Activity 17: Photometric Stereo

Photometric stereo uses light intensity from different light sources to infer the shape of a three-dimensional surface. For this activity we used four images of a sphere illuminated with four light sources positioned at different locations. For each source, the corresponding images are the following

The reconstruction is shown below

The reconstruction is imperfect as shown in figure 2. However, to some extent the 3D features of our object has been reconstructed.

For this activity, I'll give myself a 9 because my code uses lots of for loops.
