borongzhang/back_projection_diffusion
Code for the main models described in “Back-Projection Diffusion: Solving the Wideband Inverse Scattering Problem with Diffusion Models”.
This project helps scientists and engineers reconstruct detailed images of an object's internal structure from its wideband scattering data. You input the wave scattering measurements, and it outputs highly accurate images of the refractive index, even for complex or subtle features. This tool is for researchers in fields like medical imaging or materials science who need to "see through" objects using wave data.
No commits in the last 6 months.
Use this if you need to accurately determine the internal refractive index of an object from wideband wave scattering data, especially when traditional methods struggle with resolution or complex scattering.
Not ideal if you are working with narrowband scattering data or if your primary goal is not high-resolution internal structure reconstruction from wave measurements.
