Class WaveletTransformInt<T extends GrayI<T>>

boofcv.abst.transform.wavelet.impl.WaveletTransformInt<T>

All Implemented Interfaces:

WaveletTransform<T,GrayS32,WlCoef_I32>

public class WaveletTransformInt<T extends GrayI<T>>
extends Object
implements WaveletTransform<T,GrayS32,WlCoef_I32>

Implementation of WaveletTransform for GrayI.

Wavelet transforms are only provided for 32-bit integer images, so if the input image is not 32-bit then it is first copied into a 32-bit image and then transformed. This is all done internally and is transparent to the user.

 int maxPixelValue,
 Class<T> inputType)

Method Details

transform

public GrayS32 transform(T original,
 @Nullable
 @Nullable GrayS32 transformed)

Description copied from interface: WaveletTransform

Computes the wavelet transform of the input image. If no output/transform image is provided a new image is created and returned.

Specified by:

transform in interface WaveletTransform<T extends GrayI<T>,GrayS32,WlCoef_I32>

Parameters:

original - Original unmodified image. Not modified.

transformed - Where the computed transform is stored. If null a new image is created. Modified.

Returns:

Wavelet transform.

invert

public void invert(GrayS32 transformed,
 T original)

Description copied from interface: WaveletTransform

Applies the inverse wavelet transform to the specified image.

Specified by:

invert in interface WaveletTransform<T extends GrayI<T>,GrayS32,WlCoef_I32>

Parameters:

transformed - Wavelet transform of the image. Not modified.

original - Reconstructed image from transform. Modified.

getLevels

public int getLevels()

Description copied from interface: WaveletTransform

Number of levels in the wavelet transform.

Specified by:

getLevels in interface WaveletTransform<T extends GrayI<T>,GrayS32,WlCoef_I32>

Returns:

number of levels.

getBorderType

public BorderType getBorderType()

Description copied from interface: WaveletTransform

Returns how the borders are handled.

Specified by:

getBorderType in interface WaveletTransform<T extends GrayI<T>,GrayS32,WlCoef_I32>

Returns:

Type of border used.

getDescription

public WaveletDescription<WlCoef_I32> getDescription()

Description copied from interface: WaveletTransform

Description of the wavelet.

Specified by:

getDescription in interface WaveletTransform<T extends GrayI<T>,GrayS32,WlCoef_I32>

Returns:

wavelet description.

getOriginalType

public Class<T> getOriginalType()

Specified by:

getOriginalType in interface WaveletTransform<T extends GrayI<T>,GrayS32,WlCoef_I32>
