After using Ncorr, how should we extract the x, y, displacements, strains and correlation coefficients from the contour plots ?
Hello! Recently I am getting the error stated in the title, when I try to load data I have already saved via Ncorr and then I have to re-run the analysis to get to the contour plots. Does anyone have the same problem and could suggest a solution?
Thank you in advance.

After loading the data from ncorr post to ncorr post CStools, I encountered a problem related to colormap. The error comes in caxis (line 108), where it gives me a message like this: "Error using caxis (line 108) must be a two-element row vector," whereas I have followed all the steps of the manuals from YouTube. Please help me figure out how to sort out this problem.
This isn't really an issue in the code, but more of request.
Do you plan on updating Ncorr to be able to plot the Lagrangian strain on the current image? This would greatly increase users' ability to present data to audiences.
How could I output the displacement gradients such as du/dx and du/dy? I need them to compute cauhy strain.
Hi
I was trying to compile ncorr on visual studio 2019.
But there is an error in code!
How can I fix it?
Threre are several places in code with this issue
template <typename T_container>
inline typename sub_iterator<T_container>::sub_iterator& sub_iterator<T_container>::operator++() {
this->chk_valid_increment();
// increment sub_p, then determine position from it
++sub_p;
this->p = this->A_ptr->sub2ind(sub_p % sub_h + r_sub1_2D.first, sub_p / sub_h + r_sub2_2D.first);
return *this;
}
and the error is :
overloaded function "ncorr::details::sub_iterator<T_container>::sub_iterator" is not a type name
I am a student from Aalborg university, and my group and I has as part of a project created "support" program for processing a large amount of data in NCORR.
And as part of this we would like the capability of opening NCORR preloaded with the video that the support program formats to frames.
I am able to load both the reference and the roi image, but I am having difficulties loading the current images. I have tried a few things but cant find any documentation on how the matrix should be formatted.
We recently uploaded it to Github if it has any interrest:
https://github.com/Krille945/Image-sequencer-for-NCORR
Hope that you are able to help with this.
Sincerely,

Hello,
I have been using ncorr around 2 years, but today what i realized that my department will no longer make matlab available for students. Is there any way to run ncorr without matlab ? Thanks
Hi Justin Blaber,
I am Dongdi Yin from Southwest Jiaotong University. We are working on HRDIC based on SEM. We have got very nice strain maps using Ncorr for small size SEM images (up to 6749x5229 pixels). However, when we tried to analyze larger size SEM images, such as 8818x6871 pixels, an error occurred, which seems a run out of memory error. The screenshot of the error message is attached below.
We are using MATLAB 2021b. 20 cores are set for the OpenMP multithreading.
The computer we used: Intel® Xeon® Gold 6230R Processor (35.75M Cache, 2.10 GHz, 26 cores)+192GB DDR4 memory.
Many thanks and Happy New Year!
Looking forward to hearing from you
Kind regards
Dongdi Yin
Hi Justin,
Wondering if it would be possible to perform the DIC only in a horizontal (u) direction to improve the computation time. I've applied image rectification prior to uploading them onto the reference and current image so that they are horizontally aligned, such that only u-displacement map is necessary. How would we go about executing this?
This happens in Matlab 2017b and Ubuntu 16.04. Solution is to use LD_PRELOAD
before calling Matlab:
LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6 /usr/local/MATLAB/R2017b/bin/matlab
Can this theoretically work in Octave? This might be good to boost the utility
of your program in the open software universe.
I tried to run this in Octave by following the manual, but I encountered errors.
handles_ncorr = ncorr;
parse error near line 3356 of file /home/jerome/github/ncorr_2D_matlab/ncorr.m
syntax error
function [handle_name,outstate] = gui_sethandle(pos_parent)
Dear Blaber:
Recently I learned your 2D-DIC matlab software-ncorr,and I watch your video,but after I watch the "2D Digital Image Correlation using Ncorr -MATLAB- - Tutorial -PART 2",I find your Ncorr_post matlab software is a very useful tool.I search it in the web,but I didn't find it.I especially need it now,can you send it to me by email?
Thanks a lot!!!
Although I have installed PCT toolbox and openmp configurations seems to be fine, as I run handles_ncorr = ncorr
, I get this error:
Files compiled, but it was determined that OpenMP
is not actually supported. Please reinstall Ncorr in
single threaded mode or use a compiler which
supports OpenMP
Please see that all commands are successful.
