Create polygon from images

Hello everbody!

There is an image with edge detection operator applied.

From this image, parcel boundaries were obtained in the form of lines. (as "line.shp" file)

(the image is attached.)

In this image (or "line.shp" file), I want to get the parcel borders as a polygon and there are methods such as perceptual grouping..

Is there a package program or aplication for perceptual grouping?

or Is there another method that I can apply more easily.?

or how do I get it?

thanks in advance

What does the original look like? Because often beginners just automatically do edge detection for some reason even when that's not the correct approach. I saw one of those just this morning.

It looks like a good candidate for watershed segmentation.

Dear Matt J.

I tried the algorithm you mentioned (watershed segmentation), but I could not reach the exact result I wanted.Result image is the below

the result I want to achieve; should be as in the below sample image.
