alignment

If you have different volume or projection dimensions you might need to perform some alignment in order to process stitching.

alignment on projections

For z-stitching on projections, you can align projections along axis 1.

Possible alignments are 'center', 'left' and 'right'.

Here are examples of alignment along axis 2. In the following examples we have two datasets with the same frame width (red) and one dataset with a smaller width (blue).

'left' alignment

'right' alignment

'center' alignment

alignment on reconstructed volumes

For z-stitching on reconstructed volumes you can align projections along axis 1 and axis 2.

Possible alignments along axis 2 are the same as for alignment on projections ('center', 'left', 'right'). Along axis 1 valid values are 'center', 'back', 'front'.

Here are examples of alignment along axis 1 and axis 2. In the following examples we have two volumes with the same shape (in blue) and one 'smaller' volume (in red).

Note: The padded data are not illustrated in the drawing to ease understanding, but you can easily imagine them.

'front' alignment along axis 2 (and left along axis 1)

'back' alignment along axis 2 (and left along axis 1)

'center' alignment along axis 2 (and left along axis 1)

'center' alignment along axis 2 (and right along axis 1)

'center' alignment along axis 2 (and center along axis 1)
