Title: Unsupervised Domain Adaptation of Underwater Images

Abstract:

Thousands of high quality images of the underwater environment are being captured through the ACFR’s marine robotics program.  Machine learning tasks such as classification and object identification can be used to automate image analysis but these models rely on ground truth annotations from experts for training.  Only a small percentage of images have been annotated which results in machine learning models that do not transfer well to images taken from different robotic platforms, regions or water and lighting conditions.  This seminar will present how unsupervised domain adaptation can be used to adapt machine learning models that have been trained on one source domain to a new target domain to reduce the need to annotate images from the target domain.  Two approaches will be reviewed that adapt the domain at a representation layer and at an image level.  Intermediate results  will be discussed and how future research will enhance these techniques for domain shifts between different sets of underwater images.
