Step-by-Step Tutorials for Common ImageJ Homework Tasks

1. Measuring Object Size in an Image

One of the most common tasks in ImageJ homework is measuring object size. Follow these steps:

Open ImageJ and load your image (File > Open).
Set the scale using a known reference (Analyze > Set Scale).
Use the “Analyze Particles” tool to detect objects (Analyze > Analyze Particles).
Save your results as a CSV file for further analysis.

2. Counting Cells in a Microscopy Image

Cell counting is a fundamental task in biology. Here’s how to do it:

Convert the image to grayscale (Image > Type > 8-bit).
Apply a threshold to segment the cells (Image > Adjust > Threshold).
Use the “Analyze Particles” function to count cells automatically.
Export the data for reporting.

For a detailed tutorial, visit ImageJ Cell Counting Guide.

3. Image Contrast and Brightness Adjustment

Enhancing image contrast and brightness is crucial in image analysis:

Open your image.
Go to Image > Adjust > Brightness/Contrast.
Use the sliders to enhance image visibility.
Apply changes and save the modified image.

4. Automating Repetitive Tasks with Macros

If you have multiple images that require the same processing steps, scripting can save you time. Here’s a basic macro example:

run("8-bit");
run("Threshold", "method=Otsu");
run("Analyze Particles", "size=50-200 circularity=0.50-1.00 show=Outlines");

To learn more about scripting, check out the ImageJ Macro Guide.
