A Robust Wavelet Based Watermarking System for Color Video
In this paper, we propose a wavelet based watermarking system. The system use wavelet transform for red, green and blues channel independently. We use space-time coding for encoding the watermark message before data embedding. The bit-error-rate of recovered message is calculated. The embedding fa...

| description | In this paper, we propose a wavelet based watermarking system. The system use wavelet transform for red, green and blues channel independently. We use space-time coding for encoding the watermark message before data embedding. The bit-error-rate of recovered message is calculated. The embedding factor is selected in such a way that the host video maintains the same peak signal to noise ration with/without using space-time coding. The developed system is further examined, when host video faces compression and noise addition. Result shows the effectiveness of proposed watermarking system, especially when space-time coding is used.äºå¯é çåºæ¼å°æ³¢è®æçæ¸åæ°´å°ç³»çµ±ç彩è²è¦é »æè¦å¨æ¬æä¸ï¼æåæåºäºä¸ç¨®åºæ¼å°æ³¢è®ææ°´å°ç³»çµ±ã該系統使ç¨å°æ³¢ç¨ç«å°è®æçºç´
