How to use ImageJ Software for Leaf Area Measurement

My student Mr Harsh Yadav prepared this video during his master's dissertation work at Nalanda University to facilitate other students to learn how to use the ImageJ program for Leaf Area Measurement. Although this video was prepared for leaf herbivory measurement, it can also be used for all other leaf traits like leaf area, leaf perimeter, leaf width, length, etc. Video production credit: Harsh Yadav
