getLabelDefinitions
Get label definitions in labeled signal set
Description
returns a vector of lbldefs
= getLabelDefinitions(lss
)signalLabelDefinition
objects with the
labels of the labeled signal set lss
.
Changing lbldefs
does not affect the labeled set. To modify label
definitions, use editLabelDefinition
,
addLabelDefinitions
, and
removeLabelDefinition
.
getLabelDefinitions(
returns a vector of lss
,Name=Value
)signalLabelDefinition
objects that have a label type
and frame policy equal to the values you specify using name-value arguments.
Examples
Get Label Definitions
Load a labeled signal set containing recordings of whale songs.
load whales
lss
lss = labeledSignalSet with properties: Source: {2x1 cell} NumMembers: 2 TimeInformation: "sampleRate" SampleRate: 4000 Labels: [2x3 table] Description: "Characterize wave song regions" Use labelDefinitionsHierarchy to see a list of labels and sublabels. Use setLabelValue to add data to the set.
Retrieve the definitions of the labels in the set.
dfs = getLabelDefinitions(lss); for k = 1:length(dfs) dfs(k) end
ans = signalLabelDefinition with properties: Name: "WhaleType" LabelType: "attribute" LabelDataType: "categorical" Categories: [3x1 string] DefaultValue: [] Sublabels: [0x0 signalLabelDefinition] Tag: "" Description: "Whale type" Use labeledSignalSet to create a labeled signal set.
ans = signalLabelDefinition with properties: Name: "MoanRegions" LabelType: "roi" LabelDataType: "logical" ValidationFunction: [] ROILimitsDataType: "double" DefaultValue: [] Sublabels: [0x0 signalLabelDefinition] Tag: "" Description: "Regions where moans occur" Use labeledSignalSet to create a labeled signal set.
ans = signalLabelDefinition with properties: Name: "TrillRegions" LabelType: "roi" LabelDataType: "logical" ValidationFunction: [] ROILimitsDataType: "double" DefaultValue: [] Sublabels: [1x1 signalLabelDefinition] Tag: "" Description: "Regions where trills occur" Use labeledSignalSet to create a labeled signal set.
Input Arguments
lss
— Labeled signal set
labeledSignalSet
object
Labeled signal set, specified as a labeledSignalSet
object.
Example:
specifies a two-member set of random
signals containing the attribute labeledSignalSet
({randn(100,1)
randn(10,1)},signalLabelDefinition('female'))'female'
.
Name-Value Arguments
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN
, where Name
is
the argument name and Value
is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Example: getLabelDefinitions(lss,LabelType="roiFeature",FrameSize=50,FrameOverlapLength=5)
returns signalLabelDefinition
objects that contain
roiFeature
labels which have a frame size equal to 50 and a frame
overlap length equal to 5.
LabelType
— Label type
"attribute"
| "roi"
| "point"
| "attributeFeature"
| "roiFeature"
Label type, specified as "attribute"
, "roi"
,
"point"
, "attributeFeature"
, or
"roiFeature"
.
Example: LabelType="attribute"
Data Types: char
| string
FrameSize
— Frame size
numeric scalar
Frame size, specified as a numeric scalar. To enable this argument, set
LabelType
to "roiFeature"
.
Example: LabelType="roiFeature",FrameSize=50
Data Types: double
FrameOverlapLength
— Frame overlap length
numeric scalar
Frame overlap length, specified as a numeric scalar. To enable this argument, set
LabelType
to "roiFeature"
. You cannot
specify FrameOverlapLength
and FrameRate
simultaneously.
When you specify a frame overlap length, the function returns
signalLabelDefinition
objects that contain
roiFeature
labels that have FrameSize
and
FrameOverlapLength
equal to the values you specify.
Example: LabelType="roiFeature",FrameSize=50,FrameOverlapLength=5
Data Types: double
FrameRate
— Frame rate
numeric scalar
Frame rate, specified as a numeric scalar. To enable this argument, set
LabelType
to "roiFeature"
. You cannot
specify FrameRate
and FrameOverlapLength
simultaneously.
When you specify a frame rate, the function returns
signalLabelDefinition
objects that contain
roiFeature
labels that have FrameSize
and
FrameRate
equal to the values you specify.
Example: LabelType="roiFeature",FrameSize=50,FrameRate=45
Data Types: double
Output Arguments
lbldefs
— Signal label definitions
signalLabelDefinition
object
Signal label definitions, returned as a signalLabelDefinition
object or a
vector of such objects.
