Data Structures

Here are the data structures with brief descriptions:

[detail level 12]

CycleTimer	This uses the cycle counter of the processor
filesystem	Provides useful wrappers around many filesystem related functionality, including reading writing certain common data structures as well as common operations (ex
cvmat_header
misc
numerics	Provides useful wrappers around many numerical functionality, such as dealing with sparse and dense matrix / vector data
vision	Provides useful wrappers around many OpenCV functions as well as some simple vision - based routines
SIFTParams	Describes SIFT extraction parameters when calling OpenCV's SIFT implementation
BagOfWords	Implements a Bag of Words based (BoW) image search
MatchResults	Subclass of match results base which also returns scores
SearchParams	Subclass of train params base which specifies inverted index training parameters
TrainParams	Subclass of train params base which specifies inverted index training parameters
cvmat_header
Dataset	Abstract wrapper describing a dataset
Image	Abstract class representing an image
InvertedIndex	Implements a Bag of Words based (BoW) image search using an inverted index
MatchResults	Subclass of match results base which also returns scores
SearchParams	Subclass of train params base which specifies inverted index training parameters
TrainParams	Subclass of train params base which specifies inverted index training parameters
MatchesPage	MatchesPage class keeps track of query images and their matches, and outputs an html page containing these matches for visualization purposes
MatchResultsBase	Structure to hold returned match results (returned from a search call)
SearchBase	Abstract class from which all search structures and methods derive from
SearchParamsBase	Structure to hold input search parameters (ex. #matches, threshold, number neighbors to consider, etc.)
SimpleDataset	SimpleDataset is a sample implementation of a Dataset, where the data is stored as JPEG images in a single folder called images/ and features are stored in a folder feats/<feat_name>
SimpleImage	SimpleImage class used with the SimpleDataset class
TrainParamsBase	Structure to hold input training parameters (ex. #clusters, #examples to consider)
VocabTree
MatchResults	Subclass of match results base which also returns scores
SearchParams	Subclass of train params base which specifies Vocab Tree training parameters
TrainParams	Subclass of train params base which specifies vocab tree training parameters
