Model Results and Evaluation

Model results can be found in the output directory. The results are separated by type:

• edge (contour detection)
• ori (figure-ground assignment)
• group (segmentation)

Evaluation code for the contour detection task can be found here.

Evaluation code for the figure-ground assignment task can be found here.
