3D Alignment and Registration

Proper alignment of 3D electron microscopy image stacks is crucial for effective manual and automatic analysis. Overlapping regions are stitched together into a coherent dataset.

We offer a full service for the alignment of 3D electron microscopy datasets. Just upload the dataset and receive the results. No coding required.

● Dynamic mesh transformations for fine alignments
● Support for arbitrary shapes through masking
● Efficient global alignment with RANSAC
● Robust outlier (e.g. debris or artifacts) detection

2D In-Plane Stitching and Montages


Easily combine individual image tiles produced by your microscope into a single plane. Overlapping regions are stitched together with smart outlier rejection.
We offer a full service for the alignment of large-scale 2D electron microscopy or other images. Just upload the dataset and receive the results. No coding required.

Normalization and Gradient Correction

Due to the sensitive nature of image acquisition, some artifacts are inevitable. Sections may show uneven brightness and contrast. There may be gradients across tiles or throughout the dataset.
Fortunately, these artifacts can be corrected using our technology. As part of our alignment and stitching services or separately, we offer services for normalisation and gradient correction in large-scale datasets. 
● Histogram-based correction of tiles or sections● Gradient correction within a tile or across the stack

Stitching of 3D Tiles

Imaging large volumes with Micro-CT or Synchrotron X-Ray Tomography requires sub-dividing the volume into 3D tiles.
We offer services for stitching reconstructed tomography tiles into a coherent dataset.
● Stitch 3D volumes from Micro-CT or Synchrotron X-Ray sources● Seamless border blending
