Paper Abstract

This paper presents a multi image fusion approach for artificially reducing the depth of field in handheld phone camera photographs. The system captures a low resolution focal stack of images with variable focus settings, and two high resolution images: one with maximum scene blur and another one with maximum sharpness. The focal stack is used to guide the segmentation of the object of interest from the sharp image, which is then blended onto the background obtained from the blurry image, resulting in a visually pleasing image with a shallow depth of field effect.
