| FwStatus | fwiFilterSobelCross_8u16s_C1R | ( | const Fw8u * pSrc, int srcStep, Fw16s * pDst, int dstStep, FwiSize dstRoiSize, FwiMaskSize mask ); | |
| FwStatus | fwiFilterSobelCross_8s16s_C1R | ( | const Fw8s * pSrc, int srcStep, Fw16s * pDst, int dstStep, FwiSize dstRoiSize, FwiMaskSize mask ); | |
| FwStatus | fwiFilterSobelCross_32f_C1R | ( | const Fw32f * pSrc, int srcStep, Fw32f * pDst, int dstStep, FwiSize dstRoiSize, FwiMaskSize mask ); |
| dstRoiSize | Destination image ROI size. | |
| dstStep | Destination buffer step size (width of the buffer in bytes). | |
| mask | An analysis window (only non-zero mask array values are processed). | |
| pDst | Pointer to a location in a destination buffer. | |
| pSrc | Pointer to a location in a source buffer. | |
| srcStep | Source buffer step size (width of the buffer in bytes). |
These functions step through an ROI in a source buffer, apply a second cross derivative Sobel operator to the source data, and write the filtered data to a destination buffer.
The functions operate on either a 3X3 or 5X5 mask.
These functions enhance and smooth the horizontal edges of an image.
