Jointly with @KarakusOktay, we introduced a robust Kalman filtering method, the RKFNet, which combines a heavy-tailed-based RKF with deep learning and hence eliminates the need for precise parameter estimation of heavy-tailed distributions encountered in tracking applications.

Very proud of our ex-PhD student, Xin Tian, who soon after joining Oxford University as a postdoctoral researcher, got another part of her PhD thesis accepted as Research Article in Biological Imaging. - bit.ly/49IxWtl @VILaboratory @bristolcs @BristolUniEng

We also introduced a unique dataset comprising mouse OCT and confocal retinal images, facilitating the development of- and establishing a benchmark for- cross-modal image translation research doi.org/10.5523/bris.1hvd8aw…

This marks the first attempt to exploit the inherent 3D information of OCT and translate it into the rich, detailed color domain of confocal microscopy.
