Flare, an optical phenomenon resulting from unwanted scattering and reflections within a lens system, presents a significant challenge in imaging. The diverse patterns of flares, such as halos, streaks, color bleeding, and haze, complicate the flare

Multiplicity of solutions to a degenerate elliptic equation in the sub-critical and critical cases

Autor: Bal, Kaushik, Biswas, Sanjit

Given a smooth and bounded domain $\Omega(\subset\mathbf{R}^N)$, we prove the existence of two non-trivial, non-negative solutions for the semilinear degenerate elliptic equation \begin{align} \left. \begin{array}{l} -\Delta_\lambda u=\mu g(z)|u|^{r-

Learning constitutive relations from experiments: 1. PDE constrained optimization

Autor: Akerson, Andrew, Rajan, Aakila, Bhattacharya, Kaushik

We propose a method to accurately and efficiently identify the constitutive behavior of complex materials through full-field observations. We formulate the problem of inferring constitutive relations from experiments as an indirect inverse problem th

Panoptic Diffusion Models: co-generation of images and segmentation maps

Autor: Long, Yinghan, Roy, Kaushik

Recently, diffusion models have demonstrated impressive capabilities in text-guided and image-conditioned image generation. However, existing diffusion models cannot simultaneously generate a segmentation map of objects and a corresponding image from

Classifying Simulated Gait Impairments using Privacy-preserving Explainable Artificial Intelligence and Mobile Phone Videos

Autor: Reddy, Lauhitya, Anand, Ketan, Kaushik, Shoibolina, Rodrigo, Corey, McKay, J. Lucas, Kesar, Trisha M., Kwon, Hyeokhyen

Accurate diagnosis of gait impairments is often hindered by subjective or costly assessment methods, with current solutions requiring either expensive multi-camera equipment or relying on subjective clinical observation. There is a critical need for
