Detailed Description

template<class I>
class cvr::geometricTransform< I >

Class geometricTransform.

This is an abstract template class, parent of all functors that achieve geometric transformation of images, like affine or homogeneous transformations.

The template parameter I indicates the interpolator type to be used. The class provided must be inherited from cvr::fixedGridInterpolation. Note that the interpolator works for one type of containers only, and only that type will be supported by this class too.

geometricTransform<I>::parameters.

template<class I>

virtual bool cvr::geometricTransform< I >::apply	(	const matrix< value_type > &	src,
		matrix< value_type > &	dest,
		fpoint &	offset
	)			const [pure virtual]

Transform geometrically the source image and leave the result on the destination container.

If the parameters specify to AdjustDimensions, then the offset value will contain the relative position of the srcdest origin with respect to the original image coordinate system. To all other resize policies, the value of offset is set to (0,0).

Parameters:

	src	matrix<value_type> with the source data.
	dest	matrix<value_type> where the result will be left.
	offset	position of the origin of the result with respect to the coordinate system of the original image.

Returns:

true if apply successful or false otherwise.

Implemented in cvr::matrixTransform< I >.

template<class I>

virtual bool cvr::geometricTransform< I >::apply	(	matrix< value_type > &	srcdest,
		fpoint &	offset
	)			const [virtual]

Transform geometrically the given image and leave the result on the same container.

If the parameters specify to AdjustDimensions, then the offset value will contain the relative position of the srcdest origin with respect to the original image coordinate system. To all other resize policies, the value of offset is set to (0,0).

Parameters:

	srcdest	matrix<T> with the source data. The result will be left here too.
	offset	position of the origin of the result with respect to the coordinate system of the original image.

Returns:

true if apply successful or false otherwise.

Reimplemented in cvr::matrixTransform< I >.

template<class I>

virtual bool cvr::geometricTransform< I >::apply	(	const matrix< value_type > &	src,

	)			const [pure virtual]

Transform geometrically the source image and leave the result on the destination container.

Operates on a copy of the given parameters.

Parameters:

	src	matrix<value_type> with the source data.
	dest	matrix<value_type> where the result will be left.

Returns:

true if apply successful or false otherwise.
