Some suggestions:
- the input image should be 1024x512. If I’m not mistaken - the AI is trained with 512x512 images so if its multiples of that size you’re good
- the problem here is you just see a fragment of the pool. The AI isn’t smart enough to know its a pool if the whole shape isn’t visible. In that case I use Segment colors. See one of my previous post of 19 days ago.
If I apply a few segment colors, the pool gets picked up nicely. See pics.
