Senior Research and Development Engineer
ARM Holdings.
Principle investigator of a machine learning project for video analytics • Learning machine systems based on
histogram of gradient and support vector machine (built it from scratch) • Detection of faces, upper body,
pedestrians and hand gestures • Correctly identify the pose of the object and different degrees of tilting • Developed
grouping and tracking algorithms • Handled occlusion problems • The main developers for the aforementioned
project • Targets the NVIDIA Tesla GPU using CUDA C • Perform algorithmic and software optimisations • Other
projects include optimisations on ARM Mali GPU using OpenCL • Programmed in Embedded C, CUDA C and OpenCL.
Achievements: Building from scratch in 6-8 months the state-of-the-art learning machine systems. High detection
rate (>90%) and low false positive rate (<0.5%). The GPU-powered learning machine has been successfully
delivered to the clients.
