Functions

func DetectCorners

func DetectCorners(src *image.Gray) []image.Point

DetectCorners gives you a list of points containing corner of the image src src needs to be a grayscale image

func InPlaceRotation90

func InPlaceRotation90(src image.Image) image.Image

InPlaceRotation90 returns an image that references src and that will output you a 90 degrees rotation of src.

func Min

func Min(a, b int) int

Min between a and b

func SquareDistance

func SquareDistance(one, two image.Point) int

SquareDistance gives you distance^2 between two image.Point you'd have to Srqt it for it to be the correct distance.

Types
