A Plot of the Light Intensity of a Lambertian Sphere
(uniform albedo, point light source & oberver are at infinite distance)
Light source pans from -90 degrees to +90 degrees and back)

 

Contour Plot of the Intensity
(not synchronized with the above)


 
 

Histogram of the Intensity of Pixels of Lambertian Sphere Range Image

vs the Lambertian Sphere Optical Image

X-Axis is Range, Y-Axis is Optical
Corresponds loosely to First Eigenvector

 

Histogram of the Derivitive of Intensity of Pixels of Lambertian Sphere Range Image

vs the Lambertian Sphere Optical Image

X-Axis is Range, Y-Axis is Optical
Corresponds loosely to Second and Third Eigenvectors
