Noisy practical facial super-resolution method via deformable constrained model with small dataset
Face Super-Resolution (FSR) is to infer high resolution facial image(s) from given low resolution one(s). But when large-scale training samples are absent, FSR may fail in inferring high resolution image for p...

Action recognition from depth sequences using weighted fusion of 2D and 3D auto-correlation of gradients features
This paper presents a new framework for human action recognition from depth sequences. An effective depth feature representation is developed based on the fusion of 2D and 3D auto-correlation of gradients feat...

HRM graph constrained dictionary learning for face image super-resolution
Sparse coding based face image Super-Resolution (SR) approaches have received increasing amount of interest recently. However, most of the existing sparse coding based approaches fail to consider the geometric...

Heteroskedasticity tuned mixed-norm sparse regularization for face hallucination
Face hallucination is typically an ill-posed inverse problem, so it is essential to exploit an effective norm-regularized underlying representation. Due to the under-sparsity or over-sparsity, the widely used ...

Efficient single image super-resolution via graph-constrained least squares regression
We explore in this paper an efficient algorithmic solution to single image super-resolution (SR). We propose the gCLSR, namely graph-Constrained Least Squares Regression, to super-resolve a high-resolution (HR...
