Larch Casebearer detection Computer Vision Project

The larch casebearer, Coleophora laricella, is a moth that mainly attacks larch trees and has caused significant damage in larch stands in Västergötland, Sweden.

Original dataset of aerial drone images of larch forests was modified to remove duplicates or badly annotated images. Only images taken in may (20190527) are present here as they contain damage level classes. Also, the annotation files in Pascal VOC XML format were converted to YOLO PyTorch TXT format.

Images were taken in 5 areas around Västergötland, Sweden and the names of the files correspond to different areas:

• B01 - Bebehojd
• B02 - Ekbacka
• B03 - Jallasvag
• B04 - Kampe
• B05 - Nordkap

There are 4 classes in total:

• H - healthy larch trees
• LD - light damage to larch trees
• HD - high damage to larch trees
• other - non-larch trees

Training, validation and testing images were selected from different acquisition sites to try creating a better generalizing detection model.
