Image Restoration: Noise Models: Transcript

By Dr Rajeev Srivastava Principle Sources of Noise Noise Model Assumptions When the Fourier Spectrum of noise is constant the noise is called White Noise The terminology comes from the fact that the white light contains nearly all frequencies in the visible spectrum in equal proportions . hujiacil Yair Weiss School of Computer Science and Engineering Hebrew University of Jerusalem httpwwwcshujiacilyweiss Abstract Learning good image priors is of utmost importance for the study of vision computer vision and image processing application Lecture 21: Image Restoration.
