Show Data Pieces

Various information sets are loaded with the original data or created during processing. You can any time access them via Show Menu.

Log

Menu Show → Log.

Short information notes are deposited here after any processing step.

Metadata

Menu Show → Metadata.

In case the original data consisted of metadata dictionary, that will be displayed here.

Stick

Menu Show → Stick.

A user may create so-called sticking points to guide processing, i.e. coordinates of supposedly identical locations in images of the original and rotated orientaitons. These sticking points can be created before linear correction, before non-linear corrections or before merging. They are stored independently and can be checked through this menu item.

Rigit shifts

Menu Show → Rigit shifts.

Some processing steps involve calculation of the x,y shifts between two rigit (undeformed) images. Those can be checked through this menu item.

Non-linear shifts

Menu Show → Non-linear shifts.

The non-linear correction evaluates the x/y shifts for each row of an image in the original orientation and for each column in the rotated orientation. Those can be accessed through this menu item.

Cross correlation

Menu Show → Cross correlation.

If "use FFT" switch on the control panel is OFF, the linear shift is evaluated from cross correlation between images in the original and rotated orientations. The correlation is displayed via this item in Menu. The maximum in the cross correlation is marked by a red circle.

FFT Images

Menu Show → FFT.

If "use FFT" option is selected in the switch on the control panel, the FFT images are used for evaluation of a linear distortions in images of both the original and rotated orientations. These images are displayed via this item in Menu. The spots actually used for distortion calclulation are marked by red and blue circles. Note that their symmetric counterparts are not marked but actually used in evaluation for better precision.

Convergence

Menu Show → Convergence.

Non-linear correction is the iterative process reducing the average required shift with each forthcoming iteration. This normally should converge to a quite small (although not neccesary zero) value. You can always a posteriori check convergence via this menu item.
