     sigma of Gaussian function to apply Gaussian filtering.<br />
     Assign an array of multiple sigma to apply MSR.<br />
     It is recommended by most researches to use 3 different scales (balance between speed and quality).

+- lower_thr: (Default: 0)<br />
     After applying MSR, a normalization is applied to the value range [Floor,Ceil] of the image.<br />
     This parameter define the ratio of pixel number to determine the Floor of value range. 0 means using the minimum pixel value in the image.<br />
     Valid range is [0,1), and the sum of lower_thr and upper_thr should be less than 1.
 
-- upper_thr: (Default: 0)
+- upper_thr: (Default: 0)<br />
     After applying MSR, a normalization is applied to the value range [Floor,Ceil] of the image.<br />
     This parameter define the ratio of pixel number to determine the Ceil of value range. 0 means using the maximum pixel value in the image.<br />
     Valid range is [0,1), and the sum of lower_thr and upper_thr should be less than 1.<br />
     Increase it if there are some extreme bright parts in the output image which makes the whole image too dark.
 
-- fulls: (Default: True for RGB/YCoCg input, False for YUV/Gray input)
+- fulls: (Default: True for RGB/YCoCg input, False for YUV/Gray input)<br />
     Determine the value range of input clip. True means full range/PC range, and False means limited range/TV range.
 
-- fulld: (Default: fulls)
+- fulld: (Default: fulls)<br />
     Determine the value range of output clip. True means full range/PC range, and False means limited range/TV range.<br />
     Set different value for fulls and fulld will result in range conversion.<br />
     When fulls and fulld are the same, it is safe to assign either True or False for any kinds of input clip except YUV. When fulls=False it will automatically determine the Floor and Ceil of input image, which may produce a stronger filter result under some circumstances.
