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.

A background subtraction algorithm for a pan-tilt camera
2014 IEEE International Conference on Robotics and Biomimetics (ROBIO 2014), 2014This paper is concerned with the detection of moving objects using a pan-tilt camera and a background subtraction algorithm. Traditionally, motion compensation is performed on the current image to align its pixels with their background models in previous frames. Pixel misalignment however can occur during motion compensation.

Improvement in detection of abandoned object by pan-tilt camera
2016 8th International Conference on Knowledge and Smart Technology (KST), 2016Recently, security cameras have been installed at a high rate in places where there are extensive grounds and many humans gather. The number of installed security cameras has been increasing year by year. The main reason is security enhancement including the prevention of incidences of terrorism.

Image-based pan-tilt camera control in a multi-camera surveillance environment
2003 International Conference on Multimedia and Expo. ICME '03. Proceedings (Cat. No.03TH8698), 2003In automated surveillance systems with multiple cameras, the system must be able to position the cameras accurately. Each camera must be able to pan-tilt such that an object detected in the scene is in a vantage position in the camera's image plane and subsequently capture images of that object. Typically, camera calibration is required.

A motion controller for a pan-tilt camera on an autonomous helicopter
2010 11th International Conference on Control Automation Robotics & Vision, 2010In this paper, a motion controller for a pan-tilt camera mounted on an autonomous helicopter is presented. The motion planner is designed according to the kinematics of the pan-tilt camera. However, the solution of the inverse kinematics of the pan-tilt camera is not unique. To deal with this situation, a decision maker is designed.

A Simultaneous Multi-Object Zooming System Using an Ultrafast Pan-Tilt Camera
IEEE Sensors Journal, 2021This paper presents a novel dual-camera system that can simultaneously capture zoomed-in images using an ultrafast pan-tilt camera and a fixed wide-view camera using deep learning methods. An ultrafast pan-tilt camera can function as multiple virtual pan-
