Tree detection is off. Parameter problem? Spatial resolution problem? #61

Hey, it's the first time for me to use this deep learning toolbox.

It seems that there's a problem with the detection.

I guess it can detect the trees but the bounding boxes are very small.

What am I doing wrong? I'm using the default parameters and my TIF file looks OK.

The GSD is 5cm/pixel.

From the model spec: https://www.arcgis.com/home/item.html?id=4af356858b1044908d9204f8b79ced99,

It's specified that the model works well for 8 bit, 3-band high-resolution (10-25 cm) imagery. Basically, 2x to 5x less precise than my imagery.

Could it be the problem?

Thanks

So it seems like it is due to a higher than expected resolution. I downsampled the TIF file and I can get better results.
