Normalize
Normalize enhances low-contrast information. At each pixel, it looks at the statistics of the rectangular neighborhood around that pixel, and stretches the pixel's value linearly to maximize visibility. By default, the output is 8-bit unsigned integers.
Arguments
| Argument | What it does | Default |
|---|---|---|
| neighborhood | Required. The width and height of the region where the statistics are measured. With one number, the region is a square | |
| sigma | Adjusts the contrast of the enhancement. Lower numbers give higher contrast. Must not be less than 0 | 3.0 |
| output type | integer, 8-bit or 16-bit; or floating, 32-bit or 64-bit | integer, 8-bit (floating: 32-bit) |
