Training dataset for object detection - Penguins from UAV

On February 8, 2021, Deception Island Chinstrap penguin colonies were photographed during the PiMetAn Project XXXIV Spanish Antarctic campaign using unmanned aerial vehicles (UAV) at a height of 30m. From the obtained imagery, a training dataset for penguin detection from aerial perspective was generated. The penguin species is the Chinstrap penguin (Pygoscelis antarcticus).The dataset consists of three folders: "train", containing 531 images, intended for model training; "valid", containing 50 images, intended for model validation; and "test", containing 25 images, intended for model testing. In each of the three folders, an additional .csv file is located, containing labels (x,y positions and class names for every penguin in the images), annotated in Tensorflow Object Detection format.There is only one annotation class: Penguin.All 606 images are 224x224 px in size, and 96 dpi. The following augmentation was applied to create 3 versions of each source image:* Random shear of between -18° to +18° horizontally and -11° to +11° verticallyThis dataset was annotated and exported via www.roboflow.comThe model Faster R-CNN64 with ResNet-101 backbone was used to perform object detection tasks. Training and evaluation tasks were performed using the TensorFlow 2.0 machine learning platform by Google.
