Detailed Description

The class defining termination criteria for iterative algorithms.

You can initialize it by default constructor and then override any parameters, or the structure may be fully initialized using the advanced variant of the constructor.

Examples:
samples/cpp/camshiftdemo.cpp, samples/cpp/image_alignment.cpp, samples/cpp/kmeans.cpp, samples/cpp/lkdemo.cpp, and samples/cpp/train_HOG.cpp.

Member Enumeration Documentation

◆ Type

Criteria type, can be one of: COUNT, EPS or COUNT + EPS

Enumerator
COUNT 

the maximum number of iterations or elements to compute

MAX_ITER 

ditto

EPS 

the desired accuracy or change in parameters at which the iterative algorithm stops

Constructor & Destructor Documentation

◆ TermCriteria() [1/2]

cv::TermCriteria::TermCriteria ( )

default constructor

◆ TermCriteria() [2/2]

cv::TermCriteria::TermCriteria ( int  type,
int  maxCount,
double  epsilon 
)
Parameters
typeThe type of termination criteria, one of TermCriteria::Type
maxCountThe maximum number of iterations or elements to compute.
epsilonThe desired accuracy or change in parameters at which the iterative algorithm stops.
