temporally related images in a single window. These image sets are called
stacks and are often generated in biological imaging either by timelapse
images or by Z stacks used in microscopy. The images that make up a
stack are called slices. In stacks, a pixel (which represents 2D image data
in a bitmap image) becomes a voxel (volumetric pixel), that is an intensity
value on a regular grid in a 3D space. Furthermore, ImageJ can create
and handle hyperstacks of images that are composed of multicolour
channel images having multiple slices and frames.
The image itself may have data attached to it in the form of an EXIF
data fi le and this too can be read by ImageJ and contains useful
information for outputs such as the date the image was captured and
