Staff Systems Design Engineer @ KLA-Tencor System, software and algorithm design and development for wafer inspection. From 1997 to 1999 (2 years) San Francisco Bay AreaSenior Staff Systems Engineer @ Nanometrics Algorithm design and software development. Semi-conductor component data analysis. – Image processing, pattern recognition, machine learning, neural network applications. Portland, Oregon AreaSenior Computer Vision Engineer @ Immersive Media Algorithm and software development for panoramic image processing. Win/Mac, OpenCV, Python.• Implemented a new semi-automatic procedure for camera set intrinsic and extrinsic calibration.• Prototyped image feature detection and matching algorithms for automatic de-ghosting stereoimages for panoramic stitching. From 2015 to 2016 (1 year) Portland, Oregon AreaSenior Software Engineer / Imaging Scientist @ onOne Software Algorithm and software development for photographic image processing products. · Computer vision. Computational photography. Perfect Photo Suites.· Developed an image de-noising tool that competes with the recognized leading method in the field. Sparse representation. Machine learning. Invented a new filter for de-noising that overcomes some shortcomings of the median filter.· Designed and developed an image content-aware filling tool that matched or surpassed the market benchmark in both quality and speed through, among other tasks, improving the method for image stitching. · Computational effects. High-speed image segmentation on both CPU and GPU. · Built the core for a new product for portrait image processing. Detection and mapping of faces and facial features. Image segmentation / classification. Edge detection. · Single-image super resolution. Performance optimization. · C/C++, OpenCV, ITK, Matlab, threading, OpenCL, Qt; Win/Mac. From 2010 to 2014 (4 years) Portland, Oregon AreaSenior Staff Engineer @ Datalogic Scanning · Super resolution reconstruction: Algorithms generated images with higher resolution than the inputs, and led to successful decoding of bar codes acquired at a resolution below one pixel per module – the first in the industry. · Blind image de-noising and de-blurring. Algorithms led to successful recognition of 2D bar codes that originally failed to decode due to unfavorable conditions.· Restoration of 1D signal, edge detection and locating. The new algorithms led to significant increases in both speed and decoding rate.· Efficient image feature detection and location,· Other projects include analyzing, verifying and expanding legacy code for Reed-Solomon coding and error correction. Embedded code optimization. From 2005 to 2009 (4 years) Eugene, Oregon AreaPrincipal Senior Software / Vision Engineer @ Electro Scientific Industries, Inc.
