1. Long-term photographic recordings of animal populations provide unique insights into ecological and evolutionary processes. However, image acquisition at remote locations under harsh climatic conditions is highly challenging. 2. We present a robust, energetically self-sufficient and remote-contro... 

Scientific applications often require an exact reconstruction of object positions and distances from digital images. Therefore, the images need to be corrected for perspective distortions. We present CameraTransform, a python package that performs a perspective image correction whereby the height, t... 

Emperor penguins (Aptenodytes forsteri) breed during the harsh Antarctic winter. During mating and breeding period (in total up to four months), the males must fast, while also incubating the egg during the latter. To survive and breed successfully, they must conserve their energy. Through evolution... 

Automated image based tracking is widely used to investigate collective interactions in a variety of biological systems. Applied to diverse environments, ranging from cell to animal colonies, it provides insight into biological processes like cancer metastasis, immunological response, and social str...
