Digital Image Processing Lecture(3) 2024/6/9
In this video, we try to explain about Stochastic charactrization of digital images. First, we defined joint probability density fuction, then continuing the following items:The Gaussian density, the Rayleigh density, the exponential density, the first moment or mean of the image function, the second moment or autocorrelation function, the autocovariance, stationary in the strict sense, stationary in the wide sense, the power spectral density, the probability density of the output image, the relationship between the power spectra of the input and output image, etc.
