"Toward sustainable compost use: Prediction of organic matter via smartphone image analysis" with Dr. David C. Weindorf
Compost needs to be regularly tested to ensure labels regarding organic matter, nutrients, and more remain accurate. However, getting compost tested is time- and cost-intensive. This episode, Dr. Weindorf joins me to discuss how developing a model to predict organic matter from cell phone pictures might make this process a whole lot easier.
Tune in to learn:
· Which factors best correlated with organic matter
· How the team collected 157 different compost samples
· How application can affect the acceptable window for success on accuracy
· What camera-related factors affected the methods and results
