CV HDR Exposure Fusion (Mertens)
Blends a batch of exposures straight into one display-ready image, keeping each region from whichever frame exposed it best (well-exposedness x contrast x saturation). Needs no exposure times and no separate tonemapping - the simplest, most robust HDR-look path. Output is an ordinary 0..1 IMAGE.

| Name | Type | Default | Description |
|---|---|---|---|
| image | IMAGE | Batch of registered exposures of the same scene (tripod, or pre-aligned). | |
| contrast_weight | FLOAT | 1.00–5 | Emphasis on locally contrasty (in-focus, textured) pixels. 0 ignores contrast. |
| saturation_weight | FLOAT | 1.00–5 | Emphasis on saturated (vivid) pixels. |
| exposure_weight | FLOAT | 1.00–5 | Emphasis on well-exposed (mid-tone) pixels - the heart of the fusion; low values let blown highlights and crushed shadows leak in. |
