An AI-based Nature Camera app that combines real-time preview, ML-based subject segmentation, and a set of portrait-style effects Invert, Swirl, Zoom Burst, Duotone, Phantom, and more. It also uses background processing so photos continue saving even if the app is closed. The biggest lesson here wasn't about features, it was about understanding exactly where every millisecond and megabyte was going.
Engineering Optimizations
- Resolution-Aware Processing - Matched the ML and effect layers to the necessary output scale.
- Memory Management - Drastically reduced unnecessary memory copies between the JVM and native layers.
- Math Optimization - Refined blur and pixel operations to run more efficiently across the processing pipeline.
