Retired from The Procter and Gamble Company
Followers: 99 Following: 0
Senior Scientist (male/man) and Inventor in the Procter and Gamble Company, one of the world's 10 largest industrial corporations. I did image analysis full time until my retirement in 2023 and currently have only part time jobs with P&G. I have Ph.D. in Optical Sciences specializing in imaging, image processing, and image analysis. 45+ years of military, academic, and (mostly) industrial experience with image analysis programming and algorithm development. Experience designing custom light booths and other imaging systems. Experience with color and monochrome imaging, video analysis, thermal, ultraviolet, hyperspectral, CT, MRI, radiography, profilometry, microscopy, NIR and Raman spectroscopy, etc. on a huge variety of subjects. Member of the Mathworks Community Advisory Board. Be sure to click "View All" in my File Exchange to see ALL of my demos and tutorials.

Identify non accident properties and segment regions of concavity
You can identify concave regions by using bwconvhull and then subtracting, or doing an XOR, with the original binary image.

Transition point discontinuity (cliff/spike) in plots of solved system of non linear equations.
You could post-process your curve data to remove the spike. Perhaps findchangepts will be useful to you.
