Error_evaluation
-
Processing States -- What are the states that a shape model goes through as it gets perfected.
-
Eval-point-cloud -- Using a point cloud for CompareOBJ rather than a full OBJ
-
Normalized Cross-Correlation Evaluation -- Normalized cross-correlation of images of the model and images of truth.
Here are a list of error evaluation tools and ideas
- formal uncertainty -- standard, bottom of the RESIDUALS.TXT. Contains the fit of all the landmarks and overlaps.
- Best 80% of landmarks. Taken from ?
- CompareOBJ
- CompareOBJ TR
- CompareOBJ --save-plate-error error
- diffShape and gnuplot delta.gpi
- SIGMAS.TXT plotted with sig.gpi
- 2D heat map plot of number of images in landmarks
- 2D heat map plot of residual errors for landmark
- 2D heat map plot of residual errors for images
- Evaluation of delta between truth S/C position and solved for S/C position: as an RMS
- 2D plot of delta between truth S/C position and solved for S/C position.
- Number of "issues" (or >>) in MAPINFO, PICINFO and RESIDUALS.TXT
- Rebuild shape 3.7
- Get RMS for each ZMAP
- Run PreSurvey CompareOBJ

The 2nd column is the error in deltaX (# pixels in image resolution) . The 3rd column is the error in deltaY (# pixels in image resolution) . The 4th column is the magnitude of the error (combines deltaX and deltaY) . The 5th column is the error in physical units (km) . ......................... . name val . (Bottom) .
