• Selected and tested no-reference video-quality metrics• Smoothed panning in sports videos

Tested and improved robustness of video-fingerprinting algorithms• Algorithm development and testing• Tested algorithms on embedded processors in TVs• Supported data scientists

Meta was a startup developing an augmented-reality headset (NOT the Facebook parent company). The headset included RGB and TOF depth cameras. I developed algorithms and code to reduce noise and artifacts in TOF depth images.

Developed technologies for high-throughput automatic evaluation and segmentation of images.• Evaluated and developed no-reference image-quality metrics• Developed algorithms and software to segment text from natural images

Researched and developed algorithms and code for audio and video content tracking and video segmentation. Co-inventor for 16 US patents. IP now owned by Roku.• Principal contributor for feature-extraction algorithms and code• Developed algorithms to find text and channel logos in video• Tested content-tracking system on actual digital TV channels• Measured audio distortions from hi-fi speakers, TVs and iPhones• Generated test content with real and synthetic distortions• Designed and ran feature-matching tests, which improved and sped up development• Thoroughly optimized code for speed and robustness to problems in input streams

Developed technologies for automatic content recognition. • Co-developed video/audio fingerprinting system• Tested this as submission to MPAA competition• Adapted and tested face-recognition software for movie content

Application support for technical marketing of Intel XScale ARM-based embedded processors.• Developed H.263/H.264 videoconferencing apps• Advised management and developers on codec issues• Apps demoed in trade shows

Developed algorithms to enhance the quality of images from camera phones.• Developed algorithms and code to suppress artifacts and noise in images• Deduced causes of image artifacts for coworkers and customers• Designed and participated in tests of visual quality

R&D and standards work for copyright protection and wireless networking.• Immunized video watermarks against distortions; 9 US patents as sole inventor• Evaluated proposals for anti-piracy methods and UWB wireless networking • Participated in international meetings for Sony R&D• Provided technical and cross-cultural assistance to Sony Tokyo managers
