we describe an optical system which is capable of providing external access to both the sensor and the lens aperture (i.e., projection center) of a conventional came...
Since 1960s, aperture patterns have been studied extensively and a variety of coded apertures have been proposed for various applications, including extended depth of field, defocu...
Computational photography is an emerging field combining smart optics,
electronics, computer vision and graphics. Recent trends in enhancing the
capabilities of a camera involve ...
