In this study, a novel noise reduction algorithm for hyperspectral imagery (HSI) is proposed based on high-order rank-1 tensor decomposition. The hyperspectral data cube is considered as a three-order tensor tha
In order to detect noise efficiently a better detection and reduction process is used which gives better results. In this paper, a new algorithm is presented to improve the performance of other filters. This method consists of two stages: initially the detection stage will detect the noisy ...
CNN’s two characteristics, sparse connection, and weight sharing explain why it has become the most popular deep learning algorithm. For images, product NN has a strong learning ability. It is commonly used as the network infrastructure for image classification. ialexnet, VGg, inception, and ...
Therefore, the image had to be processed using structure preserving noise reduction. Pixel values were related to printing material thickness to result in a similar attenuation pattern as the original patient including support mattress. A 3D model generating a similar x-ray attenuation pattern on an...
Improving the quality of medical images is crucial for accurate clinical diagnosis; however, medical images are often disrupted by various types of noise, posing challenges to the reliability and diagnostic accuracy of the images. This study aims to enha

PureImage will automatically auto-tune the noise function to different noise type across the image, making the interface much simpler and universal for all digital or film cameras. There are few Advanced Processing presets for better tuning the NR algorithm ...
We then develop an efficient ADMM algorithm for solving the proposed model. In Section 4 we evaluate our approach by comparing with the state of the art in simulated and real HSI dataset. Finally, conclusions are drawn in Section 5.Access through your organization Check access to the full ...

Though any denoising algorithm can be used in our proposed scheme, here we apply spatial similarity combined with transform domain image patch group-sparsity as our regularizer [39], to form the regularized iterative SR problem as an example. Similar to the method in Sect. 4.1.5.2, we ...
