API Documentation
Request Endpoint
Request Parameters
| Parameter Name | Type | Required | Description |
|---|---|---|---|
| imageFile | file (Upload required) | Yes | Upload any image file (JPEG, PNG, WebP, GIF, BMP, TIFF) to apply CLAHE histogram equalization |
| tileSize | range | No | Size of tiles for local histogram equalization. Smaller tiles provide more local contrast enhancement |
| contrastLimit | range | No | Contrast amplification limit. Higher values allow stronger contrast enhancement but may amplify noise |
| brightnessLimit | range | No | Brightness amplification limit. Lower values prevent over-amplification of bright areas |
| gridSize | range | No | Number of grid divisions. Higher values create more tiles for finer local enhancement |
| format | select | No | Choose output format or keep original. PNG recommended for maximum quality |
| quality | number | No | Output quality for lossy formats (JPEG, WebP). Higher = better quality but larger file size |
File type parameters need to be uploaded first via POST /upload/image-clahe to get filePath, then pass filePath to the corresponding file field.
