- Figure 2: Block diagram of multiscale denoising. The noisy photographic image is first decomposed into a multiscale representation. The noisy pyramid coefficients, y, are then denoised using the functions, ˆx(y), resulting in denoised coefficients, ˆx. Finally, the pyramid of denoised coefficients used to reconstruct the denoised image. pixels.

- CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Signal acquisition is a noisy business. In photographic images, there is noise within the light intensity signal (e.g., photon noise), and additional noise can arise within the sensor (e.g., thermal noise in a CMOS chip), as well as in subsequent processing (e.g., quantization).

- Arguably several thousands papers are dedicated to image denoising. Most papers assume a fixed noise model, mainly white Gaussian or Poissonian. This assumption is only valid for raw images. Yet, in most images handled by the public and even by scientists, the noise model is imperfectly known or unknown. End users only dispose the result of a complex image …
