Pysaliency is a python package for saliency modelling. It aims at providing a unified interface to both the traditional saliency maps used in saliency modeling as well as probabilistic saliency models. Pysaliency has a range of influential models prepackaged and ready for use, as well as some public available datasets. These models are using the original code which is often matlab. Therefore, a matlab licence is required to make use of these models, although quite some of them work with octave, too (see below).

Make sure all packages from requirements.txt are installed. Then as usual, the package is installed by

python setup.py install

If you want to use the SALICON dataset you have to install the salicon python api.

import pysaliency

dataset_location = 'datasets'
model_location = 'models'

mit_stimuli, mit_fixations = pysaliency.external_datasets.get_mit1003(location=dataset_location)
aim = pysaliency.AIM(location=model_locations)
saliency_map = aim.saliency_map(mit_stimuli.stimuli[0])

plt.imshow(saliency_map)


auc = aim.AUC(mit_stimuli, mit_fixations)

If you already have saliency maps for some dataset, you can import them into pysaliency easily:

my_model = pysaliency.SaliencyMapModelFromDirectory(mit_stimuli, '/path/to/my/saliency_maps')
auc = my_model.AUC(mit_stimuli, mit_fixations)

pysaliency will fall back to octave if no matlab is installed. Some models might work with octave, e.g. AIM and GBVSIttiKoch. In Debian/Ubuntu you need to install octave, octave-image, octave-statistics, liboctave-dev.

These models and dataset seem to work with octave:

• models
  • AIM
  • GBVSIttiKoch
• datasets
  • Toronto
  • MIT1003
  • MIT300
  • SALICON
