ASW_Disparity()

__kernel void ASW_Disparity	(	__global uchar *	left,
		__global uchar *	right,
		__global float *	datacost,
		int	width,
		int	height,
		int	dispRange,
		int	mSize
	)

Compute stereo datacost using a window of Adaptive Support Weight (ASW)

Parameters

left	Left input image
right	Right input image
datacost	The initial 3D cost
width	The image width
height	The image height
dispRange	The stereo disparity search range
mSize	The local window size

ASW_Disparity_image()

__kernel void ASW_Disparity_image	(	const int	with_gaussian,
		__read_only image2d_t	left,
		__read_only image2d_t	right,
		__global float *	datacost,
		int	dispRange,
		int	mSize
	)

Compute stereo datacost using a window of Adaptive Support Weight (ASW)
using image2d

Parameters

with_gaussian	whether to process Gaussian or not; true = 1, false = 0
left	Left input image; with gaussian : float4 image2d, without gaussian : uint4 image2d
right	Right input image; with gaussian : float4 image2d, without gaussian : uint4 image2d
datacost	The initial 3D cost
dispRange	The stereo disparity search range
mSize	The local window size
