Non-Linear Aperture for Stylized Depth of Field
We introduce in this paper non-linear apertures that produce stylized depth of field from lightfield data. A non linear aperture is similar in spirit to the conventional aperture of a camera, except that it replaces the blur of shallow depth of field by a more complex detail removal filtering. The resulting non-realistic apertures produce stylized images where the amount of abstraction varies automatically with depth.
