Figure 5

Summary of data from Experiment 1. (Top) In Condition A, the globally concave surfaces were specified using only shading information. The disparities were set to zero. (Bottom) In Condition B, the same surfaces were specified with shading and correct disparities. Colors represent different lighting tilts on the test object. The ellipses summarize the mean and standard deviation of the settings for each condition with lighting tilt and slant represented as in Figure 4. The line segments connect the center of each ellipse (the average setting) to the true lighting direction. The numbers under each plot are the average angular error (ε) and the average standard deviation of the settings (SD).
