Object members

Measurement name	Description	Element type	Indexing	Physical Information
area	The area, expressed in world coordinates given by the input image calibration.	Floating point	[time]	AREA
pixelCount	The area in pixels; that is, the number of object pixels.	Unsigned integer	[time]	COUNT
areaFraction	The number of object pixels divided by the total number of pixels of the input image.	Floating point	[time]	FRACTION

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.
