Kaustubh Sadekar

I am a Computer Science Ph.D. student at Portland State University, advised by Prof. Atul Ingle. My research interests include 3D computer vision, computational Imaging, and Design of Synthetic dataset generation pipelines.

Previously, I was a Senior Research Fellow at the Computer Vision Graphics and Imaging Lab of IIT Gandhinagar, supervised by Prof. Shanmuganathan Raman. Before that I worked at the Autonomous Robots and Multi-robot Systems (ARMS) Lab of the Indian Institute of Technology Bombay as a Research Associate supervised by Prof. Leena Vachhani and Prof. Abhishek Gupta.

OpenCV Spatial AI Competetion Phase 1 Winners

FUNdamentals of CV

A series of fun projects explaining classical computer vision and image processing topics like calibration, camera projection, color detection etc.

Interactive 3D window using Numpy and OpenCV

Python and C++ implementation for perspective camera projection using OpenCV and Numpy to create an interactive 3D window effect. Also implimented a Kalman filter for smooth face traciking.

SPARK - OpenCV and ROS based robotic sketching arm

A low cost 3DOF robotic sketching arm was fabricated and developed using inexpensive servo motors. A visual feedback system, utilizing ArUco markers, was designed for efficient performance, and closed loop position control of the arm joints was implemented.

Fun mirrors using OpenCV

Created a virtual camera model and used mesh based warping to generate sum fun effects.

Invisibility cloak using OpenCV

Used OpenCV for color based segmentation to create a fun application of invisibility cloak.

Air drums using OpenCV

Used color based segmentation to create a fun application to play drums in air!
