Calculates integral images for input 8-bit gray image.
The function can calculates sum integral image, square sum integral image (optionally) and tilted sum integral image (optionally). A integral images must have width and height per unit greater than that of the input image.
- Note
- This function has a C++ wrappers:
Simd::Integral(const View<A>& src, View<A>& sum),
Simd::Integral(const View<A>& src, View<A>& sum, View<A>& sqsum),
Simd::Integral(const View<A>& src, View<A>& sum, View<A>& sqsum, View<A>& tilted).
- Parameters
-
[in] src - a pointer to pixels data of input 8-bit gray image. [in] srcStride - a row size of src image. [in] width - an image width. [in] height - an image height. [out] sum - a pointer to pixels data of 32-bit integer sum image. [in] sumStride - a row size of sum image (in bytes). [out] sqsum - a pointer to pixels data of 32-bit integer or 64-bit float point square sum image. It can be NULL. [in] sqsumStride - a row size of sqsum image (in bytes). [out] tilted - a pointer to pixels data of 32-bit integer tilted sum image. It can be NULL. [in] tiltedStride - a row size of tilted image (in bytes). [in] sumFormat - a format of sum image and tilted image. It can be equal to SimdPixelFormatInt32. [in] sqsumFormat - a format of sqsum image. It can be equal to SimdPixelFormatInt32 or SimdPixelFormatDouble.
