VitamotusMobile app to let users stream their camera image with semantic segmentation (background removal). Image broadcasts to Unreal Engine scene via various backend services and lets people take part in virtual concert / event. Also users can record their own avatars, edit them and send to Unreal Engine in sprite sheet format.• I made an app from scratch. Implemented video streaming from device to backend using RTMP protocol(changed later to SRT protocol to improve performance and reduce the delay).• Researched best ways to achieve real-time background replacement even on old devices. Implemented semantic segmentation using TFLite and DeepLabV3 models that I retrained on my own dataset. As a result, it was possible to achieve 25 fps on a weak devices(iPhone 6) while streaming.• To improve quality of segmentation I implemented another version using ARKit3 with People Occlusion feature and Metal shaders. This allowed us to achieve a perfect quality background cut-out.• Met and solved many problems, such as device heating, increased battery use, memory leaks.• I also implemented feature of recording, saving and editing user’s animation avatar. With the help of SpriteKit I made 8x8 sprite sheet to easily transfer it to Unreal Engine scene as png file.Technologies: Swift, Alamofire, AVFoundation, ARKit, CoreImage, SpriteKit, Metal, AWS Cognito, CoreData, TFLite (model retraining), socketsBinovi ProAn app for Optometrists and Vision Care professionals.
