ROI Tracker

ROI Tracker is an ROI (Region of Interest) based motion analysis and measurement app for iPhone or iPad. Using camera image analysis, ROI Tracker visualizes motion inside a selected ROI and analyzes speed, rotation (RPM), vibration frequency, and motion characteristics. Key Features: • Motion Speed Measurement Analyze movement speed from pixel displacement tracking inside the ROI. • Rotation Analysis (RPM) Detect periodic motion and rotational behavior to visualize RPM. • Vibration Analysis Analyze vibration frequency and vibration characteristics from micro pixel displacement. • ROI Tracking Track selected regions for image-based motion analysis. • Trend Graph Logging Record measurement history and visualize changes over time. • FFT Frequency Analysis Visualize frequency components and analyze vibration and periodic motion using FFT analysis. • High Frame Rate Support Compatible with high frame rate camera capture for fast motion analysis. • On-Device Processing All analysis is processed locally on your device. No image or measurement data is transmitted to external servers. ROI Tracker can be used for engineering, research, equipment maintenance, maker projects, motion visualization, video analysis, education, experimentation, and even casual exploration.
