It may seem tedious to train AI detectors for the first time. However, there is a way to significantly reduce training time while increasing accuracy.
In case of Images. You can select only several images for the detection:
- Hover mouse over image tile, a checkbox will appear
- Select as many images as you wish
Now when you’ll train or run a detector, you’ll have an option to run detection only on the selected images.
In case of Maps. On the orthomosaic one can define working areas. Working area is a region on the map. To draw a working area:
- Select either rectangular or polygonal drawing tool from toolbar (see 1 on the picture below)
- Draw on the map
- Working areas appear on the map as white dashed figures. They also appear in the list in the right panel (see 2 on the image below)
Later when you’ll train or run a detector, you’ll have an option to run detection only on the selected working areas.
Selecting images and working areas may not only significantly reduce processing time but increase accuracy as well. In many cases, objects can be localized in certain areas. Thus selecting working areas may reduce the number of false positives in the area where objects can not be.
You’ve learned a very important concept. Congratulations!
