Description: 当前论文主要考虑的是非信号依赖的高斯噪声下的图像恢复，本程序实现了泊松噪声下的图像恢复，泊松噪声为信号依赖噪声，能够更加有效逼近实际成像系统噪声。- This is the code that was used in the papers "A Nonnnegatively Constrained Convex Programming Method for Image Reconstruction", "Total Variation-Penalized Poisson Likelihood Estimation for Ill-Posed Problems", "Tikhonov Regularized Poisson Likelihood Estimation: Theoretical Justification and a Computational Method", "An Efficient Computational Method for Total Variation with Poisson Negative-Log Likelihood", "An Analysis of Regularization by Diffusion for Ill-Posed Poisson Likelihood Estimation," "An Iterative Method for Edge-Preserving MAP Estimation when Data-Noise is Poisson", and finally, "Regularization Parameter Selection Methods for Ill-Posed Poisson Maximum Likelihood Estimation". See my publications page for more details. The main algorithm is for nonnegatively constrained, regularized Poisson likelihood estimation. At this point you can choose Tikhonov, total variation regularization, and diffusion regularization. A number of other methods are also implemented. Regularizatio Platform: |

Description: We propose a generalized equation to represent a continuum of surface
reconstruction solutions of a given non-integrable gradient field. We show
that common approaches such as Poisson solver and Frankot-Chellappa algorithm
are special cases of this generalized equation. Platform: |

Description: Poisson surface reconstruction creates watertight surfaces from oriented
point sets. In this work we extend the technique to explicitly incorporate
the points as interpolation constraints. The extension can be interpreted as
a generalization of the underlying mathematical framework to a screened
Poisson equation. In contrast to other image and geometry processing
techniques, the screening term is defined over a sparse set of points rather
than over the full domain. We show that these sparse constraints can
nonetheless be integrated efficiently. Because the modified linear system
retains the same finite-element discretization, the sparsity structure is
unchanged, and the system can still be solved using a multigrid approach.
Moreover we present several algorithmic improvements that together
reduce the time complexity of the solver to linear in the number of points,
thereby enabling faster, higher-quality surface reconstructions. Platform: |
