Based on animal head positions in a rectangular tunnel i.e. box,
calc_sf_box()
calculates how the animal perceives the spatial
frequency of lateral visual stimuli as modulated by distance to the stimulus.
calc_sf_box(obj_name)
obj_name | The input viewr object; a tibble or data.frame with attribute
|
---|
A tibble or data.frame with added variables min_dist_pos
and
min_dist_neg
describing the minimum distance to the tunnel walls as
well as s_freq_pos
and s_freq_neg
reported in cycles per 1deg
of visual angle.
calc_sf_box
assumes fixed gaze at the point on the
either side of the tunnel that minimizes the distance to visual stimuli and
thereby minimizes spatial frequencies.
