Physical Information
volumeFraction
The proportion of pixels or voxels having the related label.
Floating point
[label, time]
FRACTION
volume
The area or volume represented by the related label, expressed in world coordinates.
Floating point
[label, time]
UNKNOWN
totalVolume
The area or volume of the mask image foreground, expressed in world coordinates. If no mask is provided, this measurement corresponds to the entire image.
Floating point
[label, time]
UNKNOWN
voxelCount
The number of pixels or voxels having the related label.
Integer
[label, time]
COUNT
totalVoxelCount
The number of pixels or voxels contained in the mask image foreground. If no mask is provided, this measurement corresponds to the entire image.
Integer
[label, time]
COUNT
sliceIndex
The index of the related slice (for time series).
Unsigned integer
[label, time]
COORDINATE
label
The label associated with the input index. Generally, index 0 corresponds to label 1.
Unsigned integer
[label, time]
INDEX
Object methods
Method
Description
void toDataFrame()
Convert the measurement to an IOLink.DataFrame
One or more "index" columns will be added at the beginning of the dataframe to identify
the different elements. For instance:
index [label]: The index of the label. This index systematically starts from 0
and is the label value minus 1 when all label values are represented.
When there are some missing label values, the corresponding label value cannot be
directly deduced from this index.
index [time]: The sequence index of a time series or of an image stack.
