Detailed Description

An application examining the potential of the Random Ball Cover data structure for image segmentation.

This application was developed for testing the eligibility of RBC for image segmentation. Try changing the nr variable for configuring the number of representatives, and/or the a variable for adjusting the influence of the color intensity, and examine the effects on the image. By creating a graph with the representatives, and adjusting the edge weights, connected components could be created that would define areas of interest.

Note

The result is randomized. To assign representatives at regular intervals, try uncommenting the commented sections, and comment out the relevant lines (marked with // at the end).

Function Documentation

int main	(	int	argc,
		const char **	argv
	)

template<typename iterator >

void random_unique	(	iterator	xBegin,
		iterator	xEnd,
		iterator	rBegin,
		iterator	rEnd
	)

Picks a number of elements uniformly at random without replacement from the input sequence.

The function implements a Fisher-Yates shuffle.

Parameters

[in]	xBegin	iterator to the initial position of the input sequence.
[in]	xEnd	iterator past the final position of the input sequence.
[out]	rBegin	iterator to the initial position of the output sequence.
[out]	rEnd	iterator past the final position of the output sequence.

Variable Documentation

const std::vector<std::string> kernel_files

Initial value:

= { "kernels/rbc_kernels.cl", 
                                                "kernels/scan_kernels.cl" }
