FG_RNN

Figure-Ground Organization with a Biologically Plausible Recurrent Neural Network

Demo

To run the model,

  1. Run Setup.m for instructions on how to run model.
  2. Model parameters can be adjusted in mfiles/makeDefaultParams.m
  3. A demo of the model is found in demo.m

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.

We refer the reader to the authors' original papers detailing the datasets and benchmarks:
