Predicted Histogram of the Intensity of Pixels of Range Images vs the Intensity of Pixels of Coregistered Optical Images

Based on Cross-Section of Lambertian Sphere
X-Axis is Range, Y-Axis is Optical
Corresponds loosely to First Eigenvector
Animation Corresponds to the Point Light Source Moving from 180 degrees through zero to -180 degrees, and then looping back.

Predicted Histogram of the First Derivative of Intensity in Range Images vs the First Derivative of Intensity of Coregistered Optical Images

Based on Cross-Section of Lambertian Sphere
X-Axis is Range, Y-Axis is Optical
Corresponds loosely to Second and Third Eigenvectors
Animation Corresponds to the Point Light Source Moving from 180 degrees through zero to -180 degrees, and then looping back.
