Overview
Transformed an existing idea into a fully functional mobile app that enables users to preview and apply real-time camera filters inspired by seasonal color palettes (Spring, Summer, Autumn, Winter). Led the entire development process from technical planning to implementation.
Problem & Objective
Build a lightweight and responsive filter system for real-time image processing on mid-range Android devices. The app needed to accurately apply seasonal color tones while maintaining smooth performance and user interactivity.
My Contribution
- Designed a modular architecture in Flutter separating camera preview, filter application, and UI
- Built a custom, lightweight image filter pipeline that performs real-time color transformations
- Optimized performance with platform-specific enhancements to avoid frame drops and latency
Features
- Real-time camera preview with seasonal filters
- Four seasonal color palettes (Spring, Summer, Autumn, Winter)
- Instant filter application and comparison mode
- Photo capture with applied filters
- Gallery integration for existing photos
- Optimized for mid-range Android devices
- Custom lightweight image processing pipeline
Challenges
Ensuring smooth 30fps performance on mid-range Android devices required careful optimization of the image processing pipeline. Implemented custom shaders and platform-specific enhancements for real-time filtering.
Outcome
Improved user engagement by 40% during testing phase. Ensured stable performance on mid-range Android devices. Successfully launched on Google Play Store.
