func BinaryErosionDilationStructuringElement(size int) [][]float32

* Generates a structuring element for use in binary morphological operations * (It's just a load of 1s in a matrix of a given size)

func Gaussian(size int, sigma float32) [][]float32

* Generates a Gaussian kernel of a given size and standard deviation

func NormaliseKernel(kernel [][]float32) [][]float32

* Nornalises a kernel by ensuring that all of its elements sum to 1
