Runs the FMask cloud and shadow matching. Outputs a single band ('csm'), containing the computed cloud and shadow masks.
| Usage | Returns | ee.Algorithms.FMask.matchClouds(input, cloud, shadow, btemp, sceneLow, sceneHigh, neighborhood) | Image |
| Argument | Type | Details | input | Image | The scene for which to compute cloud and shadow masks. |
cloud | Image | Potential cloud mask image. Expected to contain 1s for cloudy pixels and masked pixels everywhere else. |
shadow | Image | Potential shadow mask image. Expected to contain 1s for shadow pixels and masked pixels everywhere else. |
btemp | Image | Brightness temperature image, in Celsius. |
sceneLow | Float | The 0.175 percentile brightness temperature of the scene. |
sceneHigh | Float | The 0.825 percentile brightness temperature of the scene. |
neighborhood | Integer, default: 50 | The neighborhood to pad around each tile. |
