Inputs (5)
| Name | Type | Default | Description |
|---|---|---|---|
| image | IMAGE | Input image. A batch is processed frame by frame. | |
| method | COMBO | CLAHE (adaptive) | CLAHE equalizes contrast locally and limits noise amplification (recommended); histogram equalization stretches contrast globally (simpler, can blow out). |
| channels | COMBO | luminance only (LAB) | Luminance-only keeps colors natural; per-channel can shift colors but is more dramatic. |
| clip_limit | FLOAT | 2.00.1–40 | CLAHE only: contrast limiting; higher = stronger. |
| tile_size | INT | 81–64 | CLAHE only: grid size of local regions. |
