Introduction
• Restoration of old film
• using ACE (Automatic Equilization Algorithm)
• Form and implement extension
• Experiment and quality analysis
Film restoration
• Old, faded films
• Cannot be restored chemically
• Highly automated digital restoration algortithm wanted
Color correction algorithms
• Algortihms mimic some properties of the HVS to improve images
• Global
• Retinex, global/local WP algorithm
ACE
• My contribution:
• Inter-frame considersation
• Non-linear mapping function to avoid edges in the image
