ITKHConvexImage
===============
Group (Subgroup)¶
ITKImageProcessing (ITKImageProcessing)
Description¶
Identify local maxima whose height above the baseline is greater than h.
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.

Parameters¶
| Name | Type | Description |
|---|---|---|
| Height | double | 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. |
| FullyConnected | 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. |
Required Geometry¶
