Self-Calibration of a Camera from Video of a Walking Human
Analysis of human activity from a video camera is simplified by the knowledge of the camera’s intrinsic and extrinsic parameters. We describe a technique to estimate such param...

Intrinsic Camera Calibration Based on Radical Center Estimation
Camera calibration is an important step in obtaining 3D information from 2D images. Generally camera parameters can be obtained by using traditional methods if a calibration object...
