摘要：The growing need to protect the digital media fromunauthorized access results into the development of differentwatermarking techniques. The choice of a good watermarkingtechnique leads to the best watermarking process. In thispaper watermarking process is performed by taken a hybridtechnique which consists of three different techniques offrequency domain. The quality of the watermarked images isenhanced by following a hybrid technique with Kalmanfiltering. Singular value decomposition, discrete wavelettransform and discrete cosine transform along with KalmanFiltering are used as a hybrid technique to protect the imagefrom unauthorized attacks. The obtained watermarked imageis then going through various image processing attacks. Theresults have shown that the hybrid technique gives acceptablevalues against these attacks.
