查询词典 statistical decision process

Based on the method of restoring the image by estimating the camera shake trace which is proposed by Fergus in 2006 as reference, we find the difference of statistical characteristics between blurred images and latent images by exploiting the natural image statistical characteristics more deeply, i.e. the precise components of natural clear images obey the Laplace distribution in their wavelet domain, but blurred images dont have this kind of characteristic.

With the wide development of the mixed Poisson distribution in the medical, financial and insurance applications, it is receiving increasing attention. But, according to the author to understand, at present, studies on the Mixed Poisson distribution of the literature are relatively small, the most important reason is that it does not have a Mixed Gaussian distribution of a wide range of applications. However, with advances in computer technology and the development of statistical techniques, Mixed Poisson distribution analysis of statistical data will play an increasingly important role, thus the system in detail study of Mixed Poisson distribution model parameter estimation is necessary.
