Hi everone!
I wanted to add gaussian noise to an image. I used the command like noisy=imnoise (image, 'gaussian', 0, 0.05), it makes the image so noisy. In different Journal papers different researchers are claiming that they are adding gaussian noise with the power such as 20dB, 25dB etc. moreover their reported images are also in good quality. I am unable to solve this mystery, as this command gives some floating type result but not as a whole number. I am also attaching the published papers. Please anyone have a look on them and reply, Thanks.
