In this paper,we propose a color image denoising algorithm based on the second generation Bandelet transform to aim at the latest development of the characteristics of the Bandelet transform. The algorithm takes full advantage of the inherent geometry regularity of color images, gets the optimization expression, sets the threshold using noise intensity, and realizes color image denoising using the softthreshold function.
