A paper on “How to process billions of photons a second” for ultrafast and accurate 3D imaging by Dr Julián Tachella, Dr Michael Sheehan and Professor Mike Davies has won Best Student Paper award at ICASSP 2022, the top international signal processing conference.

 Figure shows 3D imaging performance of a Lidar camera in a setting with strong background illumination. Top left: an image processed “pixelwise” – or pixel by pixel – results in a “noisy” image, with less definition and accuracy. Image quality can be substantially improved with spatial regularization algorithms such as RT3D (top right). However, in both cases the data transfer involved is prohibitive. Bottom row: the pixelwise sketched Lidar reconstruction (left), and the sketched RT3D images (right). In b
