Virtual out of focus with single image to enhance 3D perception

Abstract

The color, contrast and detail of an object in focus are accentuated, whereas those of a background are attenuated based on the estimated depth map with a face detection and segmentation method for enhancing a 3D perception. Considering the human perception and a real out of focused image taken with wide aperture lens, we suggest a boundary gradation for the estimated depth map to handle blurring errors. To make a blurred background, we perform a modified Gaussian pyramid by scaling up and blending all of images.
