This input cube is the cube that needs to be de-jittered. The algorithms used are designed for a rolling shutter instrument with an accompanying check line cube file (see main description). This cube file must be writable. Coefficients to adjust the jitter will be written to the cube labels for use by the rolling shutter camera model.

This input cube is the check line cube. It contains a set of lines that were repeatedly read from the sensor array interspersed with the readout of the main image data. ...EXPAND...

The parameter template to use for the auto registration process. The default template calls the Maximum Correlation pattern matching algorithm with predefined parameter values. There are other templates available in the system autoreg/template directory. Also, the user can use the 'autoregtemplate' application to create a new template file. Example minimal auto registration definition file:
Object = AutoRegistration Group = Algorithm Name = MaximumCorrelation Tolerance = 0.7 SubPixelAccuracy = True EndGroup Group = PatternChip Samples = 1391 Lines = 1 EndGroup Group = SearchChip Samples = 1399 Lines = 7 EndGroup Group = SurfaceModel WindowSize = 7 EndGroup EndObject

This is the scale of the image. Only use this parameter if you have enlarged the main cube. This will allow the program to access the correct normal cube line number based on the un-enlarged check table values. Enlarging the main image by 4x is used to assist the registration from becoming pixel locked (i.e., registering on the whole pixel value instead of a sub-pixel) Example: For a 4x enlargement set this value to 4.0.
