Description

he_pos_wgt

Blending weight curve of the histogram equalization and source image. You can increase the luminance based on the luminance of the source image. The curve is in Gaussian distribution, and the horizontal coordinates indicate luminance.

he_neg_wgt

Blending weight curve of the histogram equalization and source image. You can decrease the luminance based on the luminance of the source image. The curve is in Gaussian distribution, and the horizontal coordinates indicate luminance.
