How to display an image in a Jupyter Notebook with Julia?

Question

I have some image data like the following:

224×224×3×2 Array{Float32, 4}:
[:, :, 1, 1] =
 0.117647   0.117647   0.117647   0.117647   …  0.384314  0.396078  0.403922
 0.117647   0.117647   0.117647   0.117647      0.384314  0.392157  0.4
 0.117647   0.117647   0.117647   0.117647      0.384314  0.388235  0.392157
 0.121569   0.117647   0.121569   0.121569      0.388235  0.388235  0.388235
 0.12549    0.117647   0.12549    0.129412      0.396078  0.396078  0.396078

which I was using for some ML models. I want to be able to visualize the images in a notebook.

Right now I can do ImageView.imshow but that opens the image outside of the notebook. How can I display the image inside of the notebook?

Answer 1

Just do:

IJulia.display(image)

For an example:

using Images
image = [RGB(rand(N0f8,3)...) for x in 1:200, y in 1:150]
using IJulia
IJulia.display(image)
