Cone beam SPECT reconstruction with camera tilt
Physics in Medicine and Biology, 1989The authors modified the cone beam filtered backprojection algorithm of L.A. Feldkamp et al. (1984) and applied it to the symmetric tilt-angle case. Both the modifications of the algorithm and a single preliminary test are reported.

Keeping a Pan-Tilt-Zoom Camera Calibrated
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2013Pan-tilt-zoom (PTZ) cameras are pervasive in modern surveillance systems. However, we demonstrate that the (pan, tilt) coordinates reported by PTZ cameras become inaccurate after many hours of operation, endangering tracking and 3D localization algorithms that rely on the accuracy of such values. To solve this problem, we propose a complete model for a

Background modelling for pan tilt camera
2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014Background modeling is commonly used in image processing applications. Stationary camera assumption, the basic assumption of background modeling, becomes invalid in some cases such as movement of camera, movement of platform on which the camera is mounted, oscillation of camera due to wind etc.
