Internship Overview

The Video Production Services team develops technologies that improve how video is produced and delivered for modern displays, with particular expertise in high dynamic range (HDR) and wide color gamut. This internship will focus on optimizing an existing neural network that converts standard dynamic range (SDR) video to HDR, then deploying the optimized model on dedicated neural processing hardware.

Technical Approach

The intern will build an end-to-end optimization workflow using techniques such as knowledge distillation and quantization. The optimized model will be benchmarked against the original, deployed to a low-power and compute-constrained target, and assessed for visual quality, output consistency, model size, latency, and runtime efficiency.

Key Responsibilities

Analyze the existing SDR-to-HDR network and establish quality, performance, and hardware constraints.

Select suitable optimization techniques and supporting tools, including knowledge distillation and quantization frameworks.

Develop a reproducible pipeline for model optimization, evaluation, and deployment.

Benchmark the optimized model against the original for visual quality, output consistency, model size, latency, and computational efficiency.

Deploy and validate the optimized model on a dedicated neural processing architecture.

Document the methodology, results, limitations, and recommendations.

Candidate Profile

Required Qualifications

Currently pursuing a master’s degree in computer science, electrical engineering, applied mathematics, or a related discipline.
