Converted image not displaying

[Abder-Rahman Ali]

I'm trying to convert a color image to a grayscale image, as follows:

from skimage import io
from skimage.color import rgb2gray 
img = io.imread('baboon.png')
img_grayscale = rgb2gray(img)
io.imshow(img_grayscale)

The code works fine, but the image does not get displayed, why is that?

Thanks.

Did you try addind io.show() at the end of your script?

Cheers,

Do  io.show() for the image to pop up. It's similar to the matplotlib drawing where you first draw and then show.

You can also use skimage.viewer.ImageViewer to view the image. Although, I actually don't know why simply imshow did not pop out the image in the viewer.

Thanks a lot for your replies. The code that works for me looks as follows:

import skimage.io as io

from skimage.color import rgb2gray 

img = io.imread('baboon.png')

img_grayscale = rgb2gray(img)

show_grayscale = io.imshow(img_grayscale)

io.show()
