II. Using Image J to animate a series of images
III. Making measurements with ImageJ.
One advantage of ImageJ (and NIH Image) is that this program allows you to make measurements directly from the images. For example, ImageJ will easily measure line length, angles, perimeter and area. You can calibrate your measurements to record the units in "real" units. It is also possible to compare images with one another by using the Image Math command. This is helpful when comparing two images. To take advantage of these features, consult the documentation with ImageJ. To make measurements of the images that will be in your movie:
IV. Using Image J to Make a Montage of Images and a Flipbook.
ImageJ will allow you to print a page with a series of images (a montage) or to make a flipbook (remember them from your childhood). To do this:
