//! # Enhanced Advanced Mode Demonstration
//!
//! This example demonstrates the enhanced Advanced mode with comprehensive
//! validation, performance monitoring, and quality assessment capabilities.
//!
//! ## Features Demonstrated
//! - Enhanced Advanced processing with validation
//! - Real-time performance monitoring
//! - Quality assessment and reporting
//! - Error handling and robustness testing
//! - Benchmark collection and analysis

// Note: This example is under development. The enhanced_validation and fusion_core
// modules are not yet implemented in scirs2_ndimage.
