Sampling signals with finite rate of innovation
The authors consider classes of signals that have a finite number of degrees of freedom per unit of time and call this number the rate of innovation. Examples of signals with a finite rate ofExpand

Perceptual blur and ringing metrics: application to JPEG2000
We present a full- and no-reference blur metric as well as a full-reference ringing metric. These metrics are based on an analysis of the edges and adjacent regions in an image and have very lowExpand

Sparse Sampling of Signal Innovations
Sparse sampling of continuous-time sparse signals is addressed. In particular, it is shown that sampling at the rate of innovation is possible, in some sense applying Occam's razor to the sampling ofExpand

A no-reference perceptual blur metric
We present a no-reference blur metric for images and video. The blur metric is based on the analysis of the spread of the edges in an image. Its perceptual significance is validated throughExpand

A hybrid watermarking scheme for H.264/AVC video
A novel H.264/AVC watermarking method is proposed in this paper. By embedding the robust watermark into DCT domain and the fragile watermark into motion vectors respectively, the proposed method canExpand

Automatic segmentation of the choroid in enhanced depth imaging optical coherence tomography images
Enhanced Depth Imaging (EDI) optical coherence tomography (OCT) provides high-definition cross-sectional images of the choroid in vivo, and hence is used in many clinical studies. However, theExpand

Automatic knee cartilage segmentation from multi-contrast MR images using support vector machine classification with spatial dependencies.
Accurate segmentation of knee cartilage is required to obtain quantitative cartilage measurements, which is crucial for the assessment of knee pathology caused by musculoskeletal diseases or suddenExpand

Fragile Watermarking Based on Encoding of the Zeroes of the $z$-Transform
In this paper, a new fragile watermarking method for digital image authentication is proposed based on the zero locations of the z-transform. The z-transform domain is a new transform space forExpand
