Morphology Operators

Mathematical morphology operations.

erode

cpp

GpuImage erode(const GpuImage& input, int kernelSize);

Applies erosion (shrinks white regions).

cpp

GpuImage dilate(const GpuImage& input, int kernelSize);

Applies dilation (expands white regions).

cpp

GpuImage morphologyOpen(const GpuImage& input, int kernelSize);

Opening: erosion followed by dilation. Removes small bright spots.

cpp

GpuImage morphologyClose(const GpuImage& input, int kernelSize);

Closing: dilation followed by erosion. Fills small dark holes.

cpp

GpuImage morphologyGradient(const GpuImage& input, int kernelSize);

Morphological gradient: difference between dilation and erosion.
