IBM-MAX Image Colorizer
Image Colorizer Example Flow
This flow uses the Image Colorizer deep learning model from the IBM Model Asset Exchange to colorize black & white images.
We are posting the original image using multipart form data. The headers, payload and url for the request can be constructed using a change or a function node respectively.
