Abstract

Multi focused image fusion combines two or more images focusing different objects in the same scene to produce all-in-one focus image without artifacts and noises. Among two scale edge preserving filters used in multi focused image fusion, Bilateral Filters plays a vital role since it preserves edge information and avoids staircase effect. This paper analyses the performance of Standard Bilateral Filter (SBF) and its variant Robust Bilateral Filter (RBF) and Weighted Bilateral Filters (WBF) in fusing multi focused images in terms of Quality Index and Mutual Information.
