typedef struct cx::VNNclAlgorithm::__frameBlock_t cx::VNNclAlgorithm::frameBlock_t

A representation of a Frame block in CPU memory. Since OpenCL has an upper limit on how big memory objects can be, we need to partition the input US images into several blocks. This struct represents one such block

	)

virtual

Build the OpenCL kernel

Parameters

program_src	The kernel source code
kernelPath	path to kernel source
nMaxPlanes	The MAX_PLANES parameter of the kernel, i.e. max value of how many planes to include in the reconstruction of one voxel
nPlanes	Number of image planes in the input data set
method	The method ID. See kernels.cl for more information
planeMethod	the plane method ID. See kernels.cl for more information
nStarts	number of starts for multistart search for close planes
brightnessWeight	The extra weight to give pixels brighter than mean
newnessWeight	The extra weight to give pixels newer than mean

Returns: True on suc

void cx::VNNclAlgorithm::fillPlaneMatrices	(	float *	planeMatrices,
		ProcessedUSInputDataPtr	input
	)

virtual

Fill the supplied array of floats with the values from the transformation matrices in input. The data is stored like this: [ a b c d e f g h -> [ a b c d e f g h i j k l m n o p ] i j k l m n o p ] I.e: 16 floats per image plane, row major.

Parameters

planeMatrices	Pointer to array of 16*number of image planes floats where the matrices will be stored
input	The US data - which also has position data

void cx::VNNclAlgorithm::freeFrameBlocks	(	frameBlock_t *	framePointers,
		int	numBlocks
	)

virtual

Free a set of frame blocks allocated by initializeFrameBlocks Does not free the actual frameBlock_t structure, but the data pointer is free'd. You still have to free the frameBlocks!

Parameters

framePointers	Pointer to first element in array of frame blocks
numBlocks	number of blocks in the array

		int	nMaxPlanes,
		int	nPlanes,
		int	method,

		int	nStarts,
		float	brightnessWeight,
		float	newnessWeight
	)

virtual

Initialize OpenCL. This function initializes OpenCL and builds the kernel with the given parameters. Note that these parameters are set at compile time and not kernel run time. Uses buildCLProgram() to build the kernel.

Parameters

kernelFile	Path to the OpenCL kernel source
nMaxPlanes	The MAX_PLANES parameter of the kernel, i.e. max value of how many planes to include in the reconstruction of one voxel
nPlanes	Number of image planes in the input data set
method	The method ID. See kernels.cl for more information
planeMethod	the plane method ID. See kernels.cl for more information
nStarts	number of starts for multistart search for close planes
brightnessWeight	The extra weight to give pixels brighter than mean
newnessWeight	The extra weight to give pixels newer than mean

Returns: True on success

bool cx::VNNclAlgorithm::initializeFrameBlocks	(	frameBlock_t *	framePointers,
		int	numBlocks,
		ProcessedUSInputDataPtr	inputFrames
	)

virtual

Split the US input into numBlock blocks of whole frames and store them in framePointers.

Parameters

[out]	framePointers	Pre-allocated array of numBlocks unsigned char* pointers Data will be returned here
[in]	numBlocks	Number of blocks to split US input into
[in]	inputFrames	The input US B-scans

Returns: true on success, false otherwise

bool cx::VNNclAlgorithm::reconstruct	(	ProcessedUSInputDataPtr	input,
		vtkImageDataPtr	outputData,
		float	radius,
		int	nClosePlanes
	)

virtual

Perform GPU Reconstruction. This function initializes the CL memory objects, calls the kernel and reads back the result, which is stored in outputData.

Parameters

input	The input US data
outputData	The output volume is stored here
radius	The radius of the kernel - i.e. how far away to look for image planes to use
nClosePlanes	The number of close planes to search for

Returns: true on success

void cx::VNNclAlgorithm::setProfiling ( bool on )

Enable/diable OpenCL profiling for this algorithm
