I am working with some propagating, gaseous, waves. I want to measure wave speed on the normal direction of it’s wave front.
I would like to be able to find a gradient field of a given tiff file, then find the pixels with the highest gradient values (Wave Front). Then with these points in xy space, I would potentially fit a curve on this wave front which would be updated for each consecutive slice. It would probably require a good deal of code in Python or any other software (Suggestions would be appreciated) but I would like to know how to start with getting the gradient of my tiff files first!
Here are some examples of two kinds of waves, montaged:
Thank you for any and all input!
