Abstract :
We present two linear algorithms for recovering the camera motion and 3D scene structure directly from the image data in a a multi-image sequence. The first algorithm generalizes the point-based approach of Oliensis (1999) to intensities. The second generalizes the Lucas-Kanade (1981) optical-flow method to a direct method
