Introduction

Bob created a suite of programs that handles linescan (push broom) images.

Here are notes about how it works and what we've learned.

displayX

displayX serves the same purpose as display. Users can view images, which can be helpful for adjusting thresholds, treating blemishes, seeing landmark locations, and so forth. The options in display and displayX are similar, except that in displayX the user is not given the option to "show limb? (y/n)". The outputs of displayX and display are also similar. Users can look at TEMPFILE.pgm to see the image. Terminal will report the size of the image, as well as T1, KS, etc. and give the option to copy TEMPFILE.pgm to ./Display/imagenameR.pgm.

registerX

registerX serves the same purpose as register. Users can register images to another image, to a map, or to a shape. registerX has fewer options than register. Specifically, registerX has the following options:

1. Quit
2. Change scale
3. Global shift
4. Shift unknown (LEFT/RED) image
5. Change reference
6. Change RANGE of (LEFT/RED) image
7. Revert to nominal
8. Change substrate (f)
9. Turn on bkg b. Turn on image for Vlm c. Change correlation limit = 0.25 d. Unfix scobj (this is NOT the same as option d in register!)

The following options exist in register, but not registerX.

• b. Set a big correlation
• Rotate unknown (LEFT/RED) image
• Update nominal and quit P. Pole search N. New pole and nominal relative phase R. Rotate body F. Features to body rotation S. Change image stretch
• Update illumination G. Get approach range from images O. Find OMEGA W. Write log l. Turn on log d. Fix scobj e. Fix pointing v. Fix center t. Tuck picture

RegisterX also does not list the current picture, current reference, or current scale at the bottom of the menu, but register does.

The outputs of register and registerX are the same: TEMPFILE.pgm and TEMPFILE.ppm that can be used to assess how well the image is registered. See the documentation for register for more details on these files.

• lithosX (lithospX does not work, so landmarks with linescan images must be processed serially, which means iterations can take a while).

• autoregisterX

• residualsX

• geometryX

• mosaic -- While not an X-file-only tool, is heavily used to support data processing

In addition to Bob's software, Terik and Carolyn modified some other programs so that they work with the X versions of the software:

• make_scriptTX

• make_scriptRX

• make_scriptAX

• make_scriptX

• find_nofitTX

• find_nofitX

Specific Object (includes PROCESS_<whatever>)

• LRO_setup -- What is needed to make LRO work

• PROCESS_HIRISE
• PROCESS_HRSC

Specific Projects

• Tsiolkovsky -- First project

• Ingiini - Evaluation of topography of the lunar swirls

Building Photometic Cubes

A Photometric cube is a abstraction of a physical location on a surface in which every image is registered to an SPC bigmap with backplanes.

  • phase.cub
  • i.cub
