Seminar 03/12 – Steve McLaughlin – Computational Imaging in Disordered Media

For the next STORM seminar, Steve McLaughlin will give a presentation titled : Computational Imaging in Disordered Media

Abstract

Single-photon lidar has emerged as a prime candidate technology for depth imaging through challenging environments. Until now, a major limitation has been the significant amount of time required for the analysis of the recorded data. Here we show a new computational framework for real-time three-dimensional (3D) scene reconstruction from single-photon data. By combining statistical models with highly scalable computational tools from the computer graphics community, we demonstrate 3D reconstruction of complex outdoor scenes with processing times of the order of 20 ms, where the lidar data was acquired in broad daylight from distances up to 320 metres. The proposed method can handle an unknown number of surfaces in each pixel, allowing for target detection and imaging through cluttered scenes. This enables robust, real-time target reconstruction of complex moving scenes, paving the way for single-photon lidar at video rates for practical 3D imaging applications.
In the latter part of the talk I will discuss new developments in speckle imaging through multimode fibres and through disordered media.

This seminar will take place on Friday 03/12 at 12:30pm in room Salle des Thèses at IRIT.

Cheers !
