ComponentMeasurements |  |
ComponentMeasurements computes the values of property prop for each component of a label matrix m that consists of identical elements. |
ComponentMeasurements uses the connectivity of nonzero pixels in image to compute the label matrix. |
ComponentMeasurements uses pixel values of image to compute property prop. |
ComponentMeasurements only returns measurements that satisfy a criterion crit. |
returns an expression of the form 
, where the 
are the values of 
computed for segment i.
computes multiple properties.
gives the names of all available properties as a list of strings.
False, ComponentMeasurements will ignore components that are connected to the border.
