FRESH – FRI-based single-image super-resolution algorithm [PDF]
, 2016 In this paper, we consider the problem of single image super-resolution and propose a novel algorithm that outperforms state-of-the-art methods without the need of learning patches pairs from external data sets.

CW-SSIM based image classification [PDF]
2011 18th IEEE International Conference on Image Processing, 2011 Complex wavelet structural similarity (CW-SSIM) index has been proposed as a promising image similarity measure that is robust to small geometric distortions such as translation, scaling and rotation of images, but how to make the best use of it in image classification problems has not been deeply investigated.

Zhejiang Daxue xuebao. Lixue ban, 2018 互联网的飞速发展，产生了大量的图像信息.为了减少图片占用的存储空间，提高图像质量，提出了一种将主成分分析(PCA)和分层树集合划分(SPIHT)压缩算法相结合的有损图像压缩算法.首先对图像进行主成分分解，选取主要特征值进行压缩，再利用SPIHT算法将图像分解成不同子带的小波系数进行压缩，对SPIHT压缩系数进行哈夫曼编码，实现图像二级压缩.将本文提出的算法与SPIHT、SPIHT的哈夫曼编码、JEPG2000、PCA压缩算法进行了比较，结果表明本算法较其他压缩算法具有更好的性能 ...

Simulation of Scour at Bridge Supports
Građevinar, 2020 Groups of piers are used on bridges to minimise scour around bridge supports. The prediction of scour around piers due to interaction of vortices around bridge piers is more complex compared to scour prediction around a single pier.

Merger as Intermittent Accretion
, 2008 The Self-Similar Secondary Infall Model (SSIM) is modified to simulate a merger event. The model encompass spherical versions of tidal stripping and dynamical friction that agrees with the Syer & White merger paradigm's behaviour.

Optimizing Multiscale SSIM for Compression via MLDS [PDF]
IEEE Transactions on Image Processing, 2012 A crucial step in the assessment of an image compression method is the evaluation of the perceived quality of the compressed images. Typically, researchers ask observers to rate perceived image quality directly and use these rating measures, averaged across observers and images, to assess how image quality degrades with increasing compression.

A Transfer-Learning Approach for Accelerated MRI using Deep Neural Networks
, 2019 Purpose: Neural networks have received recent interest for reconstruction of undersampled MR acquisitions. Ideally network performance should be optimized by drawing the training and testing data from the same domain. In practice, however, large datasets
