Calculates Laplace's filter.
All images must have the same width and height. Input image must has 8-bit gray format, output image must has 16-bit integer format.
For every point: dst[x, y] =
- src[x-1, y-1] - src[x, y-1] - src[x+1, y-1]
- src[x-1, y] + 8*src[x, y] - src[x+1, y]
- src[x-1, y+1] - src[x, y+1] - src[x+1, y+1].
- Note
- This function has a C++ wrappers: Simd::Laplace(const View<A>& src, View<A>& dst).
- Parameters
-
[in] | src | - a pointer to pixels data of the input image. |
[in] | srcStride | - a row size of the input image. |
[in] | width | - an image width. |
[in] | height | - an image height. |
[out] | dst | - a pointer to pixels data of the output image. |
[in] | dstStride | - a row size of the output image (in bytes). |

- src[x-1, y] + 8*src[x, y] - src[x+1, y]
- src[x-1, y+1] - src[x, y+1] - src[x+1, y+1]).
- Note
- This function has a C++ wrappers: Simd::LaplaceAbs(const View<A>& src, View<A>& dst).
- Parameters
-
[in] | src | - a pointer to pixels data of the input image. |
[in] | srcStride | - a row size of the input image. |
[in] | width | - an image width. |
[in] | height | - an image height. |
[out] | dst | - a pointer to pixels data of the output image. |
[in] | dstStride | - a row size of the output image (in bytes). |

Calculates Laplace's filter.
All images must have the same width and height. Input image must has 8-bit gray format, output image must has 16-bit integer format.
For every point: dst[x, y] =
- src[x-1, y-1] - src[x, y-1] - src[x+1, y-1]
- src[x-1, y] + 8*src[x, y] - src[x+1, y]
- src[x-1, y+1] - src[x, y+1] - src[x+1, y+1].
- Note
- This function is a C++ wrapper for function SimdLaplace.
- Parameters
-
[in] | src | - an input image. |
[out] | dst | - an output image. |
