Detailed Description

template<class TDb>
class SSD< TDb >

Class responsible for SSD calculation between patches of images.

Needs a reference to ImageDatabase to construct, as it must support calculating SSD between adjacent pathces in both X and Y dimensions, as well as between patches of adjacent images in database.

SSD is constructed from coordinates of centers of patches, but uses coordinates of top-left corner of patches for calculation.

Needs only index of a single image in database (>= 1) because the other image is always Database[0] (image to be segmented).

Template Parameters

TDb	Type of image database. Must be ImageDatabase.

Constructor & Destructor Documentation

SSD()

template<class TDb >

SSD< TDb >::SSD	(	const TDb &	db,
		size_t	idx,
		size_t	ctrFixedX,
		size_t	ctrFixedY,
		size_t	ctrMovingX,
		size_t	ctrMovingY,
		size_t	radius
	)

Constructor from coordinates of centers of patches.

Calculates coordinates of top-left corners of patches on images. Patches must lay inside the images, i. e. ctrFixedX >= radius, ctrFixedX < imageWidth - radius, similarly for Y coordinates.

Parameters

[in]	db	Database of images
[in]	idx	Index of moving image in database, must be >= 1
[in]	ctrFixedX	X-coordinate of center of patch on fixed image
[in]	ctrFixedY	Y-coordinate of center of patch on fixed image
[in]	ctrMovingX	X-coordinate of center of patch on moving image
[in]	ctrMovingY	Y-coordinate of center of patch on moving image
[in]	radius	Radius of patches
