Background:

Automatic monitoring of airborne pollen is crucial for allergy management and ecological studies.
Deep learning models have shown promise in pollen grain classification, but their performance limitations are not well understood.

Purpose of the Study:

To identify and analyze the key challenges hindering the accuracy of deep learning-based pollen classification.
To investigate why certain pollen samples and taxa are particularly difficult for deep learning algorithms.

Main Methods:

Conducted a sample-level difficulty analysis on a large, automatically generated dataset of pollen grains from microscopy images.
Utilized likelihood-based metrics to assess classification difficulty for individual samples and taxa.

Main Results:

Identified three primary challenges: (A) co-occurrence of multiple pollen grains in single images, (B) occlusion of pollen markers in 2D microscopy images, and (C) lack of unique, salient features in certain pollen taxa.
The analysis revealed specific reasons for classification errors in deep learning models.

Conclusions:

Addressing challenges like image complexity, feature occlusion, and inherent feature variability is essential for advancing deep learning in automatic pollen monitoring.
The findings provide insights for developing more robust and accurate pollen classification algorithms.
