D) it is impossible to affect edge rate without affecting global optical flow.

Question

Quizplus · Accepted Answer

Systematic changes in texture density can affect the perception of edge rate as they alter the spatial frequency and contrast in an image, influencing how edges are detected and processed. However, this does not necessarily affect global optical flow, which is concerned with the motion of objects and the observer relative to the environment. Global optical flow is more about the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer and the scene, not just the texture or edge density.
