Class InterpolatePixel_S_to_MB_MultiSpectral<T extends ImageSingleBand>

java.lang.Object

boofcv.abst.filter.interpolate.InterpolatePixel_S_to_MB_MultiSpectral<T>

All Implemented Interfaces:

InterpolatePixel<MultiSpectral<T>>, InterpolatePixelMB<MultiSpectral<T>>

public class InterpolatePixel_S_to_MB_MultiSpectral<T extends ImageSingleBand>
extends Object
implements InterpolatePixelMB<MultiSpectral<T>>

Wrapper around InterpolatePixelS which allows it to interpolate MultiSpectral inside a InterpolatePixelMB. Performs the same calculations multiple times compared to a custom solution.

int	getFastBorderX() Border around the image that fast interpolation cannot be called.
int	getFastBorderY() Border around the image that fast interpolation cannot be called.
MultiSpectral<T>	getImage() Returns the image which is being interpolated.
boolean	isInFastBounds(float x, float y) Is the requested pixel inside the image boundary for which fast unsafe interpolation can be performed.

Method Detail

get

public void get(float x,
       float y,
       float[] values)

Description copied from interface: InterpolatePixelMB

Returns the interpolated pixel values at the specified location while taking in account the image border. Bounds checking is done to ensure that the coordinate is inside the image and to see if the interpolation technique needs to be adjusted for the image border.

Specified by:

get in interface InterpolatePixelMB<MultiSpectral<T extends ImageSingleBand>>

Parameters:

x - Point's x-coordinate. x >= 0 && x < image.width

y - Point's y-coordinate. y >= 0 && y < image.height

values - Interpolated value across all bands.

get_fast

public void get_fast(float x,
            float y,
            float[] values)

Description copied from interface: InterpolatePixelMB

Returns the interpolated pixel values 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 InterpolatePixelMB<MultiSpectral<T extends ImageSingleBand>>

Parameters:

x - Point's x-coordinate.

y - Point's y-coordinate.

values - Interpolated value across all bands.

setImage

public void setImage(MultiSpectral<T> image)

Description copied from interface: InterpolatePixel

Change the image that is being interpolated.

Specified by:

setImage in interface InterpolatePixel<MultiSpectral<T extends ImageSingleBand>>

Parameters:

image - An image.

getImage

public MultiSpectral<T> getImage()

Description copied from interface: InterpolatePixel

Returns the image which is being interpolated.

Specified by:

getImage in interface InterpolatePixel<MultiSpectral<T extends ImageSingleBand>>

Returns:

A reference to the image being interpolated.

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<MultiSpectral<T extends ImageSingleBand>>

Parameters:

x - Point's x-coordinate.

y - Point's y-coordinate.

Returns:

true if get_unsafe() can be called.

getFastBorderX

public int getFastBorderX()

Description copied from interface: InterpolatePixel

Border around the image that fast interpolation cannot be called.

Specified by:

getFastBorderX in interface InterpolatePixel<MultiSpectral<T extends ImageSingleBand>>

Returns:

Border size in pixels

getFastBorderY

public int getFastBorderY()

Description copied from interface: InterpolatePixel

Border around the image that fast interpolation cannot be called.

Specified by:

getFastBorderY in interface InterpolatePixel<MultiSpectral<T extends ImageSingleBand>>

Returns:

Border size in pixels
