function

skimage.transform.integral:integrate

source: /dev/scikit-image/src/skimage/transform/integral.py :52

Signature

def   integrate ( ii ,  start ,  end )

Summary

Use an integral image to integrate over a given window.

Parameters

ii : ndarray

Integral image.

start : List of tuples, each tuple of length equal to dimension of `ii`

Coordinates of top left corner of window(s). Each tuple in the list contains the starting row, col, ... index i.e [(row_win1, col_win1, ...), (row_win2, col_win2,...), ...].

end : List of tuples, each tuple of length equal to dimension of `ii`

Coordinates of bottom right corner of window(s). Each tuple in the list containing the end row, col, ... index i.e [(row_win1, col_win1, ...), (row_win2, col_win2, ...), ...].

Returns

S : scalar or ndarray

Integral (sum) over the given window(s).

Examples

arr = np.ones((5, 6), dtype=float)
✓
ii = integral_image(arr)
integrate(ii, (1, 0), (1, 2))  # sum from (1, 0) to (1, 2)
integrate(ii, [(3, 3)], [(4, 5)])  # sum from (3, 3) to (4, 5)
integrate(ii, [(1, 0), (3, 3)], [(1, 2), (4, 5)])
