History
Description
This program creates an auto registration group template for applications
such as "coreg", "pointreg", "qnet", "findrx", and other ISIS software
with a pattern matching component. Given a specific algorithm name, it will
create that specific algorithm group template. If a tolerance is specified,
the application will automatically insert the tolerance keyword and value into
the auto registration template. The user must enter values for the
chip sizes of both the pattern and search chips.
It is highly recommended that users review the Pattern Matching document (in
the "Related Objects and Documents" section). This is where you will find the
available auto registration algorithms.
NOTE: This program lacks updates for the Gruen pattern matching algorithm.
In the future, this program will be deprecated and replaced with a wizard
(expert system) which will help guide the user in the selection of the
appropriate algorithm and parameter values.

Examples
Example 1
Create an auto registration template with all defaults.
Description
This example shows how the autoregtemplate application works, and how
to create a simple AutoReg template. Here, only the required parameters
have been entered. Because SubpixelAccuracy is "true" by default, there
is a SurfaceModel group in the output PVL containing the default
DistanceTolerance and WindowSize.
Object = AutoRegistration
Group = Algorithm
Name = MaximumCorrelation
Tolerance = 0.7
SubpixelAccuracy = True
End_Group
Group = PatternChip
Samples = 15
Lines = 15
End_Group
Group = SearchChip
Samples = 31
Lines = 31
End_Group
Group = SurfaceModel
DistanceTolerance = 1.5
WindowSize = 5
End_Group
End_Object
End
The above output is the text file resulting when the following
command line is run:
Command Line
autoregtemplate
algorithm=MaximumCorrelation tolerance=0.7 psamp=15 pline=15
ssamp=31 sline=31 topvl=out.txt
Run autoregtemplate with an algorithm name, tolerance, output file
name, and search and pattern chip sizes.
Example 2
Create an auto registration template without Subpixel Accuracy and with Chip
Interpolator specified.
Description
This example shows the process and results of creating an auto registration
template that disables calculating to subpixel accuracy. All the
parameter values from the previous example are left the same, except
that the SUBPIXELACCURACY keyword is set to "false". As a result,
there is no SurfaceModel PVL group, and none of those keywords may be
entered. Notice, the INTERP parameter is not specified in the
command line. Thus, the default cubic convolution type of interpolator
is used to load chips.
Object = AutoRegistration
Group = Algorithm
Name = MaximumCorrelation
Tolerance = 0.7
SubpixelAccuracy = False
ChipInterpolator = CubicConvolutionType
End_Group
Group = PatternChip
Samples = 15
Lines = 15
End_Group
Group = SearchChip
Samples = 31
Lines = 31
End_Group
End_Object
End
The above output is the text file resulting when the following
command line is run:
Command Line
autoregtemplate
algorithm=MaximumCorrelation tolerance=0.7 subpixelaccuracy=false
psamp=15 pline=15 ssamp=31 sline=31 topvl=out.txt
Run autoregtemplate with an algorithm name, tolerance, output file
name, search and pattern chip sizes, specified chip interpolator, but
no subpixel accuracy computation.
Example 3
Create an auto registration template specifying every parameter.
Description
This example shows the kinds of values one might potentially enter for
every valid keyword in an auto registration template. Every parameter is
specified in the template for this example. The only parameter not
specified in the command line is subpixel accuracy, which must remain at
its default ("true") in order to have a SurfaceModel group in the output
PVL. Interp is set to the nearest neighbor chip interpolator type.
Object = AutoRegistration
Group = Algorithm
Name = MinimumDifference
Tolerance = 0.7
ReductionFactor = 2
SubpixelAccuracy = True
ChipInterpolator = NearestNeighborType
End_Group
Group = PatternChip
Samples = 15
Lines = 15
ValidMinimum = 1200
ValidMaximum = 2800
MinimumZScore = 0.5
ValidPercent = 75.0
End_Group
Group = SearchChip
Samples = 31
Lines = 31
ValidMinimum = 1200
ValidMaximum = 2800
SubchipValidPercent = 80.0
End_Group
Group = SurfaceModel
DistanceTolerance = 2.5
WindowSize = 11
End_Group
End_Object
End
The above output is the text file resulting when the following command
line is run:
Command Line
autoregtemplate
algorithm=MinimumDifference tolerance=0.7 reductionfactor=2
interp=nearestneighbor psamp=15 pline=15 pmin=1200 pmax=2800
pvalidpercent=75 ssamp=31 sline=31 smin=1200 smax=2800
minimumzscore = 0.5 ssubchipvalidpercent = 80 distancetolerance=2.5
windowsize=11 topvl=out.txt
Run autoregtemplate with all parameters specified by the user.

Updated documentation
|
Kimberly Oyama | 2012-10-03 |
Removed the ECCENTRICITYRATIO, ECCENTRICITYTESTING, RESIDUALTESTING, and RESIDUALTOLERANCE
parameters because they are no longer used due to the new sub-pixel registration algorithm
that has replaced the previous surface model algorithm. Also because of the new algorithm,
the minimum windowsize was changed from 3 to 5. The CHIPINTERPOLATOR parameter has been
removed and the INTERPOLATORTYPE parameter has been renamed INTERP. The TO parameter has
been changed to TOPVL. The references to the AutoReg class have been rewritten for better
user understanding and helpful documentation has been added for some parameters. The
documentation has been updated to reflect these changes. Fixes #1043.
