ImageJ Tutorial 2 - Measure Canopy Width & Area

This is the second in our lab's series of ImageJ Tutorials! This tutorial is all about measuring canopy width and area!
In this video we:
1 - 0:33 - Capture field photographs
2.1 - 3:07 - Determine scale
2.2 - 7:14 - Set scale in ImageJ
3 - 8:12 - Measure canopy width
4. - 8:47 - Measure canopy area

Thanks for these very practical videos! How important is it to hold the camera on the selfie stick in a level plane over the bed? Should I take extra measures to assure that my camera is exactly parallel to the plane of measurement or is estimating good enough? It is a lot of extra work if it doesn't introduce much error.

Hello
thanks for the video, I found ot really useful. Is there a way to automatize all the steps for a set of pictures, within ImageJ ?

Hi
Is it possible to export a tiff with geographic coordinates to import in QGIS?

[@brendaoliveiradosreis752]

it's possible measures of area of color image ? Or its only for pictures transformed in "8 bits" ? My image dont have white background, because of my experiment. Can someone help me ?

Unfortunately, area measurements can be performed only after images are converted from color to binary (black & white). If there is sufficient contrast between the object of interest and background, this method can remove the background. After that, you can convert the image to binary and perform the measurement. Please let us know if you have additional questions!
