coldftreg
This source code is a column-based version of DFT registration. It aligns every column of a matrix X to a reference vector V.
The amount of shift estimated between X and V and be used to align another matrix Y as well. Please run demo.m to see an example.
It is useful in applications like Optical Coherence Tomography where there is sweep-to-sweep variation of the signals (columns of X) due to laser instability.
Version history:
- v1.0: first implementation.
- v2.0: support the case where length(V) < size(X, 1). Add mean subtraction to improve stability. Handle a corner case where the number of rows in X and Y is odd.
Please report bugs with this code to thnguyn@mit.edu.
