Image registration

A python based tool for registering a template brain (from the Allen Reference Atlas) to the sample image, an extension of aMAP. Once this is complete, any other image in the template space can be aligned with the sample (such as region annotations, for segmentation of the sample image). The template to sample transformation can also be inverted, allowing sample images to be aligned in a common coordinate space. Current registration backend is niftyreg.

Component of BrainGlobe Initiative

Aligning Big Brains & Atlases (ABBA) is a set of software components which allows users to register images of thin serial biological tissue sections, cut in any orientation (coronal, sagittal or horizontal) to atlases, usually brain atlases. ABBA is available as a Fiji plugin for performing registration; a QuPath extension is also available and recommended. Typically, a set of serial sections is defined as a QuPath project, that is registered within Fiji. The registration results can then imported back into QuPath for downstream processing (cell detection and classification, cell counting per region, etc.).

Available atlases include the 3D mouse Allen Brain atlas and the Waxholm Space Atlas of the Sprague Dawley Rat Brain. Depending on your installation method, you may also access all BrainGlobe atlases.

Fast4DReg is a Fiji macro for drift correction for 2D and 3D video and is able to correct drift in all x-, y- and/or z-directions. Fast4DReg creates intensity projections along both axes and estimates their drift using cross-correlation based drift correction, and then translates the video frame by frame. Additionally, Fast4DReg can be used for alignment multi-channel 2D or 3D images which is particularly useful for instruments that suffer from a misalignment of channels.

Relate is a correlative software package optimised to work with EM, EDS, EBSD, & AFM data and images.  It provides the tools you need to correlate data from different microscopes, visualise multi-layered data in 2D and 3D, and conduct correlative analyses.

• Combining data from different imaging modalities (e.g. AFM, EDS & EBSD)

• Interactive display of multi-layer correlated data

• Analytical tools for metadata interrogation

• Documented workflows and processes

Correlate

• Import data from AZtec using the H5oina file format
• Import AFM data
• Correlate both sets of data using intuitive image overlays and image matching tools
• Produce combined multimodal datasets

Visualise

• 2D display of multi-layered data
• 3D visualisation of topography combined with AFM material properties, EM images, and EDS & EBSD map overlays
• Customisation of colour palettes, data overlays, image rendering options, and document display
• Export images and animations

Analyse

• Generate profile (cross section) views of multimodal data
• Measure and quantify data across multiple layers
• Analyse areas via data thresholding using amount of x-ray counts, phase maps, height, or other material properties.
• Select an extensive range of measurement parameters
• Export analytical data to text or CSV files

Correlia is an open-source ImageJ/FIJI plug-in for the registration of 2D multi-modal microscopy data-sets. The software is developed at ProVIS - Centre for Correlative Microscopy and is specifically designed for the needs of chemical microscopy involving various micrographs as well as chemical maps at different resolutions and field-of-views.
