Nonuniform Illumination Correction¶
Corrects for nonuniform lighting in an image.
returns Grayscale image after correction
- img - RGB or grayscale image
- ksize - Kernel size
- Corrects for nonuniform illumination for situations where there is no available background image to do background subtraction. The function corrects for nonuniform lighting by creating a background image from the original by blurring with the specified kernel size.
