Coded Aperture solution using de-convolution

Computer Vision

 

Project Description:
 

Patterned mask inserted at the aperture stop of a camera preserves high frequency components and increases the sensitivity of details sharpness to defocus. This can be used to derive depth map through an estimated blurring function as well as to control the focal plane, in order to be able to focus on different objects in an image.

This project will be done in cooperation with Intel.

Project Goal:
 

Use simulations for feasibility study of Z data extraction and refocus control, based on coded aperture principle.
In the first step we will use simulations (Fourier based) to create the patterned mask effect on still images. Then we will use a promising de-convolution scheme to recover Z information, given full calibration data for the defocus blurring function.
