Method Detail

getBoundingBox

public static Box3D getBoundingBox(ij.ImageStack src)

Computes a bounding box for an image. A bounding box attempts to exclude voxels with value zero that are close to image borders.

Parameters:

src - Input image (GRAY8).

Returns:

Bounding box for non-zero voxels.

duplicateEmpty

public static ij.ImageStack duplicateEmpty(ij.ImageStack src)

Create new image of the same type and size as the input image.

Parameters:

src - Input image.

Returns:

Duplicate of src without copying voxel values.

clip

public static ij.ImageStack clip(ij.ImageStack src,
                 Box3D voi)

Clip image src to volume of interest voi.

Parameters:

src - Input image.

voi - Volume of interest.

Returns:

Clipped image.

decodeOrigin

public static Point3D decodeOrigin(ij.ImagePlus imp)

Decode value of the origin property of image imp. The origin is stored in property values 'origin.x', 'origin.y', and 'origin.z'. If a properly is missing or cannot be parsed as a number it is assumed to be equal zero.

Parameters:

imp - Input image.

Returns:

Point representing the origin.

offsetOrigin

public static void offsetOrigin(ij.ImagePlus imp,
                Point3D offset)

Add offset to the value of the origin property of image imp.

Parameters:

imp - Input image.

offset - Value of the offset.

decodeOrigin(ij.ImagePlus)

encodeOrigin

public static void encodeOrigin(ij.ImagePlus imp,
                Point3D origin)

Add origin property to image imp.

Parameters:

imp - Input image.

origin - New value of the origin.
