Convolutional Neural Net-Based Cassava Storage Root Counting Using Real and Synthetic Images por Atanbori, John, Montoya Pizarro, Maria Elker, Selvaraj, Michael Gomez, French, Andrew P., Pridmore, Tony P.

“…However, occlusion of both storage and fibrous roots makes the process both time-consuming and error-prone. While Convolutional Neural Nets have shown performance above the state-of-the-art in many image processing and analysis tasks, there are currently a limited number of Convolutional Neural Net-based methods for counting plant features. …”
