After the array is sliced, it becomes clear that converting converting RGB to grayscale is not a similar process. lum_img = img[:,:,0] It's surprising that there isn't a built-in function in numpy or matplotlib forConverting RGB to grayscale. After all, isn't this a frequently used...

This tutorial explains how we can convert a NumPy array to a PIL image using the Image.fromarray() from the PIL package.

1. Looks like you forgot to load the image. This method needs the RGB image array, not the path. img_as_float (image, force_copy=False) Parameters image : ndarray, shape (M, N [, 3]) - Input image, 2D grayscale or RGB. try to load the image first: original ...
