9.38. ITK H Convex Image Filter
Identify local maxima whose height above the baseline is greater than h.
Group (Subgroup)
ITKMathematicalMorphology (MathematicalMorphology)
Description
HConvexImageFilter extract local maxima that are more than h intensity units above the (local) background. This has the effect of extracting objects that are brighter than background by at least h intensity units.
This filter uses the HMaximaImageFilter .
Geodesic morphology and the H-Convex algorithm is described in Chapter 6 of Pierre Soille’s book “Morphological Image Analysis: Principles and Applications”, Second Edition, Springer, 2003.* GrayscaleGeodesicDilateImageFilter , HMinimaImageFilter

Description |
|---|---|---|---|
Height |
Scalar Value |
Float64 |
Set/Get the height that a local maximum must be above the local background (local contrast) in order to survive the processing. Local maxima below this value are replaced with an estimate of the local background. |
Fully Connected |
Bool |
Set/Get whether the connected components are defined strictly by face connectivity or by face+edge+vertex connectivity. Default is FullyConnectedOff. For objects that are 1 pixel wide, use FullyConnectedOn. |
