Synthetic benchmarking for hyperspectral super-resolution methods

Project description

HyperBench

HyperBench is a synthetic benchmarking framework for fusion based hyperspectral super-resolution (HSR) methods. It provides a standardized, reproducible pipeline for evaluating models using controlled degradations, consistent metrics, and structured experiment outputs.

HyperBench is designed as an inference-time evaluation tool. It does not perform model training. Instead, it enables users to test already-trained models under a wide range of synthetic scenarios.

Project Home: https://github.com/ritikgshah/HyperBench. Please visit the github repository for exact implementation details and documentation. This PyPi project is solely meant to serve as the distribution method.


Key Features

Synthetic Degradation Pipeline

HyperBench generates realistic low-resolution inputs from high-resolution hyperspectral scenes:

  • Spatial degradation via configurable Point Spread Functions (PSFs)
  • Spectral degradation via configurable Spectral Response Functions (SRFs)
  • Controlled noise injection using SNR (dB)

Flexible Experiment Design

Users can define experiments using:

  • Explicit degradation specifications
  • PSF configurations (type, sigma, kernel size)
  • Noise levels (spatial and spectral)
  • MSI band counts

Model-Agnostic Adapter Interface

HyperBench works with any model that follows a simple contract:

def run_pipeline(HR_MSI, LR_HSI, srf, psf=None, metadata=None): return prediction

or

return prediction, stats

Supported formats: - NumPy - TensorFlow - PyTorch


Built-in Metrics

  • RMSE
  • PSNR
  • SSIM
  • UIQI
  • ERGAS
  • SAM

Output Clipping Policy

Optional clipping to [0,1] before metric evaluation.


Structured CSV Logging

Each experiment produces structured CSV output with: - parameters - metrics - optional model stats


Visualization Utilities

  • RGB visualization
  • band inspection
  • PSF and SRF visualization
  • spectral plots

Framework Support
