FwStatus | fwiAbsDiffC_8u_C1R | ( | const Fw8u * pSrc, int srcStep, Fw8u * pDst, int dstStep, FwiSize roiSize, int value ); | |
FwStatus | fwiAbsDiffC_16u_C1R | ( | const Fw16u * pSrc, int srcStep, Fw16u * pDst, int dstStep, FwiSize roiSize, int value ); | |
FwStatus | fwiAbsDiffC_32f_C1R | ( | const Fw32f * pSrc, int srcStep, Fw32f * pDst, int dstStep, FwiSize roiSize, Fw32f value ); |
dstStep | Destination buffer step size (width of the buffer in bytes). | |
pDst | Pointer to a location in a destination buffer. | |
pSrc | Pointer to a location in a source buffer. | |
roiSize | Specifies the height and width of an ROI. | |
srcStep | Source buffer step size (width of the buffer in bytes). | |
value | Specified value. |
These functions step through an ROI in a source buffer, calculate the absolute value of the difference between the source data and a specified constant, and write the result to a destination buffer.
