Methods

dispose() → void
fill(Mat mat, int distType, double a, double b, {bool saturateRange = false, bool inplace = false}) → Mat
Fills arrays with random numbers. https://docs.opencv.org/4.x/d1/dd6/classcv_1_1RNG.html#ad26f2b09d9868cf108e84c9814aa682d
gaussian(double sigma, {int? maxCount}) → Stream<double>
The method transforms the state using the MWC algorithm and returns the next random number from the Gaussian distribution N(0,sigma) . That is, the mean value of the returned random numbers is zero and the standard deviation is the specified sigma . https://docs.opencv.org/4.x/d1/dd6/classcv_1_1RNG.html#a8df8ce4dc7d15916cee743e5a884639d
next({int? maxCount}) → Stream<int>
The method updates the state using the MWC algorithm and returns the next 32-bit random number. https://docs.opencv.org/4.x/d1/dd6/classcv_1_1RNG.html#ad8d035897a5e31e7fc3e1e6c378c32f5
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
inherited
uniform(num a, num b, {int? maxCount}) → Stream<num>
returns uniformly distributed integer random number from [a,b) range The methods transform the state using the MWC algorithm and return the next uniformly-distributed random number of the specified type, deduced from the input parameter type, from the range [a, b) . https://docs.opencv.org/4.x/d1/dd6/classcv_1_1RNG.html#a8325cc562269b47bcac2343639b6fafc

Operators
