TLDR
A new reduced- reference IQA metric to calculate the diversifications based on contourlet transform is proposed and results illustrate that even with low data rate, the presented metric has still good consistency with the subjective perception.Abstract:
In reduced-reference (RR) image quality assessment (IQA), the visual quality of distorted images is evaluated with only partial information extracted from original images. In this paper, by considering the information of textures and directions during image distortion, we propose a new reduced- reference IQA metric to calculate the diversifications based on contourlet transform Experimental results illustrate that even with low data rate, the presented metric has still good consistency with the subjective perception.read more

No-reference image quality assessment in contourlet domain
TL;DR: The contourlet transform is utilized to NSS of images, and then the relationship of contour let coefficients is represented by the joint distribution, and an image-dependent threshold is adopted to reduce the effect of content to the statistical model.

The Laplacian Pyramid as a Compact Image Code
Peter J. Burt,Edward H. Adelson +1 more
TL;DR: A technique for image encoding in which local operators of many scales but identical shape serve as the basis functions, which tends to enhance salient image features and is well suited for many image analysis tasks as well as for image compression.

The contourlet transform: an efficient directional multiresolution image representation
Minh N. Do,Martin Vetterli +1 more
TL;DR: A "true" two-dimensional transform that can capture the intrinsic geometrical structure that is key in visual information is pursued and it is shown that with parabolic scaling and sufficient directional vanishing moments, contourlets achieve the optimal approximation rate for piecewise smooth functions with discontinuities along twice continuously differentiable curves.

A filter bank for the directional decomposition of images: theory and design
R.H. Bamberger,Mark J. T. Smith +1 more
TL;DR: A directionally oriented 2-D filter bank with the property that the individual channels may be critically sampled without loss of information is introduced and it is shown that these filter bank outputs may be maximally decimated to achieve a minimum sample representation in a way that permits the original signal to be exactly reconstructed.

Statistical evaluation of image quality measures
TL;DR: It was found that measures based on the phase spectrum, the multireso- lution distance or the HVS filtered mean square error are computa- tionally simple and are more responsive to coding artifacts.
