EasyImage::BiLevelMorphoGradientBox

Computes the morphological gradient of a bilevel image using a rectangular kernel.

Namespace: Euresys::Open_eVision

[C++]

void BiLevelMorphoGradientBox(
   EROIBW8* sourceImage,
   EROIBW8* destinationImage,
   OEV_UINT32 halfOfKernelWidth,
   OEV_UINT32 halfOfKernelHeight
)

Parameters

sourceImage

Pointer to the source image/ROI.

destinationImage

Pointer to the destination image/ROI. If NULL (default), this operation is destructive (i.e. applied to the source image).

halfOfKernelWidth

Half of the box width minus one (by default, halfOfKernelWidth = 1; 0 is allowed).

halfOfKernelHeight

Half of the box height minus one (by default, same as halfOfKernelWidth; 0 is allowed).

Remarks

The morphological gradient is the difference between the dilation and the erosion of the image, using the same structuring element.
The kernel size is a pair of odd numbers; they must be halved before they are passed. For instance, a 3x5 kernel is passed as 1x2.
