—Most of the rules relating simple nonlinear threshold values for wavelet-based de-noising have assumptions that the wavelet coefficients are independent values. However, when we talk of natural images, we observe that wavelet coefficients have significant dependency. The phrase Peak Signal to Noise Ratio, often abbreviated PSNR, is an [9] engineering term for the ratio between the maximum possible power of a signal and the power of corrupted noise that affects the fidelity of its… CONTINUE READING
