Hello! How do I make a image recognition tool to count object and measure distances in one picture? How to use that in QGIS? Thank you

Answer 1

If you really need to analyse a raster image, use OpenCV. It is an open-source computer vision system with a nice community and modules for python. If you need to analyse a layer in QGIS, try to use Ftools instead, a python plugin to QGIS.
