stripe scoringStripe Score Tool

The Stripe Score Tool works as a stripe filtering tool.  It uses scores and weights to select a specific stripe from a collection of points.  

Understanding "Scores" and "Weights" for Stripe Scoring tools

The "weight" is the level of importance a characteristic will have when finding stripe end points.  The "score" is the overall level of similarity between the stripe points found by the tool, and the expected values defined by the user in the tool's parameters page.  

The weight is always based on 100%.  Consequently if one characteristic is given a weight of 2 and another 3 the first characteristic will be given a 40% importance level and the second, 60%.

Using the Stripe Score Tool

Drag a tool that defines a collection of points onto the "Points" section of the Stripe Score Tool's inputs page.  (Most often this will be the Stripe tool, for the stripe tool adds extra information concerning the relative positions of points that other tools do not.)  Use the dropdown menu to select "points".

The parameters page sets the stripe points polarity, the weights, max/min values and expected values.  

Polarity 1 and 2 sets which points will be considered for the first and second edge (respectively) based on polarity.  Polarity can be set to "Dark to Light", "Light to Dark", or "Don't Care".  If the polarity is set to "Dark to Light", for example, then only points that fall on an edge that is dark turning to light, according to the direction of the ROI box, will be considered.

WeightWidth sets the importance or "weight" of the width (distance) characteristic when finding edge points.

MinWidth sets the minimum width of a potential stripe.  In order for two points to score their distance from one another must be greater than the MinWidth.

MaxWidth sets the maximum width of a potential stripe.  In order for two points to score their distance from one another must be less than the MaxWidth.

ExpectedWidth is the value that will be used to score the width characteristic.  The closer the distance between two potential points is to the ExpectedWidth the higher their score.

WeightIntensity sets the importance or "weight" of the intensity (contrast of the edge) characteristic when finding edge points.
Note: Since intensity is the contrast from dark to light it has a maximum range of 255.

MinIntensity sets the minimum intensity of a potential edge.  In order a point to score its intensity must be greater than the MinIntensity.

MaxIntensity sets the maximum intensity of a potential edge.  In order a point to score its intensity must be less than the MaxIntensity.

ExpectedIntensity is the value that will be used to score the intensity characteristic.  The closer the intensity a points has to the ExpectedIntensity the higher its score.

WeightPosition sets the importance or "weight" of the position (the points relative location within the ROI used to define the points) characteristic when finding edge points.

PositionAsPercent when checked, defines the position of the points as a percentage within the ROI.  When unchecked the position will be defined in terms of pixels.  

MinPosition sets the minimum position of a potential edge.  In order for a point to score its position must be greater than the MinPosition.

MaxPosition sets the maximum position of a potential edge.  In order for a point to score its position must be less than the MaxPosition.

ExpectedPosition is the value that will be used to score the position characteristic.  The closer the position a points has to the ExpectedPosition the higher its score.

When the tool is run the results are listed in the parameters page.  The score for Width, Intensity and Position are listed individually, and the combined score is given in the Score box.  The parameters page also lists the Distance, Intensity and Position of the highest scoring stripe.
