Hi, I am working on crab ecology. To study their foraging ecology I want to use Photo Quadrate Analysis. Since, I am a new user not much familiar with ImageJ. Can anybody help me with :
- How to draw grid lines on an image (of exact match, same as in used to estimate percentage cover in a quadrate)?
- How to measure diameter of a crab’s burrow?
- How to make drawings permanent on an image (screen capture is not giving good quality image)?
This is the photo quadrate I want to analyse for particle count, area of exposure, distance between burrows, burrow opening diameter, particle size and grid lines if possible. (size is 0.25 cm2)
