Package boofcv.struct.pyramid

Class PyramidDiscrete<T extends ImageBase<T>>

java.lang.Object

boofcv.struct.pyramid.ImagePyramidBase<T>

boofcv.struct.pyramid.PyramidDiscrete<T>

All Implemented Interfaces:

ImagePyramid<T>

Direct Known Subclasses:

PyramidDiscreteAverage, PyramidDiscreteSampleBlur

public abstract class PyramidDiscrete<T extends ImageBase<T>>
extends ImagePyramidBase<T>

In this implementation the scale factor between each layer is limited to being a positive integer that is evenly divisible by the previous layer. This added constraint allows further optimization to be performed.

PyramidDiscrete

protected PyramidDiscrete(ImageType<T> imageType,
 boolean saveOriginalReference,
 @Nullable
 @Nullable ConfigDiscreteLevels configLayers)

Specifies input image size and behavior of top most layer.

Parameters:

imageType - Type of image.

saveOriginalReference - If a reference to the full resolution image should be saved instead of copied. Set to false if you don't know what you are doing.

configLayers - Specifies how the levels are computed

PyramidDiscrete

protected PyramidDiscrete(PyramidDiscrete<T> orig)

Method Details

initialize

public void initialize(int width,
 int height)

Description copied from class: ImagePyramidBase

Initializes internal data structures based on the input image's size. Should be called each time a new image is processed.

Specified by:

initialize in interface ImagePyramid<T extends ImageBase<T>>

Overrides:

initialize in class ImagePyramidBase<T extends ImageBase<T>>

Parameters:

width - Image width

height - Image height

computeScales

protected void computeScales(int width,
 int height)

getScales

public int[] getScales()

getScale

public double getScale(int layer)

Description copied from interface: ImagePyramid

Returns the scale of the specified layer in the pyramid. Larger the scale smaller the image is relative to the input image.

Parameters:

layer - Which layer is being inspected.

Returns:

The layer's scale.

getNumLayers

public int getNumLayers()

Description copied from interface: ImagePyramid

Returns the number of layers in the pyramid.
