Optical flow camera calibration
WebOn the whole, the optical flow stitching algorithm is better, but not all scenes and all films have better optical flow stitching, which depends on the effect of the actual scene. The "Chromatic Calibration" function is mainly used when the video has color difference or light and dark color difference. WebFirst Principles of Computer Vision This lecture series on computer vision is presented by Shree Nayar, T. C. Chang Professor of Computer Science at Columbia Engineering. It has been designed for students, practitioners and enthusiasts who have no prior knowledge of computer vision.
