Albert CardonaTrue as always that the way to make software run faster is to make it do less operations. After all, CPUs can only execute a fixed number of operations per unit of time.Here, I tweaked code for serial section registration that drops execution time from 27 seconds to 100 milliseconds: a 270x speed up.All it had to do is to search for matching SIFT features in one image only within a predetermined radius centered on one SIFT feature in another image. Extremely effective for when e.g., the maximum translation is known.The matching code using a KDTree: <a href="https://github.com/acardona/scripts/blob/master/java/asm/my/PointMatchesFast.java#L56" rel="nofollow noopener" translate="no" target="_blank">https://github.com/acardona/scripts/blob/master/java/asm/my/PointMatchesFast.java#L56</a>The test script: <a href="https://github.com/acardona/scripts/blob/dev/python/imagej/FIBSEM/tests/test_matchNearbyFeatures.py" rel="nofollow noopener" translate="no" target="_blank">https://github.com/acardona/scripts/blob/dev/python/imagej/FIBSEM/tests/test_matchNearbyFeatures.py</a><a href="https://mathstodon.xyz/tags/FijiSc" class="mention hashtag" rel="nofollow noopener" target="_blank">#FijiSc</a> <a href="https://mathstodon.xyz/tags/java" class="mention hashtag" rel="nofollow noopener" target="_blank">#java</a> <a href="https://mathstodon.xyz/tags/jython" class="mention hashtag" rel="nofollow noopener" target="_blank">#jython</a> <a href="https://mathstodon.xyz/tags/volumeEM" class="mention hashtag" rel="nofollow noopener" target="_blank">#volumeEM</a> <a href="https://mathstodon.xyz/tags/vEM" class="mention hashtag" rel="nofollow noopener" target="_blank">#vEM</a>

I am not claiming it is right that we allow that, nor that it makes OR the right tool for your job!

Albert CardonaFor an introduction to <a href="https://qoto.org/tags/FijiSc" class="mention hashtag" rel="nofollow noopener" target="_blank">#FijiSc</a> from the comfort of <a href="https://qoto.org/tags/python" class="mention hashtag" rel="nofollow noopener" target="_blank">#python</a> (or rather, <a href="https://qoto.org/tags/jython" class="mention hashtag" rel="nofollow noopener" target="_blank">#jython</a> 2.7), see my online tutorial, walking you through image processing concepts with working code that you can copy-paste into the Script Editor, which has code autocompletion to facilitate class and method discovery across the many libraries: <a href="https://syn.mrc-lmb.cam.ac.uk/acardona/fiji-tutorial/" rel="nofollow noopener" target="_blank">https://syn.mrc-lmb.cam.ac.uk/acardona/fiji-tutorial/</a>
