I never heard of RepeatedTiming. Thanks for that ;)

I just inserted it as a link to not confuse the question too much.

comment Efficient way to perform local Otsu thresholding on image
Thanks Silvia for this interesting approach. The problem with the CurvatureFlowFilter is that I also have objects in the image that are not circular. The structure of those gets distorted by the filter. As I said, I know about LocalAdaptiveBinarize, but local Otsu gives in many cases much better results (I tried this on images with ImageJ). That is why I am really looking for a implementation of it in Mathematica.

comment Why does this line increase the consumed memory?
I couldn't think of this straightforward solution, thanks :) However, I will report this memory leak as a bug to Wolfram support.

Not yet. I still think that I might do something wrong.

comment Why does this line increase the consumed memory?
Thanks. Never heard of the function Share before. I added it but it doesn't seem to have an effect... unfortunately...

comment Why does this line increase the consumed memory?
Could be an interesting idea, thanks. Unfortunately, I don't have version 9 installed to try that with another version than 10. I tried the code using UndoOptions but it doesn't seem to have any effect. Memory is still leaking...

comment Why does this line increase the consumed memory?
I applied it several times using Map and Table and the memory consumption raises in each iteration. If i would run it long enough it would certainly kill my computer (which it did already in the real program I use this line). So it never stops or returns the memory...

quite a bit of RAM available, yes. But at some point even 96 GB are gone ... ;)

comment Why does this line increase the consumed memory?
Thanks for your fast reply. No doesn't have any effect. I will add it directly. It seems that the filter just soaks up my memory ;)

comment How to combine TimeSeries of different dimensionality into TemporalData object?
Thanks for your update of the answer. That looks very promising!

comment How to combine TimeSeries of different dimensionality into TemporalData object?
Thanks for your advice. I will try to do it with the workaround. Do you have an idea if it is possible to do interpolation of values in between but to avoid extrapolation?

comment Is there a way to use video codecs for avi files in Mathematica?
I have the impression that the images appear much darker (maybe due to higher contrast) than in the avi files. But in fact I am not interested in the mov files. I would prefer avi.

comment How to find the local maximum of a list
I recommend that you post a list of example data or a file that can be downloaded such that other users can play around with it and develop solutions.

@Leonid Shifrin: sure, why not. I have unchecked your answer and keep it open for a while.

comment What is the fastest way to extract a substring from a huge string?
thanks very much! That piece of code looks perfect for my needs. I will have to test it on my data.

@AlbertRetey: Thanks very much for your fast comment (which is in fact the answer). You guess was totally right. Would you be so kind and post your comment as an answer?

comment Running out of memory when partitioning an image with ImagePartition
@bills: Thanks for the nice answer. Since my data is quite large, I will try it with the ImageFileFilter idea you proposed and see what comes out. I will add the results to the question.

comment Running out of memory when partitioning an image with ImagePartition
I added some information on the application of the function on my data in the question above.
