Class ImplInterpolatePixelConvolution_U8

java.lang.Object

boofcv.alg.interpolate.impl.ImplInterpolatePixelConvolution_U8

All Implemented Interfaces:

InterpolatePixel<GrayU8>, InterpolatePixelS<GrayU8>

public class ImplInterpolatePixelConvolution_U8
extends java.lang.Object
implements InterpolatePixelS<GrayU8>

Performs interpolation by convolving a continuous-discrete function across the image. Borders are handled by re-normalizing. It is assumed that the kernel will sum up to one. This is particularly important for the unsafe_get() function which does not re-normalize.

ImplInterpolatePixelConvolution_U8

public ImplInterpolatePixelConvolution_U8(KernelContinuous1D_F32 kernel,
                                          float min,

Method Detail

setBorder

public void setBorder(ImageBorder<GrayU8> border)

Description copied from interface: InterpolatePixel

Set's the class used to "read" pixels outside the image border.

Specified by:

setBorder in interface InterpolatePixel<GrayU8>

Parameters:

border - Class for reading outside the image border

setImage

public void setImage(GrayU8 image)

Description copied from interface: InterpolatePixel

Change the image that is being interpolated.

Specified by:

setImage in interface InterpolatePixel<GrayU8>

Parameters:

image - An image.

getImage

public GrayU8 getImage()

Description copied from interface: InterpolatePixel

Returns the image which is being interpolated.

Specified by:

getImage in interface InterpolatePixel<GrayU8>

Returns:

A reference to the image being interpolated.

get

public float get(float x,
                 float y)

Description copied from interface: InterpolatePixelS

Returns the interpolated pixel value at the specified location while checking to see if border conditions apply. If the requested pixel is outside the image border it will attempt to process it using or throw a null pointer exception of a border handler has not been specified.

Specified by:

get in interface InterpolatePixelS<GrayU8>

Parameters:

x - Point's x-coordinate. x ≥ 0 && x < image.width or all values if border specified

y - Point's y-coordinate. y ≥ 0 && y < image.height or all values if border specified

Returns:

Interpolated intensity value or NaN if it can't be interpolated.

get_border

public float get_border(float x,
                        float y)

get_fast

public float get_fast(float x,
                      float y)

Description copied from interface: InterpolatePixelS

Returns the interpolated pixel value at the specified location while assuming it is inside the image far away from the border. For any input point InterpolatePixel.isInFastBounds(float, float) should return true.

Specified by:

get_fast in interface InterpolatePixelS<GrayU8>

Parameters:

x - Point's x-coordinate.

y - Point's y-coordinate.

Returns:

Interpolated intensity value.

isInFastBounds

public boolean isInFastBounds(float x,
                              float y)

Description copied from interface: InterpolatePixel

Is the requested pixel inside the image boundary for which fast unsafe interpolation can be performed.

Specified by:

isInFastBounds in interface InterpolatePixel<GrayU8>

Parameters:

x - Point's x-coordinate.

y - Point's y-coordinate.

Returns:

true if get_unsafe() can be called.

Specified by:

getFastBorderX in interface InterpolatePixel<GrayU8>

Returns:

Description copied from interface: InterpolatePixel

Returns the class which handles the image border

Specified by:

getBorder in interface InterpolatePixel<GrayU8>

getImageType

public ImageType<GrayU8> getImageType()

Description copied from interface: InterpolatePixel

Type of image it can process

Specified by:

getImageType in interface InterpolatePixel<GrayU8>
