PAC-FNO: Parallel-Structured Fourier Neural Operators for Low-Quality Image Recognition at ICLR 2024
Основные понятия
Proposing PAC-FNO for handling low-quality images with varying resolutions and natural variations in a single model.
Аннотация
Abstract:
Traditional image recognition models struggle with low-quality inputs due to resolution differences and natural variations.
PAC-FNO operates in the frequency domain, improving performance on images with various resolutions and variations.
Two-stage training algorithm fine-tunes PAC-FNO with existing models for enhanced performance.
Introduction:
Deep neural networks have revolutionized visual recognition but face challenges with low-quality inputs.
PAC-FNO addresses resolution and input variation challenges in image recognition models.
PAC-FNO Design:
AC-FNO block without band pass filters for image semantics.
Parallel configuration of AC-FNO blocks for increased capacity in learning input variations.
Evaluation:
PAC-FNO outperforms baselines in handling low-resolution images and input variations.
Superior performance in fine-grained datasets and resilience to input variations demonstrated.
Further Work:
Future applications of PAC-FNO in complex real-world scenarios with multiple input degradations.

Статистика
"Extensively evaluating methods with seven image recognition benchmarks, we show that the proposed PAC-FNO improves the performance of existing baseline models on images with various resolutions by up to 77.1% and various types of natural variations in the images at inference."
"The parameters of PAC-FNO for various backbone models are reported in the Appendix §F.2."
Цитаты
"PAC-FNO provides two advantages over existing methods: (i) It can handle both low-resolution and input variations typically observed in low-quality images with a single model; (ii) One can attach PAC-FNO to any visual recognition model and fine-tune it."
"Our proposed parallel configuration of AC-FNO blocks is effective in low-resolution image recognition."
