Image Watermarking Using Spatial Domain

Abstract

Watermarking is the most imperative innovation for installing (Adding) concealed picture into the information picture with the assistance of different calculations. Due to this feature of watermarking now days it is gaining lot of attraction. Now a day for preventing duplication an image is embedded in the information. In various applications such as Digital audio, video, and images a hidden copyright images is inserted into the original data. In this paper for inserting computerized watermark into the objective picture an anchored procedure is proposed. The proposed calculation will perform imperceptible watermarking of picture in spatial space. The Key is embedded in the original image and it will transfer to the receiver. At the receiver end the key is extracted using proposed algorithm. Various observationsare done on the image like peak signal to mean noise ratio (PSNR).PSNR is comes out to bethe Peak-SNR value is 20.4082, The Signal to Noise ratio (SNR) value is 14.8358 for the Gaussian noise for zero mean and 0.01 variance.
The Peak-SNR value is 18.9910, The SNR value is 13.4185 for the salt and pepperfor0.04 correlation coefficient.
