The sanity check prevents Python 2 from calling findContours, because the Python 2 bindings pass an empty matrix for `_contours`. If `_contours` is not empty, the channel and depth check should determine whether the matrix is of the correct type and size. Note: the Python 2 bindings passes a matrix of type `STD_VECTOR_MAT` to parameters of the type `OutputArrayOfArrays`. |
