Project description

FastDDM

Python

FastDDM is a Python package for the analysis of microscopy image sequences using Differential Dynamic Microscopy on CPU and GPU. The features implemented are targeted at the experimental soft matter research community dealing with inert and active/biological samples.

Resources

Documentation: Python API description, installation, examples, and usage information.
Example notebooks: Jupyter notebooks with practical examples.

Example scripts

These examples demonstrate some of the Python API.

Calculation of the image structure function and its azimuthal average:

import fastddm as fddm

file_names = [...]  # define here your list of image file names 
images = fddm.read_images(file_names)

pixel_size = 0.3    # um
frame_rate = 50     # frames per second
    
# compute image structure function and set experimental parameters
dqt = fddm.ddm(img_seq, range(1, len(img_seq)))
dqt.pixel_size = pixel_size
dqt.set_frame_rate(frame_rate)

# compute the azimuthal average
aa = fddm.azimuthal_average(dqt, bins=dqt.shape[-1] - 1, range=(0.0, dqt.ky[-1]))
