Functions

func GenerateSubBounds

func GenerateSubBounds(in *matrix.M, offset int) []image.Rectangle

GenerateSubBounds based on an input matrix. Useful to run algorithms in parallel, each focusing on a sub-bound.

func LoadImage

func LoadImage(fname string) (image.Image, *matrix.M)

LoadImage opens a file and attempts to decode the image If the dimensions of the image are bigger than expected, then the image is resized to fit the expected resolution.

func RunInParallel

func RunInParallel(in *matrix.M, offset int, fn func(wg *sync.WaitGroup, bounds image.Rectangle))
