FastN2DToVec

Converts corners from two-dimensional image to an array of structures.

Syntax

IppStatus ippiFastN2DToVec_8u(const Ipp8u* pSrcCorner, int srcCornerStep, const Ipp8u* pSrcScore, int srcScoreStep, IppiCornerFastN* pDst, IppiSize srcRoiSize, int maxLen, int* pNumCorners, IppiFastNSpec* pSpec);

Parameters

pSrcCorner: Pointer to the source image with corners.
srcCornerStep: Distance, in bytes, between the starting points of consecutive lines in the source image with corners.
pSrcScore: Pointer to the source image with scores.
srcScoreStep: Distance, in bytes, between the starting points of consecutive lines in the source image with score.
pDst: Pointer to the destination vector of structures.
srcRoiSize: Size of the source ROI, in pixels.
maxLen: Length of the array of structures.
pNumCorners: Pointer to the number of corners in the source image.
pSpec: Pointer to the specification structure.

Description

This function converts two-dimensional image with corners to an array of structures. The result is stored in pDst.

For an example on how to use this function, refer to the example provided with the FastN function description.

Return Values

ippStsNoErr

Indicates no error. Any other value indicates an error.

ippStsNullPtrErr

Indicates an error when:

pSrcCorner, pDst, pNumCorners, or pSpec is NULL
pSrcScore is NULL if option is not equal to IPP_FASTN_SCORE_MODE0

ippStsSizeErr

Indicates an error when srcRoiSize is less than, or equal to zero.

ippContextMatchErr

Indicates an error when the specification structure does not match the operation.

ippDataTypeErr

Indicates an error when dataType has an illegal value.

ippNumChannelsErr

Indicates an error when numChannels has an illegal value.

ippOutOfRangeErr

Indicates an error when orientationBins or N has an illegal value.

ippBadArgsErr

Indicates an error when option or circleRadius has an illegal value.

ippThresholdErr

Indicates an error when threshold is negative.
