Web4.2.1 Salt and pepper noise. Salt and pepper noise, also known as data drop-out, can cause pointed and unanticipated disturbances in the image signal. The noise density here is 0.01. The images distorted by this noise and the watermarks extracted from them are shown in Fig. 10 for standard images and medical images. WebIn digital communication or data transmission, ( energy per bit to noise power spectral density ratio) is a normalized signal-to-noise ratio (SNR) measure, also known as the "SNR per bit". It is especially useful when comparing the bit error rate (BER) performance of different digital modulation schemes without taking bandwidth into account.
