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.

Tools

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

To Do

Rebuild shape 3.7

Get RMS for each ZMAP

Run PreSurvey CompareOBJ

Example (old)

formal uncertanity 0.5179

RMS 1.447

RMS w/ TR 1.046

DiffShape 1.771

The 1st column is a list of 1. IMAGEFILES included in the landmark 2. overlaps with other landmarks 3. Limbs

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)
