How Kuvatilaus.fi and Silo AI use the latest methods in computer vision for flawless image matting
Imagine you have a studio photo that you would want to blend on a different background. You open your photo editing tool, and use, depending on your skills, countless minutes or hours to individually do this to all your photos.
Now imagine you do this with help of the latest deep learning methods in computer vision that analyze every pixel so that not a single hair is missed. In the fully customized solution built in collaboration by Kuvatilaus.fi and Silo AI, you simply upload your photos, and in a matter of seconds, the AI technologies take care of meticulously removing the background.
Leveraging the latest deep learning methods in computer vision
Tuuli Mankki, Service Manager at Kuvatilaus.fi, wanted to offer their clients an AI solution with unmatched quality to help them with a daily and time consuming task of removing the background:
“We wanted professional photographers to have access to a high quality matting tool that would work flawlessly even with challenging details and high resolution images, such as 4K photographs. In Silo AI, we found an experienced partner with which it was possible to create a tailored AI solution that perfectly fits our needs and exceeds all our expectations.”, Mankki comments.
Deep learning to do image matting of 4K images in a matter of seconds
The first step in background removal is to use AI to create a trimap to separate foreground from background. Then, computer vision technologies are used to select the foreground and eventually blend it on the desired new background.
4K images, pixel perfection and fast performance – around 10 seconds – posed a challenge for Silo AI’s AI Scientist Mikko Tukiainen and his team. To solve it, the team needed to leverage several tricks in data processing and a clever solution design to optimize the neural net.
“It was great to collaborate with Kuvatilaus.fi on a challenging project that required a lot of customization. Luckily, they gave us over 50 thousand example studio quality portraits to train the AI solution, and with sophisticated techniques such as data augmentation, we were able to make the AI solution robust, fast and working with top-notch quality.” Tukiainen comments.
Tukiainen compared the AI solution with 100+ test images with other background removal solutions out there.
“In order to match the desired precision level, we needed to process and augment artificial images used in training with features like vignette or tilt shift blur as well as noise augmentation. As a result the matting tool provided by Kuvatilaus.fi now has the best performance on the market.”
