Texture synthesis based on wavelet transform

Texture synthesis is an important process in image post-production. A Large number of previous approaches can be classified as either parametric or nonparametric method. Of these, the nonparametric approaches have achieved the most impressive results. This paper proposes a fast and efficient algorithm of texture synthesis algorithm; it is based on patch-based texture synthesis algorithm. We propose a pyramid-based synthesis algorithm. First, we apply wavelet to analysis texture figure. At the same time, we save the details of every level. And use the low-resolution to reconstruct the high-resolution texture by the inverse wavelet transform, and add the details to the results. In the paper, we will analysis some typical algorithm, and take an an experiment on it, then we will propose an improved algorithm and compare it with some typical algorithms.
