Model Card for butterfly_detection_yolo

This model takes in images of butterflies as photographed for museum collections and detects butterfly components (L/R forewings, L/R hindwings and body) as well as color checkers and metadata labels. The detection model described here is used in the repository https://github.com/Imageomics/wing-segmentation to detect components and use Meta's Segment-Anything (SAM) model for segmentation of components.

Model Details

yolo_detection_8m_shear_10.0_scale_0.5_translate_0.1_fliplr_0.0_best.pt is the butterfly detection model.

The yolo v8 detection model was trained on a dataset of 800 total images from the Heliconius Collection-Cambridge Butterfly, OM_STRI, and Monteiro datasets. The model uses the pretrained yolov8m.pt model.

Model Description

The model is responsible for taking an input image (RGB) and generating bounding boxes for all classes below that are found in the image. Data augmentations applied during training include shear (10.0), scale (0.5), and translate (0.1). The model was trained for 50 epochs with an image size of 256. Note that despite defining an image size of 256, the normalized masks predicted by yolo can be rescaled to the original image size.
