High-Performance Stroboscopic Action Sequence Camera for Android
Engineered and maintained by Ahmad Hassan (B-Ted)
Human movement is inherently transient. Whether an athlete sprinting, a dancer executing a spin, a gymnast mid-air, or a child jumping, fleeting physical motion unfolds and vanishes within fractions of a second.
MotionShot bridges high-speed mobile computer vision with human kinetic expression. Inspired by Sony's legacy Motion Shot technology, MotionShot captures dynamic action bursts and synthesizes a single, multi-pose stroboscopic composite image directly on-device in real time.
Operating entirely offline with zero cloud latency and zero reliance on heavy AI neural networks, MotionShot renders motion as an aligned visual trajectory: sharp, stabilized, and captured in full sensor resolution.

Pixel-to-Pixel Handheld Image Stabilization: The 2D translation alignment engine (
ImageStabilizer) correlates background grid pixels across frames, locking static elements in place to eliminate camera shake. - Normalized Chromaticity Motion Differencing: Evaluates $r, g$ color space ratios alongside BT.601 luminance separation, making motion detection 100% immune to camera exposure shifts and shadows.
