These two videos introduce the observer motion problem and an approach to solving this problem. The first video provides background on how the movement of the observer, characterized by six parameters of translation and rotation around the x, y, and z axes, combined with the depth of surfaces viewed at each location in the image, gives rise to the image velocity field. The second video presents an approach to solving the observer motion problem based on the analysis of velocity changes in the image.
