public interface DescribeImageDense<T extends boofcv.struct.image.ImageBase,Desc extends TupleDesc>
extends DescriptorInfo<Desc>

Computes feature descriptors across the whole image. No feature detection is performed. Descriptions are typically computed at regular intervals. Scale, orientation, and other local geometric information is typically not computed or returned to the user.

Method Summary

Modifier and Type	Method and Description
void	configure(double descriptorScale, double periodX, double periodY) Configures how features are sampled across the image.
java.util.List<Desc>	getDescriptions() Returns a list of the computed descriptions.
boofcv.struct.image.ImageType<T>	getImageType() Description of the type of image it can process
java.util.List<georegression.struct.point.Point2D_I32>	getLocations() Returns a list of locations that the descriptors are computed at
void	process(T input) Processes the image and computes the dense image features.

Method Detail

configure

void configure(double descriptorScale,
               double periodX,
               double periodY)

Configures how features are sampled across the image.

NOTE: The specific implementation is allowed to tweak these numbers. The period might be adjusted to ensure an even sampling across the entire image is done.

Parameters:

descriptorScale - Scales the size of the region the descriptor is computed up or down, e.g. 2 = twice as large. Try 1.0

periodX - Pixels between samples along x-axis

periodY - Pixels between samples along y-axis

process

void process(T input)

Processes the image and computes the dense image features.

Parameters:

input - Input image.

getDescriptions

java.util.List<Desc> getDescriptions()

Returns a list of the computed descriptions.

The list and everything contained inside of it are owned by this class and subject to modification the next time process(ImageBase) is called.

Returns:

list of descriptions

getLocations

java.util.List<georegression.struct.point.Point2D_I32> getLocations()

Returns a list of locations that the descriptors are computed at

The list and everything contained inside of it are owned by this class and subject to modification the next time process(ImageBase) is called.

Returns:

list of descriptions

getImageType

boofcv.struct.image.ImageType<T> getImageType()

Description of the type of image it can process

Returns:

ImageDataType
