Non rigid mc

function V = Non_rigid_mc(V, ref, opt)

Description

This function applies non-rigid motion correction to an input video using a multi-level registration approach. It constructs a pyramid of images (e.g., blood vessel and neuron projections) and applies log-domain demons registration to align frames while preserving fine details.

Warning

This code is experimental and may introduce undesired deformations when adjusting for non-rigid deformation.

Function Inputs:

Parameter Name	Type	Description
V	3D array	Input video as a height x width x frames array.
ref	Array	Reference image for initial alignment.
opt	Structure	Structure containing registration options.

Function Outputs:

Parameter Name	Type	Description
V	3D array	Motion-corrected video.

Example usage:

V_corrected = Non_rigid_mc(V, ref, opt);
