FilterUnsharpBorder(NPPImage_16uC1, Single, Single, Single, Single, NppiBorderType, CudaDeviceVariable<Byte>)

Filters the image using a unsharp-mask sharpening filter kernel with border control.

The algorithm involves the following steps:

Smooth the original image with a Gaussian filter, with the width controlled by the nRadius.

Subtract the smoothed image from the original to create a high-pass filtered image.

Apply any clipping needed on the high-pass image, as controlled by the nThreshold.

Add a certain percentage of the high-pass filtered image to the original image, with the percentage controlled by the nWeight. In pseudocode this algorithm can be written as:

HighPass = Image - Gaussian(Image)

Result = Image + nWeight * HighPass * ( |HighPass| >= nThreshold )

where nWeight is the amount, nThreshold is the threshold, and >= indicates a Boolean operation, 1 if true, or 0 otherwise.

If any portion of the mask overlaps the source image boundary, the requested border type operation is applied to all mask pixels which fall outside of the source image.

WarpAffine(NPPImage_16uC1, Double[,], InterpolationMode)

Affine transform of an image.

This function operates using given transform coefficients that can be obtained by using nppiGetAffineTransform function or set explicitly. The function operates on source and destination regions of interest. The affine warp function transforms the source image pixel coordinates (x,y) according to the following formulas:

X_new = C_00 * x + C_01 * y + C_02

Y_new = C_10 * x + C_11 * y + C_12

The transformed part of the source image is resampled using the specified interpolation method and written to the destination ROI. The functions nppiGetAffineQuad and nppiGetAffineBound can help with destination ROI specification.

NPPI specific recommendation:

The function operates using 2 types of kernels: fast and accurate. The fast method is about 4 times faster than its accurate variant, but does not perform memory access checks and requires the destination ROI to be 64 bytes aligned. Hence any destination ROI is chunked into 3 vertical stripes: the first and the third are processed by accurate kernels and the central one is processed by the fast one.

In order to get the maximum available speed of execution, the projection of destination ROI onto image addresses must be 64 bytes aligned. This is always true if the values

(int)((void *)(pDst + dstRoi.x))

and

(int)((void *)(pDst + dstRoi.x + dstRoi.width))

are multiples of 64. Another rule of thumb is to specify destination ROI in such way that left and right sides of the projected image are separated from the ROI by at least 63 bytes from each side. However, this requires the whole ROI to be part of allocated memory. In case when the conditions above are not satisfied, the function may decrease in speed slightly and will return NPP_MISALIGNED_DST_ROI_WARNING warning.

Declaration

public void WarpAffine(NPPImage_16uC1 dest, double[, ] coeffs, InterpolationMode eInterpolation)

Parameters

Type	Name	Description
NPPImage_16uC1	dest	Destination image
System.Double[,]	coeffs	Affine transform coefficients [2,3]
InterpolationMode	eInterpolation	Interpolation mode: can be NearestNeighbor, Linear or Cubic

WarpAffineBack(NPPImage_16uC1, Double[,], InterpolationMode)

Inverse affine transform of an image.

This function operates using given transform coefficients that can be obtained by using nppiGetAffineTransform function or set explicitly. Thus there is no need to invert coefficients in your application before calling WarpAffineBack. The function operates on source and destination regions of interest.

The affine warp function transforms the source image pixel coordinates (x,y) according to the following formulas:

X_new = C_00 * x + C_01 * y + C_02

WarpAffineQuad(Double[,], NPPImage_16uC1, Double[,], InterpolationMode)

The function nppiWarpAffineQuad uses the same formulas for pixel mapping as in nppiWarpAffine function. The transform coefficients are computed internally. The transformed part of the source image is resampled using the specified eInterpolation method and written to the destination ROI.

WarpPerspective(NPPImage_16uC1, Double[,], InterpolationMode)

Perspective transform of an image.

This function operates using given transform coefficients that can be obtained by using nppiGetPerspectiveTransform function or set explicitly. The function operates on source and destination regions of interest. The perspective warp function transforms the source image pixel coordinates (x,y) according to the following formulas:

X_new = (C_00 * x + C_01 * y + C_02) / (C_20 * x + C_21 * y + C_22)

Y_new = (C_10 * x + C_11 * y + C_12) / (C_20 * x + C_21 * y + C_22)

are multiples of 64. Another rule of thumb is to specify destination ROI in such way that left and right sides of the projected image are separated from the ROI by at least 63 bytes from each side. However, this requires the whole ROI to be part of allocated memory. In case when the conditions above are not satisfied, the function may decrease in speed slightly and will return NPP_MISALIGNED_DST_ROI_WARNING warning.
