In recent years, notable advances in the design and training of deep learning models have led to significant improvements in image recognition performance, particularly on large-scale data sets. Fine-grained image recognition (FGIR) represents a specialized domain that focuses on the detailed recognition of subcategories within broader semantic categories. Despite the progress facilitated by deep learning, FGIR remains a formidable challenge, with a wide range of applications in smart cities, public safety, ecological protection, and agricultural production.
The main obstacle in FGIR revolves around discerning subtle visual disparities, crucial for distinguishing objects with very similar general appearances but varying detailed characteristics. Existing FGIR methods can generally be classified into three paradigms: recognition using location classification subnetworks, recognition using end-to-end feature encoding, and recognition with external information.
While some methods from these paradigms have been made available as open source, a unified library of open needs is currently lacking. This absence poses a major obstacle for new researchers entering this field, as different methods often rely on disparate deep learning frameworks and architectural designs, requiring a steep learning curve for each. Additionally, the absence of a unified library often forces researchers to develop their code from scratch, leading to redundant efforts and less reproducible results due to variations in frameworks and configurations.
To address this, researchers from Nanjing University of Science and technology present Hawkeye, a PyTorch-based library for fine-grained image recognition (FGIR) built on a modular architecture, prioritizing high-quality code and readable configuration. by humans. With its deep learning capabilities, Hawkeye offers a comprehensive solution designed specifically for FGIR tasks.
Hawkeye encompasses 16 representative methods spanning six paradigms in FGIR, providing researchers with a holistic understanding of state-of-the-art techniques. Its modular design makes it easy to integrate custom methods or improvements, allowing fair comparisons with existing approaches. The FGIR training process at Hawkeye is structured into multiple modules integrated into a unified process. Users can override specific modules, ensuring flexibility and customization while minimizing code modifications.
Emphasizing code readability, Hawkeye simplifies each module within the process to improve understandability. This approach helps beginners quickly understand the formation process and the functions of each component.
Hawkeye provides YAML configuration files for each method, allowing users to conveniently modify hyperparameters related to the dataset, model, optimizer, etc. This simplified approach allows users to efficiently tailor experiments to their specific requirements.
