[paper] 00035 Synthetic Depth-of-Field with a Single-Camera Mobile Phone

Google Research

Paper name aimed two point:   1. Synthetic Depth-of-Field

                                                  2. Single-Camera Mobile Phone

Key Words:

Shallow depth-of-field: When the depth of field is small, or shallow, the image background and foreground are blurred, with only a small area in focus

dual-pixel:

 Dual pixel technology effectively divides every single pixel into two separate photo sites. Each pixel consists of two photodiodes that sit side by side next to each other under a micro lens.

alpha matte:

A matte is a layer (or any of its channels) that defines the transparent areas of that layer or another layer.

Bayer plane:

Background:

cell phone's carema is all-in-focus images.

AIM:

We present a system to computationally synthesize shallow depth-of-field images with a single mobile camera and a single button press.

Result:

    Our system can process a 5.4 megapixel image in 4 seconds on a mobile phone, is fully automatic, and is robust enough to be used by non-experts.
