Visual Rhetoric & Composition Analyzer

An interactive computational tool designed for visual social science, media framing analysis, political communication, and digital humanities to audit visual bias, compositional structures, and dominant color palettes.

Features

  1. Interactive K-Means Palettes: Automatically clusters image pixels to extract the top 5 dominant colors with complete visual psychology and framing interpretations.
  2. Rule-of-Thirds Composition Overlay: Draws vertical and horizontal grid lines, highlights focal power intersections, and calculates visual center-of-gravity weights using Canny edges.
  3. Luminance & Contrast Histograms: Plots image brightness curves and mathematically classifies the image's lighting style (e.g., High-Key, Low-Key, or Mid-Key standard).
  4. Instant Local Computation: Runs entirely locally using OpenCV, NumPy, and Scikit-Learn for ultra-fast, zero-overhead computation that starts up immediately on basic CPU hardware.
