Latest Patents

One of his latest patents is titled "Lapran: a scalable laplacian pyramid reconstructive adversarial network for flexible compressive sensing reconstruction." This invention addresses the single-image compressive sensing (CS) and reconstruction problem. LAPRAN facilitates high-fidelity, flexible, and fast CS image reconstruction by progressively reconstructing an image through multiple stages of reconstructive adversarial networks (RANs). At each pyramid level, CS measurements are fused with a contextual latent vector to generate a high-frequency image residual. Consequently, LAPRAN can produce hierarchies of reconstructed images, each with incremental resolution and improved quality. The scalable pyramid structure of LAPRAN enables high-fidelity CS reconstruction with a flexible resolution that adapts to a wide range of compression ratios (CRs), which is infeasible with existing methods.

Another notable patent is the "Generic compression ratio adapter for end-to-end data-driven compressive sensing reconstruction frameworks." This invention provides a compression ratio (CR) adapter (CRA) for end-to-end data-driven compressive sensing (CS) reconstruction (EDCSR) frameworks. EDCSR frameworks achieve state-of-the-art reconstruction performance in terms of speed and accuracy for images and other signals. However, existing EDCSR frameworks cannot adapt to a variable CR. The CRA framework addresses this variable CR problem for existing and future EDCSR frameworks without requiring modifications to the given reconstruction models or extensive additional training. The CRA exploits an initial reconstruction network to generate an initial estimate of reconstruction results based on a small portion of acquired image measurements.
