Poisson noise adalah
Shot noise or Poisson noise is a type of noise which can be modeled by a Poisson process. In electronics shot noise originates from the discrete nature of electric charge. Shot noise also occurs in photon counting in optical devices, where shot noise is associated with the particle nature of light. See more In a statistical experiment such as tossing a fair coin and counting the occurrences of heads and tails, the numbers of heads and tails after many throws will differ by only a tiny percentage, while after only a few throws outcomes … See more Electronic devices Shot noise in electronic circuits consists of random fluctuations of DC current, which is due to electric current being the flow of discrete charges (electrons). Because the electron has such a tiny charge, however, shot noise is of … See more • Johnson–Nyquist noise or thermal noise • 1/f noise • Burst noise See more WebSep 10, 2011 · Noise didefinisikan sebagai suara bising yang dihasilkan dari getaran nonperiodik diudara atau secara lebih umum dapat didefinisikan sebagai suara yang tidak diinginkan.

WebNow I want to add Poisson noise to the sinogram before applying the inverse radon transform. For the reconstruction, the paper I'm following suggests to replace the data-fidelity term in ${min}_x \frac{1}{2} Hx-y ^2_2$ with weighted least squares. (Here, x is the input image and y is what we are measuring).
