WebMethod 2: Using the opencv package. The other method to convert the image to a NumPy array is the use of the OpenCV library. Here you will use the cv2.imread () function to read the input image and after that convert the image to NumPy array using the same numpy.array () function. Execute the below lines of code to achieve the conversion. Webnumpy.invert(x, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) = #. Compute bit-wise inversion, or bit-wise NOT, element-wise. Computes the bit-wise NOT of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python ...
