Description

wgt

Maximum value of Gaussian distribution in the weight curve of blending local histogram equalization results and source image based on the luminance increment.

The value range is [0x0, 0xFF].

sigma

MSE value of Gaussian distribution in the weight curve of blending local histogram equalization results and source image based on the luminance increment.

Value range: [0x1, 0xFF]

mean

Expected value of Gaussian distribution in the weight curve of blending local histogram equalization results and source image based on the luma increment.

The value range is [0x0, 0xFF].
