- lentil.helper.boundary_slice(x, threshold=0, pad=(0, 0))¶
Find bounding row and column indices of data within an array and return the results as slice objects.
x (array_like) – Input array
threshold (float, optional) – Masking threshold to apply before boundary finding. Only values in x that are larger than threshold are considered in the boundary finding operation. Default is 0.
pad (int or tuple of ints) – Additional number of pixels to pad the boundary finding result by. Default is (0,0).
row_slice, col_slice – Boundary slices
- Return type
tuple of slices
