filter_cloudmask

typhon.cloudmask.filter_cloudmask(cloudmask, threshold=1, connectivity=1)

Filter a given cloudmask for small cloud objects defined by their pixel number.

Parameters

• cloudmask (ndarray) – 2d binary cloud mask (optional with NaNs).

• threshold (int) – minimum pixel number of objects remaining in cloudmask.

• connectivity (int) – Maximum number of orthogonal hops to consider a pixel/voxel as a neighbor (see skimage.measure.label()).

Returns

filtered cloudmask without NaNs.

Return type

ndarray
