Function Documentation

Fill()

void Fill	(	Pyramid< A > &	pyramid,
		uint8_t	value
	)

Fills pixels data of images in the pyramid by given value.

Parameters

[out]	pyramid	- a pyramid.
[in]	value	- a value to fill the pyramid.

Copy()

void Copy	(	const Pyramid< A > &	src,
		Pyramid< A > &	dst
	)

Copies one pyramid to another pyramid.

Note

Input and output pyramids must have the same size.

Parameters

[in]	src	- an input pyramid.
[out]	dst	- an output pyramid.

Build()

void Build	(	Pyramid< A > &	pyramid,
		::SimdReduceType	reduceType,
		bool	compensation = true
	)

Builds the pyramid (fills upper levels on the base of the lowest level).

Parameters

[out]	pyramid	- a built pyramid.
[in]	reduceType	- a type of function used for image reducing.
[in]	compensation	- a flag of compensation of rounding. It is relevant only for SimdReduce3x3 and SimdReduce5x5. It is equal to 'true' by default.

Scale()

SIMD_INLINE Point< ptrdiff_t > Scale	(	Point< ptrdiff_t >	size,
		int	scale = 2
	)

Scales size of an image.

Note

This function is useful for Pyramid structure.

Parameters

[in]	size	- an original image size.
[in]	scale	- a scale. It must be a multiple of 2. By default it is equal to 2.

Returns

scaled size.
