You can find for example an OpenJDK 8 at OpenLogic, then install it, and when asked, check the box to select that it have to build a JAVA_HOME variable (replace a red cross symbole by a hard-disk symbol when asked, you’ll see it). You have to use ImageJ with a different JAVA version. Whether or not you understand this point, please follow the documented procedure to escape this. If you are a Windows user: there is specific issues between an external package ImageJ-ITK and the current JDK shipped with ImageJ. If not, go back to the Update Manager, and check that the repositories ImageJ-ITK, and Fijiyama are correctly selected.ĥ. Restart Fiji: a new Fijiyama entry should be available in the menu Plugins › Registration. In this list, activate ImageJ-ITK by checking the corresponding checkboxes.Īnd add the Fijiyama repository (by clicking on the button Add update site, and filling the fields : name = “/plugins/fijiyama”, site = ), then check the associated checkbox.Ĥ. Click on “OK” to close the first popup windows, then click on the button Manage update sites….ģ. Open Fiji, run the Update manager Help › Update. (if needed) Download and install Fiji from start Fiji, and let it automatically update. You have specific operations to run at the end of this section.ġ. In order to install Fijiyama on your computer, please follow these simple steps: To learn more about the algorithmic bases of the plugin, see section “The maths behind”. Algorithms from ITK and Simple ITK (Elastix algorithms) are available in the plugin as an option. In order to address the complex task of multi-modal registration, computation is based on the Block Matching algorithm (Ourselin et al., 2000), a generic purpose registration algorithm, developed in the field of medical imaging. Transformation of a 3D image (or a 4D / 5D hyperimage) with an ITK transformation.Composition of successive ITK transformations into a single transformation. ![]() N-times / M-modalities 3D series registration.Two images registration (training / settings mode).The following video shows an example of Fijiyama application: the registration of two stacks of MRI 3D images, collected on a grapevine cutting at different dates(see the “Training tutorial” for details). It has been tested on the most common imaging approaches in biology and medicine: MRI, X-rays, photography…Ī comprehensive dataset can be found at this link on dryad. Versatility: Fijiyama is a generic tool, efficient at any scale, tissue or imaging modality. ![]() After registration, stacks are combined in a coherent multi-modal and/or multi-time volume that can be explored using the ImageJ viewer. Goal: Fijiyama aims to address these issues by helping users to register, align and combine multi-modal 3D images or time-series in a unique reference geometry. ![]() In this situation, structures and phenomenon analysis can be compromised. In addition, as each modality highlights different structures, images from multiple devices can be very dissimilar. Fixing this misalignment in 2D is difficult and become intractable in 3D.
