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

Description: An extension of the non local (NL) means is proposed for
images damaged by Poisson noise. The proposed method is
guided by the noisy image and a pre-filtered image and is
adapted to the statistics of Poisson noise. The influence of
both images can be tuned using two filtering parameters. We
propose an automatic setting to select these parameters based
on the minimization of the estimated risk (mean square error).
This selection uses an estimator of the MSE for NL means
with Poisson noise and Newton’s method to find the optimal
parameters in few iterations(An extension of the non local (NL) means is proposed for images damaged by Poisson noise.)

的版权保护。(An adaptive watermark blind watermarking algorithm based on QR codes is proposed. Methods first of all, the carrier QR code is three levels smaller.
Wave transformation and 4 *4 block Schur decomposition of the low frequency part are carried out. Then the binary values are obtained by using the stability of the coefficient difference of the subblock unitary matrix.
The watermark information is embedded into the carrier QR code adaptively. Finally, the watermark information is extracted by scanning the watermark QR code. At the same time, the algorithm achieves blind extraction. Results The algorithm can resist the attack of print and scan, and can resist Gaussian noise, salt and pepper noise, speckle noise, Poisson noise.
JPEG attacks such as compression have strong robustness. Conclusion the algorithm has strong resistance to print scanning and can be widely used in digital products.
