Projects

4DHumans
This project aims to capture temporally consistent sequences of humans performing different actions. The data capture system is consist of seven Microsoft Kinect cameras

3DHumans
3DHumans dataset provides 180+ high-fidelity meshes of people in diverse body shapes in various garments styles and sizes. We cover a wide variety of clothing styles, ranging from loose robed clothing, like 'saree' (a typical South-Asian dress) to relatively tight fit clothing, like shirts and trousers.

Peeled Ray Tracer
An extended version of recursive ray tracing for adding realistic lighting mechanism to peelmaps from PeeledHuman representation.

Prompt-SAM
Added CLIP-based text prompting support to Meta's Segment Anything Model (SAM).

3D Point Cloud Segmentation
Implementation of 3D point cloud segmentation using submanifold SparseConv Encoder-Decoder, integrated with Open3D-ML pipeline.

Hand Gesture Recognition
Image processing based mathematical model for detecting hands and recognizing gestures from a custom dataset created from scratch.
