                                                    java.awt.image.BufferedImage dst)

colorizeSign

public static java.awt.image.BufferedImage colorizeSign(boofcv.struct.image.ImageGray src,

                                                        double normalize)

Renders a colored image where the color indicates the sign and intensity its magnitude. The input is divided by normalize to render it in the appropriate scale.

Parameters:

src - Input single band image.

dst - Where the image is rendered into. If null a new BufferedImage will be created and return.

normalize - Used to normalize the input image. If ≤ 0 then the max value will be used

Returns:

Rendered image.

grayUnsigned

public static java.awt.image.BufferedImage grayUnsigned(boofcv.struct.image.GrayI src,
                                                        java.awt.image.BufferedImage dst,

                                                         double normalize)

Renders a gray scale image of the input image's intensity.

dst(i,j) = 255*abs(src(i,j))/normalize

Parameters:

src - Input single band image.

dst - Where the image is rendered into. If null a new BufferedImage will be created and return.

normalize - Used to normalize the input image. If < 0 then this value is automatically computed.

Returns:

Rendered image.
