Types

type FastBilateral

type FastBilateral struct {
	Image      image.Image
	SigmaRange float64
	SigmaSpace float64
	// contains filtered or unexported fields
}

A FastBilateral filter is a non-linear, edge-preserving and noise-reducing smoothing filter for images. The intensity value at each pixel in an image is replaced by a weighted average of intensity values from nearby pixels.

func Auto

func Auto(m image.Image) *FastBilateral

Auto instanciates a new FastBilateral with automatic sigma values.

func New

func New(m image.Image, sigmaSpace, sigmaRange float64) *FastBilateral

New instanciates a new FastBilateral.

func (*FastBilateral) At

func (f *FastBilateral) At(x, y int) color.Color

At computes the interpolation and returns the filtered color at the given coordinates.

func (*FastBilateral) Bounds

func (f *FastBilateral) Bounds() image.Rectangle

Bounds implements image.Image interface.

func (*FastBilateral) ColorModel

func (f *FastBilateral) ColorModel() color.Model

ColorModel returns the Image's color model.

func (*FastBilateral) Execute

func (f *FastBilateral) Execute()

Execute runs the bilateral filter.

func (*FastBilateral) ResultImage

func (f *FastBilateral) ResultImage() image.Image

ResultImage computes the interpolation and returns the filtered image.
