In signal processing we are engaged in theory and applications of signals from sensor arrays. Medical ultrasound, sonar, atmospheric Infrasound, and acoustic localization are examples of our research domains in this direction.

In image analysis we focus on automatic methods for extracting information from images. Medical imaging and remote sensing are examples of important application areas.

Deep learning remains an important direction and several of our projects are in the forefront of machine learning research, development, and application. The group is responsible for one of the most popular MSc courses in the department: IN4310/IN3310 – Deep learning for image analysis.
Most of our research topics can be classified as imaging, i.e. making images of hidden structures (in the body, in the ground, in the sea). 

The DSB group cooperates with a cluster of Norwegian companies in acoustics, sonar and ultrasound technology. Some of the companies are startups initiated by our  employees and former students.
