Feature freeze for 0.10
by Johannes Schönberger 16 Mar '14

16 Mar '14

Hi everyone, I suggest to stop merging new features at this moment until we release 0.10. There are lot’s of new features on the PR wait list, but merging them just before releasing 0.10 is imo not wise; we want a stable release. Let’s defer them for 0.11 and work hard to fix the remaining issues for 0.10. We already managed to make this list shorter: https://github.com/scikit-image/scikit-image/issues?milestone=3&state=open Johannes

robust ring (and circle) detection algorithm
by Eldad Afik 13 Mar '14

13 Mar '14

Dear Devs, In the process of tracking objects under the microscope I was confronted with an image analysis problem, for which I could not find a satisfactory solution in איק standard scientific packages (nor in the literature survey I made). At the time I started this, scikit-image did not include a circle Hough transform and OpenCV's was not good enough. I ended up developing an algorithm myself, which can be regarded as an off-spring of the circle Hough transform. I summarised the work in a manuscript titled: "*Robust and highly performant ring detection algorithm for 3d particle tracking using 2d microscope imaging*" (a pre-print is available at arXiv:1310.1371 <http://arxiv.org/abs/1310.1371>). NB, it was written minded at potential users and applications rather than computer scientists, which I am not. I would like to make the code publicly available. I believe it may be beneficial to the scikit-image community and users as a practical alternative to the current Standard Circle Hough transform. I contacted Stéfan van der Walt, who expressed interest in the algorithm. I would be grateful to have your feedback, any input would be helpful! With kind thanks to all contributors, Eldad -- Eldad Afik Physics of Complex Systems Weizmann Institute of Science *Some technical notes:* A* typical example *of the images I need to analyse can be found in the manuscript arXiv:1310.1371 <http://arxiv.org/abs/1310.1371> (Fig. 1a as well as S2a). The *results* of the software I wrote exhibit a detection rate which exceeds 94% and have only 1% false-detection, providing sub-pixel accuracy. The conceptual steps in making the algorithm* robust* are sketched in Fig. 2. The main steps to make it* efficient*, both in execution-time as well as memory consumption, are outlines on page 8; more technical details in this respect can be found in the "Supporting Information" Text section. The "methods" section of the manuscript provides some details regarding the *benchmarking*.

Going to need some Astropy magic for the data io (probably) and the Ra/Dec coordinate handling. Then we can use sklearn and potentially astroml once we have a detection routine? That sounds about right. Do you have ties to the AstroPy community? Perhaps someone there would be willing to lead the charge. Regards Stéfan

I don't have the time to coordinate a multi-Python project effort, but would gladly contribute. Agreed that ML will probably be required.
