Stimuli from Domijan (2015)

This module reproduces all of the stimuli used by Domijan (2015) as they were provided to the model described in that paper. Since the stimulus sizes were only defined in pixel-space, there is some ambiguity with respect to the stimulus sizes in degrees visual angle. To help solve this ambiguity, we approximated a realistic resolution of the stimuli (ppd = 10) which is set as default value. However, because of the ambiguity, it is possible to change the stimulus sizes by providing at least two of the following: a shape (in pixels), a visual_size (in degrees) and/or a resolution (in ppd).

Each stimulus is provided by a separate function, which can be listed using

>>> import stimupy.papers.domijan2015
>>> help(stimupy.papers.domijan2015)

The output of each of these functions is a stimulus dictionary.

For a visual representation of all the stimuli and their mask, simply run this module from the shell

$ python -m stimuli.papers.domijan2015

or from within python:

>>> from stimupy.utils import plot_stimuli
>>> from stimupy.papers import domijan2015
>>> plot_stimuli(domijan2015.gen_all())
