Class PyramidFloat<T extends ImageGray>

java.lang.Object

boofcv.struct.pyramid.ImagePyramidBase<T>

boofcv.struct.pyramid.PyramidFloat<T>

All Implemented Interfaces:

ImagePyramid<T>

Direct Known Subclasses:

PyramidFloatGaussianScale, PyramidFloatScale

public abstract class PyramidFloat<T extends ImageGray>
extends ImagePyramidBase<T>

An image pyramid where each level can be an arbitrary scale. Higher levels in the pyramid are sub-sampled from lower levels in the pyramid allowing fractions of a pixel change. This added flexibility comes at the cost of some performance relative to PyramidDiscrete.

An ImagePyramid where the scale factor between each level is specified using a floating point number.

PyramidFloat

public PyramidFloat(java.lang.Class<T> imageType,
                    double... scaleFactors)

Defines the image pyramid.

Parameters:

imageType - Type of image

scaleFactors - (optional) Specifies the scale of each layer in the pyramid. See restrictions on scaleFactor in setScaleFactors(double...).

Method Detail

setScaleFactors

public void setScaleFactors(double... scaleFactors)

Specifies the pyramid's structure.

Parameters:

scaleFactors - Change in scale factor for each layer in the pyramid.

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.
