Function Documentation

GaussianPyramidDown()

std::unique_ptr< Image > GaussianPyramidDown ( const Image &  image )

inline

This function down samples an image in the sense of a Gaussian pyramid.

Parameters

[in]

image

Image to be down sampled.

Returns

Down-sampled image.

Exceptions

Any	exception derived from std::exception including CvbException.

It applies a Gaussian Cvb::Foundation::FixedFilterSize::Kernel5x5 to the image, then down samples the image by omitting every odd row and column, producing an output image whose size is halved in each dimension.

GaussianPyramidUp()

std::unique_ptr< Image > GaussianPyramidUp ( const Image &  image )

inline

This function up samples an image in the sense of a Gaussian pyramid.

Parameters

[in]

image

Image to be up sampled.

Returns

Up-sampled image.

Exceptions

Any	exception derived from std::exception including CvbException.

It inserts odd columns and rows filled with 0, then applies a Gaussian Cvb::Foundation::FixedFilterSize::Kernel5x5 multiplied by 4 to the image.
