Rayleigh density function
WebJan 12, 2024 · We can generate Rayleigh noise on images by using Rayleigh probability density function. Some authors have also named it probability distribution function. We already described the process of adding Gaussian noise to images. Similarly, we distribute Rayleigh noise values with a probability distribution function.

WebThe other calculation is very similar. Let X be Rayleigh with parameter σ 2. Then X has density function x σ 2 e − x 2 / ( 2 σ 2) for x ≥ 0, and 0 elsewhere. Let Y = X 2. We find the density function f Y ( y) of Y. To do this, we first find the cdf F Y ( y) of Y. For y > 0, we have. F Y ( y) = Pr ( Y ≤ y) = Pr ( X 2 ≤ y) = Pr ( X ≤ ...
