Project 2: pb-lite — Sam Birch (sbirch)

CS143 10/12

This is an implementation of pb-lite. It beats the canny baseline, barely! Perceptually, it seems to reduce edge strengths corresponding to texture gradients, as it is designed to do. I didn't make any interesting decisions implementing the project.

And statistics:

Boundary
ODS: F( 0.66, 0.54 ) = 0.59   [th = 0.12]
OIS: F( 0.62, 0.57 ) = 0.60
Area_PR = 0.52
