Functions

func NearestObject

func NearestObject(objects Objects) int

NearestObject returns an index of the nearest Object in the selection.

Types

type Color

type Color struct {
	// contains filtered or unexported fields
}

Color stores RGB color values and a thickness value.

func NewColor

func NewColor(r, g, b, t int) *Color

NewColor constructs a new Color.

func (*Color) T

func (c *Color) T() int

T returns thickness of the color line.

func (*Color) ToRGBA

func (c *Color) ToRGBA() color.RGBA

ToRGBA returns Color in color.RGBA.

type Object

type Object struct {
	// contains filtered or unexported fields
}

Object is detectable by the observer.

func FromRect

func FromRect(rect image.Rectangle) *Object

FromRect constructs an Object from a rectangle.

func (*Object) Center

func (o *Object) Center() image.Point

Center calculates a center point of the Object.

func (*Object) Draw

func (o *Object) Draw(img *gocv.Mat, c color.RGBA, thickness int)

Draw draws an Object on the image matrices.

type Objects

type Objects []*Object

Objects represents multiple Objects.

func FromRects

func FromRects(rects []image.Rectangle) Objects

FromRects constructs a slice of Objects from the given slice of rectangles.

func (Objects) Draw

func (oo Objects) Draw(img *gocv.Mat, c color.RGBA, thickness int)

Draw draws Objects on the image matrices.
