Erosion(morphological operator) for images.
The erosion function is a morphological transformation on an image that requires two inputs. The first is the image to be morphed, and the second is the mask indicating neighborhood that must be white in order to preserve each pixel.
In erode, for each pixel, the mask is centered at the pixel. If each pixel of the mask matches the corresponding pixel on the image, then no change is made. If there is at least one mismatch, then pixels are changed to the background color (black).
For further reference, see: Erosion (morphology)
Sample input and output are shown below:
C Interface for image erosion (min filter)
|[out]||out||array is the eroded image|
|[in]||in||array is the input image|
|[in]||mask||is the neighborhood window|
maskis all ones, this function behaves like min filter
