Analysis of 3D Urticaceae Pollen Classification Using Deep Learning Models
This work addresses hay fever monitoring by improving pollen classification for healthcare and municipal planning, but it is incremental as it applies existing deep learning models to a new 3D dataset.
The paper tackled the problem of classifying 3D pollen images from the Urticaceae family to monitor allergenic trends, achieving a best performance of 98.3% F1-score using a pre-trained ResNet3D model.
Due to the climate change, hay fever becomes a pressing healthcare problem with an increasing number of affected population, prolonged period of affect and severer symptoms. A precise pollen classification could help monitor the trend of allergic pollen in the air throughout the year and guide preventive strategies launched by municipalities. Most of the pollen classification works use 2D microscopy image or 2D projection derived from 3D image datasets. In this paper, we aim at using whole stack of 3D images for the classification and evaluating the classification performance with different deep learning models. The 3D image dataset used in this paper is from Urticaceae family, particularly the genera Urtica and Parietaria, which are morphologically similar yet differ significantly in allergenic potential. The pre-trained ResNet3D model, using optimal layer selection and extended epochs, achieved the best performance with an F1-score of 98.3%.
