Project Title:
WaveLens: Real-Time Video Frequency Spectrum Visualizer
Synopsis:
WaveLens is a cutting-edge, browser-compatible web application that captures live video from a user’s camera and transforms it into a dynamic frequency spectrum visualization. Merging real-time image processing with frequency analysis, this tool offers an innovative way to explore the hidden vibrational patterns within visual input. The application will leverage techniques like grayscale conversion and Fast Fourier Transform (FFT) to extract frequency data from each frame and render an evolving, interactive visualization that reflects the underlying harmonic content.
This project stands at the intersection of art, science, and technology, turning video data into a live signal-processing canvas. Whether used for educational insight, artistic expression, or experimental research, WaveLens opens a new perceptual portal into the energetic structure of moving imagery.
n addition to frequency analysis, the app will include a light mapping feature that captures and visualizes subtle variations in brightness and luminance across video frames. By translating light intensity data into spatial heatmaps or wave patterns, this tool reveals hidden structures in the light field, offering users a new dimension of perception. This capability not only enhances the visual richness of the spectrum display but also opens possibilities for analyzing coherence, motion, and even symbolic light signatures in real-time environments.
Core Features:
- Live Camera Feed Integration
- Access user’s webcam in real time via browser.
- Real-Time Frame Processing
