rotation_optimize: Rotation error measurement for two similar retinal maps.

In yinscapital/retina-analysis-reference: Tools for plotting and analyzing vertebrate retinas.

Description

Rotates one map 360 degrees, and for every value of rotation between -180 to 180, the mean absolute difference between the maps' rho values is recorded

Usage

rotation_optimize(map1, map2, spatial_res = 32, theta_interval = 30,
  projection_type = "azequidistant", ...)

Arguments

map1	retinal data: This map will not be rotated, and will serve as the reference.
map2	retinal data: This map will be rotated and superimposed upon map1. Has components $x, $y and $z in azimuthal projection coordinates.
spatial_res	Defines the number of pixels across the interpolation grid for every comparison. Default is 16 for speed.
theta_interval	Defines the interval at which the rotation value will be changed when moving to the next comparison. Default is 10 in units of degrees.
...	further arguments passed to or from other methods. reference map. latitude in [,1], longitude in [,2], rho in [,3].

Value

df_spin Matrix of errors (in second column) for a given map rotation.
