The values in all used stitching tools and settings deviate from the PTGui reference, thus indicating distortions. Panel (C) shows the percentage deviation of the obtained values compared to the PTGui reference values.
Five randomly selected vessels along a transect (see labels in B) having an lumen area between 1 µm 2 were subsequently measured using ROXAS (Table 1) using always the same settings in images stitched with the software PTGui, AutoStitch, Microsoft Image Composite Editor and Photoshop (Automatic and Reposition settings). The input images contained distortions introduced by the used optical system, which were successfully removed by PTGui (verified by creating a composite image of a stage micrometer and measuring the distances between tick marks, which yielded constant values throughout the image). The used overlap with neighboring images is visualized for one of the images with yellow dashed lines in (A).

Manual mode: full control over the final result Some benefits of PTGui, when compared to other stitching software:Īutomatic stitching: create panoramas with just a few mouse clicks Use PTGui to stitch any number of photos into a panoramic image. Originally developed as a Graphical User Interface for Panorama Tools (hence the name), PTGui now is a full featured photo stitching application. PTGui is panoramic stitching software for Windows and Mac OSX.
