Tile Sorter

Stitching & Alignment

Tile Sorter
Various applications require a process named stitching and alignment as a prerequisite step for the visualization of 3D or 4D volumetric files. Here, every plane of the resulting image is combined of a number of tiles acquired separately.
arivis Vision4D is the unique tool for effective stitching and alignment of hundreds to thousands of multiple single files (tiles), which may create volumes of several hundred gigabyte or even terabyte in total file size.
The arivis Tile Sorter allows for a complete interactive adjustment for stitching.
