ObjectJ is an ImageJ plugin that supports graphical vector objects that non-destructively mark images on a transparent layer. Vector objects can display points or paths with sub-pixel resolution; they can be placed manually or by macro commands. Composite objects can encapsulate different color-coded marker structures in order to bundle features that belong together ObjectJ provides back-and-forth navigation between results and images. The results table supports statistics, sorting, color coding, qualifying and macro access. A single file such as "MyProject.ojj" is used to maintain the link between markers and measurements across many images or stacks. ObjectJ plugin have been developed to measure tree rings, eucalyptus leaves shape and cell count and measurments.
