Function Documentation

template<class T >

vimt3d_image_3d_of<T> vimt3d_crop	(	const vimt3d_image_3d_of< T > &	im,
		unsigned	x0,
		unsigned	nx,
		unsigned	y0,
		unsigned	ny,
		unsigned	z0,
		unsigned	nz
	)

Create windowed view of given image by specifying a cropping region in image co-ords.

The world2im transform is set so that this appears identical to im when addressed in world co-ords.

Parameters:

im	The input image.
x0	The origin (lower corner) of the cropping region in image coords.
y0	The origin (lower corner) of the cropping region in image coords.
z0	The origin (lower corner) of the cropping region in image coords.
nx	The width of the cropping region in image coords.
ny	The height of the cropping region in image coords.
nz	The depth of the cropping region in image coords.

Returns:

A cropped view of the original image.

template<class T >

vimt3d_image_3d_of<T> vimt3d_crop	(	const vimt3d_image_3d_of< T > &	im,
		const vgl_box_3d< double > &	bbox
	)

Create windowed view of given image by specifying a bounding box in world co-ords.

The world2im transform is set so that this appears identical to im when addressed in world co-ords.

Parameters:

im	The input image.
bbox	Bounding box of desired crop region in world coords.

Returns:

A cropped view of the original image.

Note:

The crop region may be expanded slightly as required to fit the voxel grid.

If the crop region extends outside the image, it is truncated to fit the image.
