Denoising images for image segmentation

Hi there,

I'm working on a task to preprocess a dataset used to detect different types of ground surfaces through an image segmentation model. Here is a sample:

And after applying Canny edge detection and inverting the image, I get this

The problem is, for ground surfaces where there is a lot of vegetation, grass and stuff, Canny gives me a very noisy surface which I can't preprocess. …
