Detailed Description

Google Test Unit Tests for the Box Filtering kernels.

Note

Use the --profiling flag to enable profiling of the kernels.

The benchmarks in these tests are against naive CPU implementations of the associated algorithms. They are used only for testing purposes, and not for examining the performance of their GPU alternatives.

Function Documentation

int main	(	int	argc,
		char **	argv
	)

TEST	(	BoxFilter	,
		scan
	)

Tests the scan kernel.

The operation is a scan on the rows of an array.

TEST	(	BoxFilter	,
		transpose
	)

Tests the transpose kernel.

The operation is a matrix transposition.

TEST	(	BoxFilter	,
		sat
	)

Tests the construction of a Summed Area Table (SAT).

The operations performed are a scan on the rows of an array, an array transposition, and then a scan on the columns of the array.

TEST	(	BoxFilter	,
		boxFilterSAT
	)

Tests the boxFilterSAT kernel.

The operation is a blurring effect (mean filtering) on an image, using SAT arrays.

TEST	(	BoxFilter	,
		boxFilter
	)

Tests the boxFilter kernel.

The operation is a blurring effect (mean filtering) on an image.
