Pavan Kumar Sathya Venkatesh

I'm working across several areas in computer vision - from medical image classification and plant disease detection for precision agriculture to multi-modal learning that combines audio and visual data. I've also explored neural surface reconstruction and am eager to deepen my work in this area. This lets me address meaningful real-world problems while diving deep into the technical challenges each domain presents.
