Qualitative and Quantitative Perspectives on Video Watermarking Approaches
Vaishali Kalra, Chirag Sharma · 2025
The technique of video watermarking performs a critical part in ensuring protection of digital video content by embedding an imperceptible yet detectable mark into the video stream. This paper explores both the qualitative and quantitative aspects of various video watermarking techniques. The study categorizes watermarking methods into spatial domain and frequency domain techniques, providing a comprehensive comparison of their effectiveness regarding visual being imperceptible and resilient to attacks, computational complexity, along with embedding capacity. Important quantitative evaluation measures are provided, such as PSNR(Peak Signal to Noise Ratio), Bit Error Rate(BER), and Structural Similarity Index(SSIM).
