Digital Detail Enhancement (DDE)

Overview

Developed algorithms to enhance fine details and edges in images while minimizing noise amplification.

Responsibilities

• Designed edge enhancement filters
• Balanced sharpness vs noise trade-offs
• Tuned parameters for different imaging conditions

Approach

• High-frequency boosting
• Edge-aware filtering
• Adaptive enhancement strength
