|
integrate_area(self,
coords)
Sums up a region of interest if len(coords) == 4 -> convert coords
to slices if len(coords) == 2 -> use as slices floor -> ?
removed as unused in the function. |
source code

|
|
make_slice(self,
coords)
Convert a len(4) set of coords into a len(2) tuple (pair) of slice
objects the latter are immutable, meaning the roi can be cached |
