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]imageImage to be down sampled.
Returns
Down-sampled image.
Exceptions
Anyexception 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]imageImage to be up sampled.
Returns
Up-sampled image.
Exceptions
Anyexception 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.
