    Deconvolution

    671
    Deconvolution, also known as inverse filtering, is the process of extracting the impulse response from known input and output signals. This technique is vital in scenarios where the system's characteristics are unknown, and they must be inferred from the observable signals.
    Deconvolution involves several mathematical techniques to derive the impulse response. One common approach is polynomial division. In this method, the input and output sequences are treated as coefficients of...

    This study introduces a new quantum deep image prior (QDIP) method to solve challenging multispectral unmixing (MU) problems. The geometry/quantum-empowered MU (GQ-μ) algorithm effectively analyzes material spectra from satellite images.

    Area of Science:

    • Remote Sensing
    • Signal Processing
    • Quantum Computing

    Background:

    • Multispectral unmixing (MU) is crucial for analyzing satellite imagery but is challenging due to limited spatial resolution and underdetermined blind source separation.
    • Existing methods struggle with the ill-posed nature of MU, where the number of sources exceeds available spectral bands.

    Purpose of the Study:

    • To develop a novel algorithm for accurate multispectral unmixing (MU) by transforming it into a hyperspectral unmixing (HU) problem.
    • To introduce a quantum deep image prior (QDIP) for virtual hyperspectral image generation and a weighted simplex shrinkage (WSS) regularizer for improved unmixing.

    Main Methods:

    • The proposed geometry/quantum-empowered MU (GQ-μ) algorithm utilizes a quantum deep image prior (QDIP) to generate a virtual hyperspectral image (HSI) from multispectral images (MSI).

  • Hyperspectral unmixing (HU) is performed on the virtual HSI, employing a geometry-inspired weighted simplex shrinkage (WSS) regularizer to address ill-posedness.
  • Virtual hyperspectral sources are spectrally downsampled to obtain multispectral sources and abundance maps.

    • Main Results:

    • The GQ-μ algorithm successfully performs unsupervised multispectral unmixing (MU), achieving high-precision classification and identification.
    • Ablation studies confirm the effectiveness of the quantum deep image prior (QDIP) over classical methods and validate the WSS geometry regularizer.
    • The algorithm demonstrates practical utility on both simulated and real-world multispectral data.

    Conclusions:

    • The developed GQ-μ algorithm offers a robust solution for the challenging multispectral unmixing (MU) problem by leveraging quantum and geometric principles.
    • The QDIP and WSS regularizer significantly enhance the accuracy and stability of the unmixing process.
    • The unsupervised nature and demonstrated effectiveness make GQ-μ a valuable tool for remote sensing applications.
