| coeffs[3][3] | Coefficients for Warp Affine Perspective transform. | |
| dstRoi | Destination image ROI. | |
| dstStep | Destination buffer step size (width of the buffer in bytes). | |
| interpolation | Specifies the method of interpolation. | |
| pDst | Pointer to a location in a destination buffer. | |
| pDst[3] | Pointer to a location in a three-channel planar destination buffer (array values point to a location in each plane). | |
| pDst[4] | Pointer to a location in a four-channel planar destination buffer (array values point to a location in each plane). | |
| pSrc | Pointer to a location in a source buffer. | |
| pSrc[3] | Pointer to a location in a three-channel planar source buffer (array values point to a location in each plane). | |
| pSrc[4] | Pointer to a location in a four-channel planar source buffer (array values point to a location in each plane). | |
| srcRoi | Source image ROI. | |
| srcSize | Source image size. | |
| srcStep | Source buffer step size (width of the buffer in bytes). |
These functions step through a source ROI, perform an inverse warp perspective transform on the source data, apply a specified method of interpolation, and write the data to a destination ROI.
Edge smoothing interpolation is applicable only when the destination quadrangle is completely within the destination image ROI.
The following transformation formula is used.
(c00*x' + c01*y' + c02)/(c20*x' + c21*y' + c22) = x (c10*x' + c11*y' + c12)/(c20*x' + c21*y' + c22) = y Where cij represents the transform coefficients
The following interpolation modes are available.
FWI_INTER_NN: nearest neighbor interpolation FWI_INTER_LINEAR: linear interpolation FWI_INTER_CUBIC: cubic interpolation
