Sirshapan (Sirsh) Mitra

PhD Student, Computer Vision — CRCV, University of Central Florida

I am a 2nd year PhD student at CRCV Lab at University of Central Florida in Orlando, USA. I work at the intersection of 3D Vision, Diffusion Generative Models, and Vision-Language Models. My research experience spans Gaussian Splatting, Diffusion Models, Gait Recognition, Biometrics, and Limited-Label Learning.
