public FilterGaussPyramidLayerDownBorder ( NPPImage_8uC3 dest, float nRate, int nFilterTaps, CudaDeviceVariable |
||
| dest | NPPImage_8uC3 | Destination image |
| nRate | float | The downsampling rate to be used. For integer equivalent rates unnecessary source pixels are just skipped. For non-integer rates the source image is bilinear interpolated. nRate must be > 1.0F and <= 10.0F. |
| nFilterTaps | int | The number of filter taps where nFilterTaps = 2 * ((int)((float)ceil(radius) + 0.5F) ) + 1. |
| pKernel | CudaDeviceVariable |
Pointer to an array of nFilterTaps kernel coefficients which sum to 1.0F. |
| eBorderType | NppiBorderType | The border type operation to be applied at source image border boundaries. |
| return | void | |
