Detailed Description

The Regions class describe a set of regions extracted from an image. It contains both a feature (position, scale, orientation) and a descriptor (photometric neighborhood description).

Describe an image a set of regions (position, ...) + attributes Each region is described by a set of attributes (descriptor)

Member Function Documentation

blindDescriptors()

virtual const void* aliceVision::feature::Regions::blindDescriptors ( ) const

pure virtual

Return a blind pointer to the container of the descriptors array.

Note

: Descriptors are always stored as an std::vector<DescType>.

Implemented in aliceVision::feature::FeatDescRegions< T, L, regionType >.

DescriptorRawData()

virtual const void* aliceVision::feature::Regions::DescriptorRawData ( ) const

pure virtual

Return a pointer to the first value of the descriptor array.

Note

: Descriptors are always stored as a flat array of descriptors.

Implemented in aliceVision::feature::FeatDescRegions< T, L, regionType >.
