“There are so many things I’d like to see happen, and I have the privilege of leading people who share the same vision.” sift through hundreds of images to make a collage of the best photos. Moreover, they work in real time, opening up new avenues for improvement in devices like smart home assistants that constantly monitor their surroundings. The common language of Pixel Intelligence and Lin’s current research is an area known as computer vision, a branch of AI that helps computers to understand visual information. In recent years, computer vision tasks have become more accurate with machine learning models. “At HP, we’ve started using it to enhance our ability to understand images,” she says. This creates potential commercial applications and new capabilities such as in social sharing. When you upload a photo on a social media site, the application downsizes the photo so it’s faster to transmit, which reduces the quality of photos. Lin and her team have looked at using deep learning to scale up these photos for large-format printing. They’re also researching how to “recompose” photos, to create images that are more professional or creatively composed, even when shot on a smartphone. The organization and retrieval of images, Lin says, also has huge opportunities. How do you make sure the photos and memories captured on smartphones are not lost when people replace them throughout their lives? Or how do you sort thousands of photos of your kids? Lin is curious about what kind of software could enable you to tell a photo story from babyhood to college. “We are thinking about how to use AI to tell stories with your photos,” she says. “It can mine through collections, events, and digital archives, too.” BUSINESS OPPORTUNITIES FOR COMPUTER VISION Computer vision is a blue-sky area of research that many at HP and beyond see as ripe for innovation. At a basic level, it involves training computers with algorithms to replicate what human brains can do when they identify and interpret an image—but to do it with the speed of a machine and on a massive scale. Lin and her team are exploring several projects that apply computer vision to new business opportunities. One looks at how to build printers that can improve image quality. If you think about the printing process right now, it’s an open loop, explains Lin. Closing the loop would mean the printer itself can optimize images. “The printer can identify deviations, understand and ‘see’ what’s being printed, and make it perfect,” she says. In the broader ecosystem of HP, computer vision can potentially be applied to manufacturing printheads. Right now, it takes a small army of people to inspect each one. “This is tedious work being done by human operators with microscopes. It’s extremely repetitive,” Lin says. “So, how can we use deep-learning computer vision algorithms to inspect those products as they are being made, and make sure the quality passes our criteria?” PERSISTENCE AND PREDICTIONS Lin’s ability to develop new technologies over her career and create new opportunities in AI and deep learning is among the many reasons she’s been named an HP Fellow. “A Fellow needs to work across organizations, champion ideas, and push technology development,” she says. Lin says in the next decade HP will bring new tools and technologies to the marketplace, and she is excited to be part of it. “I see a lot of opportunities to apply AI and machine learning in our products,” she says. “There are so many things I’d like to see happen, and I have the privilege of leading people who share the same vision.” Dr. Lin is responsible for 45 filed patents and 21 pending patents so far in her 28 years at HP. 23
