However, the power spectrum of the non-degraded image is seldom known, and the constant k is used to estimate it.So the disadvantage of wiener filtering is that The power spectrum of the non-degraded image and noise must be known; The estimation of the power ratio (signal-to-noise ratio ) constant K is generally

The scaling of digital images is a very interesting problem, but also a seemingly simple, but some complex problems. Many friends after having a certain basic knowledge of computer graphics programming, they can design some simple bitmap scaling algorithm. In the field of computer graphics and digital image processing, the problem of
