Correlation Preserving Sparse Coding Over Multi-level Dictionaries for Image Denoising
Rui Chen, Huizhu Jia, Xiaodong Xie +1
In this letter, we propose a novel image denoising method based on correlation preserving sparse coding. Because the instable and unreliable correlations among basis set can limit…
Blind restoration for non-uniform aerial images using non-local Retinex model and shearlet-based higher-order regularization
Rui Chen, Huizhu Jia, Xiaodong Xie +1
Aerial images are often degraded by space-varying motion blur and simultaneous uneven illumination. To recover high-quality aerial image from its non-uniform version, we propose a…
An Attention-Driven Approach of No-Reference Image Quality Assessment
Diqi Chen, Yizhou Wang, Tianfu Wu +1
In this paper, we present a novel method of no-reference image quality assessment (NR-IQA), which is to predict the perceptual quality score of a given image without using any refe…
Globally Variance-Constrained Sparse Representation and Its Application in Image Set Coding
Xiang Zhang, Jiarui Sun, Siwei Ma +4
Sparse representation leads to an efficient way to approximately recover a signal by the linear composition of a few bases from a learnt dictionary, based on which various successf…
Face Detection with End-to-End Integration of a ConvNet and a 3D Model
Yunzhu Li, Benyuan Sun, Tianfu Wu +1
This paper presents a method for face detection in the wild, which integrates a ConvNet and a 3D mean face model in an end-to-end multi-task discriminative learning framework. The…
Maximal Sparsity with Deep Networks?
Bo Xin, Yizhou Wang, Wen Gao +1
The iterations of many sparse estimation algorithms are comprised of a fixed linear filter cascaded with a thresholding nonlinearity, which collectively resemble a typical neural n…
