Class ImplInterpolatePixelConvolution_U8

java.lang.Object

boofcv.alg.interpolate.impl.ImplInterpolatePixelConvolution_U8

All Implemented Interfaces:

InterpolatePixel<ImageUInt8>, InterpolatePixelS<ImageUInt8>

public class ImplInterpolatePixelConvolution_U8
extends Object
implements InterpolatePixelS<ImageUInt8>

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,
                                  float max)

Method Detail

setImage

public void setImage(ImageUInt8 image)

Description copied from interface: InterpolatePixel

Change the image that is being interpolated.

Specified by:

setImage in interface InterpolatePixel<ImageUInt8>

Parameters:

image - An image.

getImage

public ImageUInt8 getImage()

Description copied from interface: InterpolatePixel

Returns the image which is being interpolated.

Specified by:

getImage in interface InterpolatePixel<ImageUInt8>

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 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 InterpolatePixelS<ImageUInt8>

Parameters:

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

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

Returns:

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

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<ImageUInt8>

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<ImageUInt8>

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<ImageUInt8>

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<ImageUInt8>

Returns:

Border size in pixels
