Contribution
It presents a novel pipeline leveraging pre-trained detectors and minimal labeled data to adapt species classification models to new regions.
Findings
High classification accuracy achieved in new regions
Reduced need for extensive labeled datasets
Effective transferability across geographic areas
Abstract
Biologists all over the world use camera traps to monitor biodiversity and wildlife population density. The computer vision community has been making strides towards automating the species classification challenge in camera traps, but it has proven difficult to to apply models trained in one region to images collected in different geographic areas. In some cases, accuracy falls off catastrophically in new region, due to both changes in background and the presence of previously-unseen species. We propose a pipeline that takes advantage of a pre-trained general animal detector and a smaller set of labeled images to train a classification model that can efficiently achieve accurate results in a new region.
