Zemin Cai, Chuliang Wei · Procedia Engineering · 2011
In recent years, there is a growing interest in the research of color image de-noising algorithms. A tight framelet is a wavelet frame constructed by multiresolution analysis. The properties of tight framelet and its applications on gray image denoising have been well studied. Our goal is to explore the power of tight framelet to de-noise color images. We analyze the relationship between gray images and color images. The frame-based gray image de-nosing scheme is extended to color image de-noising. Experimental results of color image de-noising show that the new method has a better performance than AMF approach.
