Soon: Ensemble correlation!

I am currently working on the implementation of ensemble correlation.

This kind of correlation averages the correlation matrices of a frame series before searching for a peak. Using it makes sense, when there a only a few particles visible in the flow. This is often the case in micro-piv, and I hope that there will be many users that benefit from this feature.

The changes to the GUI are finished, and I have a simple 1-pass ensemble correlation running. But I want to have the full potential of multi-pass window deformation algorithms with ensemble correlation. Implementation therefore takes a bit more time as there are some changes that challenge my brain. Additionally, most of the programming currently happens single handed because of my third daughter...

Slow & cozy programming...

Forum added

Hi, due to the increasing amount of PIVlab users and questions, I enabled a forum in this blog where questions can be asked. I am hoping that this can act as a central place for all comments and questions and that I can reply faster to questions without forgetting some of them...
I disabled the comments temporarily to see if the forum could work....

PIVlab direct download

Hi everybody! For those who do not want to register on the Matlab website in order to download PIVlab, I added a direct link to the zip archive (see the column on the right side). You can also click here to get the zipped PIVlab toolbox:

There were no updates of PIVlab since quite a while. The reason is that I am currently not working with particle image velocimetry after I finished my PhD. That is a pity. But the good thing is that I converted one of my other hobbies into a profession: Since 2014, I am working as a mechanical design engineer at TobyRich GmbH. Over there, I am responsible for the design of fixed-wing drones, which is - similar to doing PIV - a lot of fun.
I am sorry that (in most cases) I can not react to your emails or forum entries. My life is currently filled up with too many other things that require my attention.
Success with your analyses!!
