Bokeh effects based on stereo vision


by D Liu, R Nicolescu, R Klette
Abstract:
Bokeh, a sought-after photo rendering style of out-of-focus blur, typically aims at an aesthetic quality which is not available to lowend consumer grade cameras due to the lens design. We present a bokeh simulation method using stereo-vision techniques. We refine a depth map obtained with stereo matching with a little user interaction. A depthaware bokeh effect is then applied with user-adjustable apertures sizes or shapes. Our method mainly aims at the visual quality of the bokeh effect rather than time efficiency. Experiments show that our results are natural-looking, and can be similar to the bokeh effect of a real-world bokeh-capable camera system.
