Distant thin objects (e.g., street lamps) vanishing due to sky mask interpolation

[Shilin-Zhao]

Hi, I noticed that thin objects like street lamps often flicker or disappear in the results.

This seems to be caused by the default interpolation when resizing sky masks. It introduces intermediate values (not 0 or 1) at the edges, which messes up the sky_mask == 0 check.

Switching to Nearest Neighbor interpolation fixes this issue and makes thin objects stable.

Hi. Thank you for your valuable suggestion.
We will try to put it into practice and make appropriate adjustments accordingly.

Hi, following up on this.

I have submitted a PR ( #31) that implements this fix. It switches the sky mask resizing to Nearest Neighbor interpolation.

In my experiments, this simple change effectively preserves thin structures (like street lamps) that are correctly detected by the segmentation model but often lost due to resizing artifacts in the default implementation.

Please feel free to test it out if you are interested. Hope this helps!
