I am new to the forum but have used ImageJ previously for morphometrics research in fish. Now my research has gone in a slightly different direction and I am finding myself with thousands of photos of intertidal epifauna with scale bars that need to have organisms identified and counted in each. Speaking to other researchers and reading Schulze et al. 2013 PlanktoVision – an automated analysis system for the identification of phytoplankton and Mallard et al. 2013 An automated image analysis system to measure and count organisms in laboratory microcosms, I am hopeful that I can use ImageJ to create an image recognition program which can code organisms in order to be counted and recognized in later photographs. However, the organisms I’m working with are sponges, coral, barnacles, oysters, algae, etc. My searching for a program or software that could do such and already exists has thus far been fruitless. Has anyone heard of such a program? What are the opinions of the forum members so to whether this is possible to do with ImageJ? Thank you for any input or advice you may have.
