Guess I haven’t shared much about the image analysis and processing side of my project yet, since it’s come up perhaps I should. My project is all about a specific type of image processing. The macro I am working on is intended to make a normally invisible “realm” visible. I call it, Digital Phantom Leaf Photography.
Essentially, a portion of a fresh picked leaf that is roughly the size of a dime is removed. The resulting hole along with some of the surrounding leaf is then photographed against an extremely uniform white background. This is the image I work with.
There is some controversial evidence from researchers in the past suggesting that when the physical portion of a leaf is removed something called a “nonphysical”,or “phantom” leaf continues to exist for some amount of time in the empty space. Past researchers using Kirlian (high voltage, corona discharge photography) claimed that physical world leaf structures, like leaf veins, could be seen in their phantom leaf images.
As a fellow with curiosity, and being a retired engineer with time on my hands, I’ve been working off and on for a few years at developing image processing tools to create a simplified, safer form of the old high voltage, corona discharge phantom leaf photography.
The theory is that light passing through hole in the leaf will interact with whatever these phantom leaf structures are. And, that the light intensity pattern falling on a digital camera’s sensor will be affected enough to be detectable as variations in light intensity.
To make these light intensity variations visible every shoe-string-budget effort is made to limit camera sensor noise, and to provide as close as possible to a perfectly uniform white background when taking the pictures.
But the most critical part of the process, the part that makes the invisible, visible, is the image processing and pseudocoloring to be done by the macro I am developing. Like the TV weatherman’s pseudocolored maps that show temperature variations, variations in light intensity can be pseudocolored to show what can’t be seen with the naked eye in my images. My present macro project is to pseudocolor light intensity variation in my digital phantom leaf images. Eventually I want this macro to become a stand alone program I can give to anyone with the curiosity to discover the truth about phantom leaves, and to ponder the implications of their existence. Ultimately, I’d like to see scientists doing this kind of exploration and discovery.
There’s a detailed description of the project on my website for anyone that’s interested at:
At the bottom of that page are a couple of Digital Phantom Leaf photographs I created years ago using the old Filtermeister plugin software and lossy jpg image files. These images strongly suggest the existence of phantom leaf vein structures.
Some time after I originally posed those photos on my website a Frenchman who writes image processing software, in Delphi, replicated my work. He used the description on my website of what I had done to that point to create an image processing program. His program is able to show about the same level, or a little better, phantom vein structures in his .jpg images. On my website you can scroll down to see some of his images at:
So, there you have it. What I am working on is an image processing macro. With the help of folks at this Forum I’m making progress toward my goal. Success at this point means better control of all the image processing factors to get higher resolution, more definitive images.
Thanks again for all your help.
