Depth from Defocus (DFD) technique estimates the depth to each point on a target object by exploiting difference of blur in a set of multi-focus images. Conventional DFD techniques acquire such multi-focus images by varying the distance between the lens and the target object or between the lens and the image sensor. In this study, we explore Depth from Iris (DFI) techniques, which instead generate multi-focus images by controling the lens iris to vary the aperture of the lens. Refering to our prior works that implement DFD using a Convolutional Neural Network (CNN), we likewise realize the DFI framework on a CNN in this study, and evaluate the accuracy of the resulting depth estimation. |
