## Detailed Description

This structure contains all the parameters that can be varied during the course of sampling algorithm. Below is the structure exposed, together with its members briefly explained with reference to the above discussion on algorithm's working.

## Constructor & Destructor Documentation

## ◆ Params()

cv::TrackerSamplerPF::Params::Params | ( |  | ) |

## Member Data Documentation

## ◆ alpha

double cv::TrackerSamplerPF::Params::alpha

with each new round we exponentially decrease the amount of "perturbing" we allow (like in simulated annealing) and this very alpha controls how fast annealing happens, ie. how fast perturbing decreases

## ◆ iterationNum

int cv::TrackerSamplerPF::Params::iterationNum

number of selection rounds

## ◆ particlesNum

int cv::TrackerSamplerPF::Params::particlesNum

number of "perturbed" boxes on each round

## ◆ std

Mat_<double> cv::TrackerSamplerPF::Params::std

initial values for perturbing (1-by-4 array, as each rectangle is given by 4 values – coordinates of opposite vertices, hence we have 4 values to perturb)
