derotation.analysis.mean_images#

This module contains functions to calculate mean images in steps of 10 degrees. It is used when finding the center of rotation.

Functions

calculate_mean_images(image_stack, rot_deg_frame)

Calculate the mean images for each rotation angle.
derotation.analysis.mean_images.calculate_mean_images(image_stack, rot_deg_frame, round_decimals=2)[source]#

Calculate the mean images for each rotation angle. This required to calculate the shifts using phase cross correlation.

Parameters:

  • rotated_image_stack (np.ndarray) – The rotated image stack.

  • rot_deg_frame (np.ndarray) – The rotation angles for each frame.

  • round_decimals (int, optional) – The number of decimals to round the angles to, by default 2

Returns:

The mean images for each rotation angle.

Return type:

np.ndarray
