# PFGNet: A Fully Convolutional Frequency-Guided Peripheral Gating Network for Efficient Spatiotemporal Predictive Learning

PFGNet is a fully convolutional framework for efficient spatiotemporal predictive learning (STPL), presented at CVPR 2026. It aims to forecast future frames from past observations by dynamically modulating receptive fields through pixel-wise frequency-guided gating. 

Inspired by biological center-surround organization, the core Peripheral Frequency Gating (PFG) block extracts localized spectral cues to adaptively fuse multi-scale large-kernel peripheral responses with learnable center suppression, forming spatially adaptive band-pass filters.

## Available checkpoints

This repository provides dataset-specific trained checkpoints of PFGNet on multiple benchmarks:

| Dataset | Checkpoint |
|---|---|
| Moving MNIST | `pfg_mmnist.ckpt` |
| Moving Fashion MNIST | `pfg_mfmnist.ckpt` |
| TaxiBJ | `pfg_taxibj.ckpt` |
| KTH (10→20) | `pfg_kth20.ckpt` |
| KTH (10→40) | `pfg_kth40.ckpt` |
| Human3.6M | `pfg_human.ckpt` |

## Usage

PFGNet directly inherits the codebase and dependencies of [OpenSTL](https://github.com/chengtan9907/OpenSTL). Please refer to the official repository for detailed environment setup and data preparation instructions.

### Training (Moving MNIST example)
From the repository root, run:
```bash
python tools/train.py -d mmnist -c configs/mmnist/PFG.py --ex_name mmnist_pfg --test
```

### Testing (Moving MNIST example)
From the repository root, run:
```bash
python tools/test.py -d mmnist -c configs/mmnist/PFG.py --ex_name mmnist_pfg --test
```
