//! Scene and content classification.
//!
//! This module provides various classification algorithms for video frames:
//!
//! - **Scene classification**: Indoor/outdoor, day/night, landscape/portrait
//! - **Content classification**: Sports, news, drama, action
//! - **Quality classification**: Sharp/blurry, noisy, technical quality
//! - **Mood analysis**: Brightness, warmth, contrast, saturation
//! - **Shot type**: Close-up, medium, wide, establishing
//! - **Color palette**: Dominant colors via k-means
