Global Equalization |
Global histogram equalization adjusts the gray value distribution of an image to make it more uniform, enhancing the contrast of the image. Contrast Limited Adaptive Histogram Equalization (CLAHE) is used to improve the local contrast of the image. |
Contrast limit threshold |
Float |
[0, 100] |
2 |
Contrast limit threshold. |
Grayscale coefficient |
Integer |
[1, 30] |
8 |
Grayscale coefficient, offset of image correction, used to adjust brightness, the brighter the image, the darker the smaller the image. |
