If you prefer working with floating point images, img_as_float () can be used to convert the image: >>> >>> from skimage.util import img_as_float >>> image = img_as_float(any_opencv_image) Using an image from skimage with OpenCV

The problem with your code might be that np.nan is a float64 type value but the np.r_ [] expects comma separated integers within its square brackets. Hence you need to convert them to integer type first. But we have another problem here. return np.r_ [ [ (int) (np.nan)] * head, x, [ (int) (np.nan)] * tail] This should have solved the problem ...
