The Grupo de Tratamiento de Imágenes (GTI) [Image Processing Group] is a research group working on theory, methods, and applications of Digital Image and Video Processing, mainly for compression and analysis. Besides specific developments on video related topics, GTI also considers research on complete systems like visual communications, real time computer vision, and multimedia telecom applications. Thus, GTI has developed facilities and toolkits for the design and implementation of video delivery systems and machine-learning based computer vision applications. Currently, GTI activity focuses on immersive video communications and extended (VR, MR, AR) and shared reality applications, including deep-learning for visual computing. GTI infrastructure includes three labs: a complete 3DTV laboratory (3DTV Lab) endowed with a 3D acquisition system, a 3D post-production system, and several 3D displays, a real-time free-viewpoint video laboratory (FVV Live) endowed with linear and planar camera configurations, lightweight schemes for video acquisition, transmission, and rendering, and minimal motion to photon latency, and an immersive laboratory (ImLab) for 360VR, volumetric video and extended/shared reality.
