Focus Measure of Light Field image using ModifiedLaplacian and Weighted Harmonic Variance

Abstract

A light field image generates a set of focusing images at different depth levels. When we reconstruct an allfocused image, we have to identify in-focused regions of the stack images. To address this problem, we propose a method to detect in-focused image regions. We employ sum-modified-laplacian and weight harmonic variance algorithms to solve the problem… (More)
