Advanced Remanufacturing and Technology Centre
(ARTC), A*STAR Development Scientist [ Aug 2019 – Present ]
Led a project on Proof of Concept Digital Twin implementation of the supply chain 4.0 aiming towards industry 4.0 in collaboration with Procter & Gamble
(P&G), Singapore to optimize production planning; to achieve accurate demand forecast using business model strategies (ARIMA and Supervised learning models using CNNs) that will help in achieving cost savings on manpower and resource utilization (on-going).
Created a REST API call to send the data information about purchased items to either the Raw-material server or to the sub-assembly server to be stored in respective databases (InfluxDB, MySQL DB).
Implemented obstacle avoidance and explored precise localisation capabilities of SLAM by using Intel Realsense from a video feed that will help in real-time 3D obstacle detection and avoidance for Auto-guided vehicles (AGVs) in ROS environment.
Designed a web-interface (UI/ UX) for user-interactive purchase order system that helped in prior suggestions based on a customer’s order history and to keep a track on purchase orders and display the purchased items on a webpage.
End-to-end development of AI based decision-aiding system for energy consumption of gearbox assembly that increased the energy efficiency by 20%.
Handled the development of adaptive pricing model (using Machine learning models) for the manufactured gearbox items based on the energy consumption efficiency (on-going).
Currently managing a team of 10+ researchers and full-time developers, providing guidance on technical and inter-personal aspects. Nanyang Technological University (NTU), Singapore PhD. Candidate [ Aug 2014 – Aug 2019 ]
Innovated and researched new algorithms and models on 3D RECONSTRUCTION: INVESTIGATION OF ACCURATE FRINGE ANALYSIS TECHNIQUES FOR FRINGE PROJECTION PROFILOMETRY (FPP)
Developed a structured light FPP system for 3D scanning using well-known calibration and image enhancement techniques.
First ever team (a group of 3 people) to incorporate GPU acceleration for fringe analysis for a high-speed 3D scan and reconstruction that achieved a real- time processing speed of 30 frames/sec.
Mathematically analysed the issues associated with an FPP system such as shadowing around the curved areas etc.
Proposed novel computer vision techniques (both automatic and user-interactive) to eliminate these issues in MATLAB and C++. University of Trieste, Italy Research Associate [ May 2013 – Jul 2013 ]
Analysed H.264 codec to measure and reduce the blocking artefacts in video frames using DCT; monitored real-time video quality using C++. Indian Institute of Technology (IIT) Jodhpur, India Research Intern [ May 2012 – Jul 2012 ]
Developed a novel edge preserving filter-based salt and pepper noise removal technique that helped remove more than 90% of the noise effectively. Indian Institute of Technology (IIT) Jodhpur, India Research Intern [ May 2011 – Jul 2011 ]
Implemented a least squares-based prediction scheme for image interpolation; achieved a reduction of upto 60-70% in computational efficiency. OTHER PROJECTS & EXPERIENCE
Engineered a face recognition and matching system (using TensorFlow) based on Caltech dataset that analysed the similarity quotient between two images to identify whether they are same or not.
Explored the possibility of AI in 3D measurements using neural networks.
Developed a user-interactive interface (using MeshView) to control objects using hand-gestures using Leap motion.
Embedded an image watermarking scheme to analyse the effect of different prediction schemes that can recover the original image later with 90% accuracy.
Awarded with Excellence in Teaching Assistantship by NTU for exemplary performance.
Awarded with NTU Research Scholarship from Aug 2014 to Aug 2018.
Served as a student leader (president) of Graduate Student Club at NTU for a year.
Organiser @ TedX NTU: Organised TedX events at NTU for 2 years consecutively.
Organiser @ LNMIIT: Organised a workshop on Digital Image Processing single handily at LNMIIT in 2013.
Secured 2nd position in an intra-university hackathon competition at LNMIIT. SKILLS
