In medical contexts, computed tomography (CT) plays a crucial role in reconstructing a patient's internal structure, presenting challenges due to artifacts caused by inherently ill-posed inverse problems. Previous research advanced image quality via post-processing and deep unrolling algorithms but faces challenges, such as extended convergence times with ultra-sparse data. Despite enhancements, resulting images often show significant artifacts, limiting their effectiveness for real-world diagnostic applications. We aim to explore deep second-order unrolling algorithms for solving imaging inverse problems, emphasizing their faster convergence and lower time complexity compared to common first-order methods like gradient descent. In this paper, we introduce QN-Mixer, an algorithm based on the quasi-Newton approach. We use learned parameters through the BFGS algorithm and introduce Incept-Mixer, an efficient neural architecture that serves as a non-local regularization term, capturing long-range dependencies within images. To address the computational demands typically associated with quasi-Newton algorithms that require full Hessian matrix computations, we present a memory-efficient alternative. Our approach intelligently downsamples gradient information, significantly reducing computational requirements while maintaining performance. The approach is validated through experiments on the sparse-view CT problem, involving various datasets and scanning protocols, and is compared with post-processing and deep unrolling state-of-the-art approaches. Our method outperforms existing approaches and achieves state-of-the-art performance in terms of SSIM and PSNR, all while reducing the number of unrolling iterations required. +# Citation -## Start using the template -To start using the template click on `Use this Template`. +Please cite our paper if you find it useful for your research. -The template uses html for controlling the content and css for controlling the style. -To edit the websites contents edit the `index.html` file. It contains different HTML "building blocks", use whichever ones you need and comment out the rest. - -**IMPORTANT!** Make sure to replace the `favicon.ico` under `static/images/` with one of your own, otherwise your favicon is going to be a dreambooth image of me. - -## Components -- Teaser video -- Images Carousel -- Youtube embedding -- Video Carousel -- PDF Poster -- Bibtex citation - -## Tips: -- The `index.html` file contains comments instructing you what to replace, you should follow these comments. -- The `meta` tags in the `index.html` file are used to provide metadata about your paper -(e.g. helping search engine index the website, showing a preview image when sharing the website, etc.) -- The resolution of images and videos can usually be around 1920-2048, there rarely a need for better resolution that take longer to load. -- All the images and videos you use should be compressed to allow for fast loading of the website (and thus better indexing by search engines). For images, you can use [TinyPNG](https://tinypng.com), for videos you can need to find the tradeoff between size and quality. -- When using large video files (larger than 10MB), it's better to use youtube for hosting the video as serving the video from the website can take time. -- Using a tracker can help you analyze the traffic and see where users came from. [statcounter](https://statcounter.com) is a free, easy to use tracker that takes under 5 minutes to set up. -- This project page can also be made into a github pages website. -- Replace the favicon to one of your choosing (the default one is of the Hebrew University). -- Suggestions, improvements and comments are welcome, simply open an issue or contact me.
