The Perona-Malik (PM) model is used successfully in image processing to eliminate noise while preserving edges; however, this model has a major drawback: it tends to make the image look blocky. A shrinkage (mapping) function is directly modeled as a linear combination of radial basis function kernels, where is the shared precision parameter, denotes the (equidistant) kernel positions, and M is the number of Gaussian kernels. Undecimated Wavelet Transform (UDWT) - a shift invariant technique, used for decomposing the signal to provide visually better solution. Where a = (m - 1) / 2, b = (n - 1) / 2.The process, which is opposite to convolution, is called deconvolution and solution of such task is quite uncommon. application a la restauration de films cinematographiques". 3. 12.
