Prisma is a photo-editing application that utilizes a neural network and artificial intelligence to transform the image into an artistic effect.
The app was created by Alexey Moiseenkov (Russian: ??????? ??????????), Oleg Poyaganov, Ilya Frolov, Andrey Usoltsev and it was launched in June 2016 as a free mobile app. A week after its launch, the app gained popularity and received over 7.5 million downloads and over 1 million active users as of July 2016. It debuted on iOS on Apple App Store during the first week of June and it became the leading app at the App Store in Russia and other neighboring countries. On 19 July 2016, the developer launched a beta version of the app for Android and it closed few hours later by developers after receiving feedback from its users. It was later released publicly on 24 July 2016 on Google Play.
In July 2016, the developer announced that the video and virtual reality version of the app is currently under development.
On July 7, 2017, Prisma launched a new app called Sticky which turns selfies into stickers for sharing to your social feeds.
Maps, Directions, and Place Reviews
The app was created by the team led by Alexey Moiseenkov who also founded the Prisma labs, based in Moscow. Moiseenkov previously worked at Mail.Ru and later resigned from his job to dedicate his time for the development of the app. He said that the development of the app took only one and a half months and the team did not do anything to promote the app.
The algorithm that powers the app is based on the open source programming and algorithms behind DeepArt.
App That Turns Pictures Into Paintings Video
Users can upload pictures and select a variety of filters to transform the picture into an artistic effect. At launch, the app offered twenty different filters. Additional filters are added daily. In July 2016, Moiseenkov stated that the app will offer forty filters by the end of the month.
The image rendering takes place in Prisma labs's servers and it uses a neural network and artificial intelligence to add the artistic effect. The result is delivered back to the user's phone. Unlike other photo editing apps, Prisma renders the image by going through different layers and recreating the image rather than inserting a layer over the image.
In August 2016, the iOS version of the app was updated to edit image offline by utilizing the phone's processor for image rendering.
One week after its debut on iOS App Store, the app was downloaded over 7.5 million times and received over 1 million active users. It also became the top listed app in Russia and its neighboring countries. In the end of July 2016, it was installed over 12.5 million devices with over 1.5 million active users worldwide. According to App Annie, it was listed in the top 10 apps on the App Store in 77 different countries.
On the first day of the Android version release, it received over 1.7 million downloads with 50 million pictures processed by the app.
Research and technology
The research paper behind the Prisma App technology is called "A Neural Algorithm of Artistic Style" by Leon Gatys, Alexander Ecker and Matthias Bethge and was presented at the premier machine learning conference: Neural Information Processing Systems (NIPS) in 2015. This technology was developed independently and before Prisma, and both the university and the company have no affiliation with one another.
Further recent work developed by Stanford University: Perceptual Losses for Real-Time Style Transfer and Super-Resolution by Justin Johnson, Alexandre Alahi and Li Fei-Fei has also been able to create real-time style transfer through video.
The code for the previous papers is available at no charge at GitHub for research purposes. The Prisma App (on the industrial front), and Style Transfer and Super Resolution (on the research front) has been made possible thanks to research and development in human perception, texture analysis, convolutional neural networks.
