◆ SetGradientFilterType()

void Isis::AutoReg::SetGradientFilterType ( const QString & gradientFilterType )

gradientFilterType the gradient filter type to use

Exceptions

iException::User - "Invalid Gradient type."

References _FILEINFO_, and Isis::None.

◆ SetPatternValidPercent()

void Isis::AutoReg::SetPatternValidPercent ( const double percent )

Set the amount of data in the pattern chip that must be valid.

For example, a 21x21 pattern chip has 441 pixels. If percent is 75 then at least 330 pixels pairs must be valid in order for a comparision between the pattern and search sub-region to occur. That is, both the pattern pixel and search pixel must be valid to be counted. Pixels are considered valid based on the min/max range specified on each of the Chips (see Chip::SetValidRange method).

If the pattern chip reduction option is used this percentage will apply to all reduced patterns. Additionally, the pattern sampling effects the pixel count. For example if pattern sampling is 50% then only 220 pixels in the 21x21 pattern are considered so 165 must be valid.

If this method is not called, the PatternChip ValidPercent defaults to 50 in the AutoReg object constructor.

See also: SetValidRange()

Parameters

percent Percentage of valid data between 0 and 100, default is 50% if never invoked

Exceptions

iException::User - "Invalid value for PatternChip ValidPercent."

References _FILEINFO_.

◆ SetPatternZScoreMinimum()

void Isis::AutoReg::SetPatternZScoreMinimum ( double minimum )

Set the minimum pattern zscore.

This option is used to ignore pattern chips which are bland (low standard deviation). If the minimum or maximum pixel value in the pattern chip does not meet the minimum zscore value (see a statisitcs book for definition of zscore) then invalid registration will occur.

If this method is not called, the z-score minimum defaults to 1.0 in the AutoReg object constructor.

Parameters

minimum The minimum zscore value for the pattern chip. Default is 1.0

Exceptions

iException::User - "Invalid value for PatternChip MinimumZScore."

References _FILEINFO_.

◆ SetReductionFactor()

void Isis::AutoReg::SetReductionFactor ( int factor )

Set the reduction factor used to speed up the pattern matching algorithm.

If this method is not called, the reduction factor defaults to 1 in the AutoReg object constructor.

Parameters

factor Reduction factor. Must be greater than or equal to 1.

Exceptions

iException::User - "Invalid value for Algorithm ReductionFactor."

References _FILEINFO_.

◆ SetSubPixelAccuracy()

void Isis::AutoReg::SetSubPixelAccuracy ( bool on )

If the sub-pixel accuracy is enabled, the Register() method will attempt to match the pattern chip to the search chip at sub-pixel accuracy, otherwise it will be registered at whole pixel accuracy.

If this method is not called, the sub pixel accuracy defaults to on = true in the AutoReg object constructor.

Parameters

on	Set the state of registration accuracy. The default is sub-pixel accuracy is on

◆ SetSubpixelPosition()

bool Isis::AutoReg::SetSubpixelPosition ( Chip & window )

protected

Set the search chip sample and line to subpixel values if possible.

This method uses a centroiding method to gravitate the whole pixel best fit to a subpixel extremum in the continuous image space. The weights of the centers of gravity in the centroiding algorithm are modeled by goodness of fit values within a discrete search window.

Parameters

window The search window extracted from the fit chip

Returns: bool Returns true if the subpixel solution is valid

◆ SetSubsearchValidPercent()

void Isis::AutoReg::SetSubsearchValidPercent ( const double percent )

Set the amount of data in the search chip's subchip that must be valid.

If this method is not called, the SearchChip SubchipValidPercent defaults to 50 in the AutoReg object constructor.

Parameters

percent Percentage of valid data between 0 and 100, default is 50% if never invoked

See also: SetPatternValidPercent()

Exceptions

iException::User - "Invalid value for SearchChip SubchipValidPercent."

References _FILEINFO_.

◆ SetSurfaceModelDistanceTolerance()

void Isis::AutoReg::SetSurfaceModelDistanceTolerance ( double distance )

Set a distance the surface model solution is allowed to move away from the best whole pixel fit in the fit chip.

If this method is not called, the distance tolerance defaults to 1.5 in the AutoReg object constructor.

Parameters

Exceptions

iException::User - "Invalid value for SurfaceModel DistanceTolerance."

References _FILEINFO_.

◆ SetSurfaceModelWindowSize()

void Isis::AutoReg::SetSurfaceModelWindowSize ( int size )

Set the surface model window size.

The pixels in this window will be used to fit a surface model in order to compute sub-pixel accuracy. In some cases the default (3x3) and produces erroneous sub-pixel accuracy values.

If this method is not called, the window size defaults to 5 in the AutoReg object constructor.

Parameters

size	The size of the window must be three or greater and odd.

Exceptions

iException::User - "Invalid value for SurfaceModel WindowSize."

References _FILEINFO_.

◆ SetTolerance()

void Isis::AutoReg::SetTolerance ( double tolerance )

Set the tolerance for an acceptable goodness of fit.

If this method is not called, the tolerance value defaults to Isis::Null in the AutoReg object constructor.

Returns a PvlGroup containing the PvlKeywords of the parameters this object was most recently run with.

Because of publically accessible mutators, AutoReg's runtime parameters can change, and this version of the template is designed to reflect the paramters it was actually run with, as opposed to simply initialized with. If no mutators were ever called externally, then this PvlGroup should be the same as the one received from RegTemplate().

Returns: PvlGroup The keywords this object was most recently run with

References Isis::Chip::Lines(), Isis::Chip::Samples(), and Isis::toString().

◆ WindowSize()

double Isis::AutoReg::WindowSize ( ) const
