Consider the dependencies between the coefficients and their parents, a non-Gaussian bivariate distribution is given, and corresponding nonlinear threshold function is derived from the model using Bayesian estimation theory. According to non-subsampled Contourlet transform and bivariate threshold function, a novel Non-Subsampled Contourlet Transform based on Bivariate threshold function for image denoising is proposed. This scheme achieves enhanced estimation results for images that are corrupted with additive Gaussian noise over a wide range of noise variance.

Result The background noise of bidirectional electrophoresis map of protein extracted by TCAJA method was greater, its clarity was poor, its horizontal striations were more and there were tinny spots with irregular shape appeared on it. The variegated spots had difference from the normal protein spots, they formed high coverage and shading on the other protein spots and affected the accurate expression of map information. The background noise of bidirectional electrophoresis map of protein extracted by Trizol method was little, its horizontal striations and non-protein impurities were less, there was no shading phenomenon strong spots and mere protein spots, so it provided abundant information for quantitative and qualitative analyses on the proteome from buffalo grass seeds, Compared with TCA/A precipitation.
