Package tritechgemini.detect

Class TwoThresholdDetector

java.lang.Object

tritechgemini.detect.TwoThresholdDetector

All Implemented Interfaces:

RegionDetector

Direct Known Subclasses:

DetectedRegion

public class TwoThresholdDetector
extends Object
implements RegionDetector

Detector which searches for detected regions in data. Uses two thresholds, a "minimum maximum" (thHigh) and a "minimum edge" thLow. Should ideally be sent data after background subtraction, can also work with raw raw data.

Method Details

getMinObjectSize

public double getMinObjectSize()

Returns:

the minObjectSize

setMinObjectSize

public void setMinObjectSize(double minObjectSize)

Specified by:

setMinObjectSize in interface RegionDetector

Parameters:

minObjectSize - the minObjectSize to set

getMaxObjectSize

public double getMaxObjectSize()

Returns:

the maxObjectSize

setMaxObjectSize

public void setMaxObjectSize(double maxObjectSize)

Specified by:

setMaxObjectSize in interface RegionDetector

Parameters:

maxObjectSize - the maxObjectSize to set

detectRegions

public ArrayList<DetectedRegion> detectRegions(SonarImageRecordI rawGeminiRecord,
 SonarImageRecordI denoisedRecord,
 int thHigh,
 int thLow,
 int nConnect)

Search for regions using the raw data within the record

Specified by:

detectRegions in interface RegionDetector

Parameters:

rawGeminiRecord - Raw data record

denoisedRecord - Data with background removed.

thHigh -

thLow -

geminiRecord -

Returns:

detectRegions

public ArrayList<DetectedRegion> detectRegions(SonarImageRecordI denoisedRecord,
 byte[] recordData,
 int thHigh,
 int thLow,
 int nConnect)

Search for regions using a different set of raw data, which should probably be a noise reduced version of what was in the original record. Must be the same dimension as that in the original.

Parameters:

denoisedRecord -

recordData -

thHigh -

thLow -

Returns:

getConnectionTypes

public static int[] getConnectionTypes()

Get types of available connection

Returns:
