Function Documentation

bool createDirectory

(

std::string &

path

)

Creates the directory given its path.

Parameters

path	The path string

Returns

true on success

double getRandomDouble	(	double	min,
		double	max
	)

Get a random double in a given interval.

Value is sampled from uniform distribution

Parameters

min	Interval lower bound
max	Interval upper bound

Returns

Random double

int getRandomInt	(	int	min,
		int	max
	)

Get a random integer in a given interval.

Value is sampled from uniform distribution

Parameters

min	Interval lower bound
max	Interval upper bound

Returns

Random integer

const std::string getUsage

(

const char *

argv_0

)

Returns string with program usage information.

Returns

Program usage

void parseArgs	(	int	argc,
		char **	argv,
		unsigned int &	scenes,
		unsigned int &	start,
		std::string &	imgs_dir,
		std::string &	dataset_dir
	)

Parses command-line arguments.

Parameters

argc	Argument count
argv	Argument values
scenes	Number of scenes to generate
start	Index of the first scene
imgs_dir	Image output directory
dataset_dir	Dataset annotations output directory

void shuffleIntVector

(

std::vector< int > &

vector

)

Randomly shuffles an integer vector.
