Figure out if the yellow is localized to a quadrant or is all over the leaf.

Figure out how yellow each quadrant is.

Divide an RGB image of a leaf into four quadrants at the leaf’s centroid.

Ah…but why stop because someone else (Oh alright – several folks) said I can’t do math…

SELECT WINDOW THRESHOLD IMAGEJ MACRO LANGUAGE HOW TO

My biggest challenge with implementing the algorithm described in the document was a lacking in how to interpret the math language as well as my general fear of math. The color analysis algorithm I will use was proposed in the article Smart Sensor for Real-Time Quantification of CommonSymptoms Present in Unhealthy Plants . The ImageJ macro and images used in this post are located at this Github location. This post uses the knowledge I gained within the course.

Paul Fisher for teaching the excellent University of Florida’s Nutrient Management 2 (Advanced). Sharma pointed out to get only the leaf pixels in the quadrant is a simple task of taking the intersection of the leaf selection with a quadrant.ĭr. Chopping led me to understand how getting the bounding rectangle (i.e.: run(“Set Measurements…”, “area bounding redirect=None decimal=2”) ) is critical to finding these quadrants. These two wonderful folks answered a question I had on how to create selections based on quadrants of the images. Ved Sharma, Albert Einstein College of Medicine. Mark Chopping, Montclair State University and Dr. The folks behind the ImageJ and Fiji software, especially Wayne Rasband, the NIH, and the large community of folks that improve on this valuable resource.ĭr.

The code will work but probably just barely.

SELECT WINDOW THRESHOLD IMAGEJ MACRO LANGUAGE MAC

The goal of this post is to take an image of a leaf and have my Mac tell me the overall and localized level of chlorosis. One of the big visual clues is when all or part of a leaf turns yellow. While plants are poor communicators, they do offer visual clues when they are getting not enough or too much of a nutrient. And who knows…down the road this knowledge might come in handy. Still – ever grateful (seriously) that my family cares enough to ask! I crave the thrill of learning how to do something I am clueless about. You are indeed right….and yet…I bumble onward in this effort.

All the while thinking if I mentioned this to my family they would say something…”can’t you just look at the leaf?” Yes family.

Take a snapshot of volume at your desired angle(s) and save.I woke up awhile back extremely excited to answer the question if I could use a picture and image processing to help isolate nutrient deficiencies or toxicities.

Ensure that the selected “Mode” is set to volume.

Run the plugin – it may take several minutes to load.

This plugin uses a fair bit of memory, so you may need to scale down your image in order for the process to run. Volume Viewer: This plugin allows you to view a 3D volume of a fluorescent Z-stack and has more settings and options allowing you to customize your projection.

This may take a fair amount of trial and error and works best on a computer with a good graphics card Increase the resampling factor to “smooth” the image. Ideally, you want your reconstruction to be one piece without “holes”, so lower the threshold if you need to fill in the holes. In the Image Viewer window, export File > Export > STL (ASCII).Change “Display As” from Volume to Surface.Select the image and write in file name.Ensure you are using an 8-bit image by selecting Image > Type > 8-bit.A polygon mesh is a collection of triangles (vertices, edges and faces) that defines the shape of an object in 3D computer graphics. This rendering can be used as a polygon mesh for a 3D model.

Geometric Surface Rendering: The surface is defined by a series of connected triangles.

avi with no compression- and then click on it to watch your movie!

Try the project without and with interpolate checked to see if gaps need to be filled.

Set the project method (start with brightest point) and the axis of rotation (your preference).

To make the 360-degree video of the projection, go to Image > Stacks > 3D Project.

Adjust image contrast with histogram stretching.

Open Z-stack in Fiji with hyperstack selected.

This includes linear interpolation between the actual data planes and then transparent volume rendering for visualization.

If you would like to change the color, go to Image > Look Up Table > and select desired color.ģD Reconstruction/Volume Rendering: Mathematical reconstruction of Z-stacks to produce a three-dimensional volume.

Choose your “Start” and “Stop” slice and type of projection (Maximum).

Open Z-stack in Fiji, under Color Options/color mode choose “Colorize”.

Maximum Intensity Projection is an algorithm that selects pixels of the highest intensity from every slice throughout the volume to construct a 2D image.
