Pre-Processing > Histogram Equalization
Equalizes image brightness and contrast across the image by performing different histogram scaling in each tile of grid of tiles whose size is defined by user .
Controls desired histogram shape for the image tiles
- Uniform: Flat-histogram
- Rayleigh: Bell-shaped histogram
- Exponential: Curved histogram
Number of tiles to split the image into in each direction (Recommended: 8)
Adjusts amount of contrast enhancement. Higher values result in more contrast (Recommended: 0.01)
