Dynamic spatial reconstruction
WebThere is a need to improve dynamic PET to allow fine temporal sampling of 1-2 seconds. However, the reconstruction of these short-time frames from tomographic data is extremely challenging as the count level of each frame is very low and high noise presents in both spatial and temporal domains. WebFeb 1, 2024 · 1. Introduction. Real-time 3D reconstruction has become one of the most active research topics in the fields of robotics and computer vision. The 3D reconstruction is the process where various aspects of real visual world are reconstructed in virtual world like, geometry of the object, motion of particular object in the scene and also observed …
