Synthetic images of corals (Desmophyllum pertusum) with object detection models

https://doi.org/10.5878/hp35-4809
Two object detection models using Darknet/YOLOv4 were trained on images of the coral Desmophyllum pertusum from the Kosterhavet National Park. In one of the models, the training image data was amplified using StyleGAN2 generative modeling. The dataset contains 2266 synthetic images with labels and 409 original images of corals used for training the ML model. Included is also the YOLOv4 models and the StyleGAN2 network. The still images were extracted from raw video data collected using a remotely operated underwater vehicle. 409 JPEG images from the raw video data are provided in 720x576 resolution. In certain images, coordinates visible in the OSD have been cropped. The synthetic images are PNG files in 512x512 resolution. The StyleGAN2 network is included as a serialized pickle file (*.pkl). The object detection models are provided in the .weights format used by the Darknet/YOLOv4 package. Two files are included (trained on original images only, trained on original + synthetic images). The machine learning software packages used is currently (2022) available on Github: StyleGAN2: https://github.com/NVlabs/stylegan2Opens in a new tab YOLOv4: https://github.com/AlexeyAB/darknetOpens in a new tab
