Shen-Chuan Tai, Shih-Ming Yang, 'A fast method for image noise estimation using Laplacian operator and
adaptive edge detection', Communications, Control and Signal Processing, 2008. ISCCSP 2008
Correct equation in :
O. Laligant, F. Truchetet, E. Fauvet, 'Noise estimation from digital
step-model signal', IEEE Trans. Image Processing, 2013 Dec., 22(12):5158:67
Parameters:
sigma = TaiYang(Im, p, comment)
Im : image
p : percentage of points having low gradient to take into account comment
returned result : noise standard deviation (sigma)
Example : [sigmaTai, useful_pixels_percentage] = TaiYang("house.bmp", 10, 0);
