Image-based Phenotyping of Nematodes
Nematodes (roundworms) constitute a highly diverse animal phylum. Up to 4100 species of plant parasitic nematodes are currently identified and many species are parasitic on crops, such as potatoes, sugar beets and soybeans, causing up to 180 billion US dollars of economic losses annually in agriculture worldwide. High-throughput analysis of nematodes from the soil sample would allow fast quantifying nematode infestation and characterizing nematode populations through extraction of phenotypic features, thus pushing cyst monitoring and resistance screening of plants an important step forward.
Overall aim of this research project is to build a high-throughput system for analysis of nematodes in the soil sample, including nematode cysts, eggs and juveniles. A robust instance segmentation is the key step, which is challenging due to the highly clutterd collection in the image and unavailability of public training data.
