How can DBSCAN be applied to image with sobel filter in python?

Question

I already know that To use DBSCAN on images, we need to convert the image into a set of data points. Considering this, I'm wondering if it's feasible to apply DBSCAN to an image that has undergone Sobel filtering. Specifically, I'm thinking about converting the additional lines or edges that emerge from the Sobel-filtered image. Could this be achieved? or is there other methods to accomplish this?
