Why do I use CRF code to come out like this?

Hello, Thanks for sharing the code. But I have a question, why do I use the CRF code to come out like this?

PS: My train image data is three channel image. And my prediction image is already colored three-channel image data. I used the CRF function to pass in the original image, the colored image and the output image, I don't know if it's a mistake?
