A Benchmark for Sparse Coding: When Group Sparsity Meets Rank Minimization
Zhiyuan Zha, Xin Yuan, Bihan Wen +3
Sparse coding has achieved a great success in various image processing tasks. However, a benchmark to measure the sparsity of image patch/group is missing since sparse coding is es…
Image Compression Based on Compressive Sensing: End-to-End Comparison with JPEG
Xin Yuan, Raziel Haimi-Cohen
We present an end-to-end image compression system based on compressive sensing. The presented system integrates the conventional scheme of compressive sampling and reconstruction w…
Block-wise Lensless Compressive Camera
Xin Yuan, Gang Huang, Hong Jiang +1
The existing lensless compressive camera ()~\cite{Huang13ICIP} suffers from low capture rates, resulting in low resolution images when acquired over a short t…
Compressive Sensing via Convolutional Factor Analysis
Xin Yuan, Yunchen Pu, Lawrence Carin
We solve the compressive sensing problem via convolutional factor analysis, where the convolutional dictionaries are learned {\em in situ} from the compressed measurements. An alte…
