Video Signal Processing
Current status
• Algorithm
– Improved shot-noise detection with up to 17%
• Implications Manages mechanical damages better
Reduces artefacts from block- or frame loss One paper published
– Algorithm refinement and its implication on implementation cost
• Same performance @ no cost in terms of area and timing for ASIC impl.
• Manages real times performance for FPGA-technology
• Same implementation costs for both algorithms.
• One paper published
