You need to be more specific about what wave properties you are trying to detect. Link to comment Share on other sites More sharing options...
Dan9191 Posted August 5, 2019 Author Share Posted August 5, 2019 Range of Wavelengths (nm) and Range of Frequencies (Hz) please Link to comment Share on other sites More sharing options...
Sensei Posted August 5, 2019 Share Posted August 5, 2019 (edited) You can convert RGB value of pixel to wavelength and/or frequency. Find HSB (aka "HSV") color space conversion routine. Hue is almost exactly matching 700 nm ... 400 nm. https://en.wikipedia.org/wiki/HSL_and_HSV (math formulas are in the middle of the article) Edited August 5, 2019 by Sensei Link to comment Share on other sites More sharing options...
Strange Posted August 5, 2019 Share Posted August 5, 2019 32 minutes ago, Dan9191 said: Range of Wavelengths (nm) and Range of Frequencies (Hz) please Sounds like you need a program that will do a Fourier transform (and histogram) of the image. I am not aware of anything that will run on a phone. You might have to download the image and use a PC-based tool. Link to comment Share on other sites More sharing options...
