Privacy region protection for H.264/AVC with enhanced scrambling effect and a low bitrate overhead
作者：
Highlights：
• A detailed review of previous work in privacy protection for video surveillance.
• The combination of IPM and SNC to enhance the scrambling effect in privacy region.
• A re-encoding method to remove the drift error caused by the encryption of IPM.
• Experimental results in higher resolution videos are provided.
• A spiral binary mask to more efficiently indicate the position of privacy region.
