Useful documentation can also be found at. For documentation on specific funcitons of ImageJ/Fiji, follow the links on this website to Documentation then ImageJ Documentation Wiki. ImageJ/FIJI Online Documentation and TutorialsĪlso under this Help menu, you can find a link to the ImageJ Website which has helpful information on ImageJ/FIJI. Select Close when you have finished managing your update sites then continue with your FIJI update as above. Select the site you want to change by ticking the checkbox next to the name, then click Add Update Site to include updates from this website in the current and all furute updates, or Remove to stop using this site for updates. Both are open source image analysis software packages, available to download for free. This will open a list of all available websites assoaciated with ImageJ/FIJI and their plugins. FIJI and ImageJ are very similar and for most functions are interchangeable. To do this select Manage Update Sites from the Updater Window when it appears. Specific sites can be included (ie: to use a specific plugin, you may need to add their website to updates) or removed (ie: a site from a plugin you no longer use and have uninstalled) from your updates. Again, you will need to restart FIJI once this process is completed. FIJI will then run through the same update steps as above. You can also run a manual update in FIJI. Extended periods without running the updater may result in FIJI no longer functioning correctly. Note: It is recommend that you always run the updater when it pops up. Select OK, then close and close and restart FIJI. Once the updates have been installed you will be asked to restart the program. To do this simply click Apply Changes at the bottom of the updater box, without selecting anything from the list.įIJI will then run through the list and apply all updates. You can highlight specific updates you want to apply, but it is recommended that you apply all updates every time. To allow the updater to run, select Yes, please from the drop down menu and click OK.įIJI will then automatically search for updates to the program and pluguin packages.Īvailable updates will be displayed in a list. Downloading FIJIįIJI downloads for PC and Mac can be found here: UpdatesįIJI has a built in auto-update function which will run, as required, upon opening the program. As such, some things may differ if you are using ImageJ. Our workshops focus specifically on FIJI, rather than ImageJ. FIJI also has an auto-update function that ImageJ does not have, and for advanced users is more user firendly and compatible for Macro writting. Plugins Fiji features thousands of plugins that aid in scientific image processing and analysis. The main difference between FIJI and ImageJ is that FIJI comes pre-bundled with a number of useful plugins which would require separate download and installation in ImageJ. Free & Open Source Like ImageJ itself, Fiji is an open source project hosted on GitHub, developed and written by the community. FIJI and ImageJ are very similar and for most functions are interchangeable. So, describing which method you use-and/or showing a comparison with other methods-is probably the best you can do to enable a statement on the quality of the extraction.įor more detailed information on thresholding and image segmentation basics and some quality evaluation see the Principles page.FIJI stands for " Fiji Is Just ImageJ". But such a ground truth is not naturally existing and is always created in one or the other way by a human. The basic problem of deciding if a threshold (or in general an extraction method) is “good” needs a “ground truth”. It will always be, to some extent, in the eye of the user/observer/scientist and will also be impacted by empirically collected knowledge. FAQ How do I know whether my threshold is correct? The ImageJ Ops project provides algorithms for both global and local thresholding. Local thresholding techniques adapt the threshold value on each pixel to the local image characteristics. Documentation for the threshold command.ImageJ provides several built-in methods for automatically computing a global threshold. Global thresholding works by choosing a value cutoff, such that every pixel less than that value is considered one class, while every pixel greater than that value is considered the other class. Thresholding is a technique for dividing an image into two (or more) classes of pixels, which are typically called “foreground” and “background.” Global thresholding If you’d like to help, check out the how to help guide!
