ImageDev

ObjectBoundaryArea

Measures the surface of objects contained in the volume of interest of a binary image.

Access to parameter description

For an introduction: This algorithm measures the surface area $S$ of solid objects. This algorithm takes into account the input image calibration (spacing) and returns thus results in world coordinates.

Parameters

Parameter Name Description Type Supported Values Default Value
input
inputBinaryImage
The input binary image. Image Binary nullptr
input
inputMaskImage
The binary image defining the volume of interest. The measurement is computed from pixels having a 1 value in this image. If it equals null, the computation is performed from all pixels of the input image. It must have same dimensions as the input image. Image Binary nullptr
output
outputMeasurement
The output measurement result. ObjectBoundaryAreaMsr nullptr
Parameter Name Description Type Supported Values Default Value
input
input_binary_image
The input binary image. image Binary None
input
input_mask_image
The binary image defining the volume of interest. The measurement is computed from pixels having a 1 value in this image. If it equals null, the computation is performed from all pixels of the input image. It must have same dimensions as the input image. image Binary None
output
output_measurement
The output measurement result. ObjectBoundaryAreaMsr None
Parameter Name Description Type Supported Values Default Value
input
inputBinaryImage
The input binary image. Image Binary null
input
inputMaskImage
The binary image defining the volume of interest. The measurement is computed from pixels having a 1 value in this image. If it equals null, the computation is performed from all pixels of the input image. It must have same dimensions as the input image. Image Binary null
output
outputMeasurement
