Wavelet and guided filter based multifocus fusion for noisy images

摘要

Wavelet and guided filter based fusion for multifocus images is proposed. Existing guided filter based scheme has limited performance for images having noise. Wavelet based denoising and guided filter based weight maps are proposed to overcome this limitation. Simulation results when analysed visually and quantitatively depict the significance of the suggested scheme. (C) 2015 Elsevier GmbH. All rights reserved.
