This function performs schools detection in Echoview using COM scripting.
Usage
EVSchoolsDetect(
EVApp = NULL,
EVFile = NULL,
acoVarName,
outputRegionClassName,
deleteExistingRegions,
distanceMode,
maximumHorizontalLink,
maximumVerticalLink,
minimumCandidateHeight,
minimumCandidateLength,
minimumSchoolHeight,
minimumSchoolLength,
dataThreshold
)Arguments
- EVApp
=NULL An Echoview Application COM object
- EVFile
=NULL An Echoview file COM object
- acoVarName
A string containing the name of the acoustic variable to perform the analysis on
- outputRegionClassName
A string containing the name of the output region
- deleteExistingRegions
Logical TRUE or FALSE
- distanceMode
for schools detection (see Echoview help).
- maximumHorizontalLink
The maximum horizontal link in meters
- maximumVerticalLink
The maximum vertical link in meters
- minimumCandidateHeight
The minimum candidate height in meters
- minimumCandidateLength
the minimum candidate length in meters
- minimumSchoolHeight
The minimum school height in meters
- minimumSchoolLength

- dataThreshold
minimum integration threshold (units: dB re 1m^-1)
Value
a list object with four elements. $nbrOfDetectedschools, $thresholdData, $schoolsSettingsData, and $msg: message for processing log
