Bouman] | [http://forum.doom9.org/showthread.php?t=160038&page=2 Discussion]<br> The design is based on the lowpass characteristic of the contrast sensitivity of the human visual system. The Filter is chosen so that a cascade of the quantization system and the observer's visual modulation transfer function yields a whitened error spectrum. The resulting images contain mostly high frequency components of the display error, which are less noticeable to the viewer.

===False Contour===
 +
Also known as [http://en.wikipedia.org/wiki/Colour_banding Color Banding] and Posterization. Posterization and false contouring are definitely the same thing. Banding can absolutely be used in the same way, but is also used to describe a very different phenomenon where vertical or horizontal "bands" are seen on screen (sort of delineated by differing amounts of darkness/lightness). But yes, they can be all used to describe the same phenomenon.[http://www.avsforum.com/forum/167-plasma-flat-panel-displays/1354487-posterization-banding-false-contouring-all-same.html#post20833953]

*[http://www-m3.ma.tum.de/bornemann/inpainting.pdf Fast Image Inpainting Based on Coherence Transport] - High quality version of paper, pdf. Based on a detailed analysis of stationary first order transport equations the current paper develops a fast noniterative method for image inpainting. It traverses the inpainting domain by the fast marching method just once while transporting, along the way, image values in a coherence direction robustly estimated by means of the structure tensor. Depending on a measure of coherence strength the method switches continuously between diffusion and directional transport. It satisfies a comparison principle.<br>

==Image Scaling==
[http://new.ics.ele.tue.nl/~dehaan/pdf/90_jsid2003.pdf Subpixel Image Scaling for Color Matrix Displays, Michiel A. Klompenhouwer, Gerard de Haan] - Subpixel rendering’ algorithms are being used to convert an input image to subpixel-corrected display images. This paper deals with the consequences of the subpixel structure, and the theoretical background of the resolution gain. We will show that this theory allows a low-cost implementation in an image scaler. This leads to high flexibility, allowing different subpixel arrangements and a simple control over the trade-off between perceived resolution and color errors.<br>

*[http://www.iop.org/EJ/abstract/0266-5611/25/1/015002 A scaled gradient projection method for constrained image deblurring] - A class of scaled gradient projection methods for optimization problems with simple constraints is considered. These iterative algorithms can be useful in variational approaches to image deblurring that lead to minimized convex nonlinear functions subject to non-negativity constraints and, in some cases, to an additional flux conservation constraint. A special gradient projection method is introduced that exploits effective scaling strategies and steplength updating rules, appropriately designed for improving the convergence rate. We give convergence results for this scheme and we evaluate its effectiveness by means of an extensive computational study on the minimization problems arising from the maximum likelihood approach to image deblurring. Comparisons with the standard expectation maximization algorithm and with other iterative regularization schemes are also reported to show the computational gain provided by the proposed method.<br>

[edit] False Contour

Also known as Color Banding and Posterization. Posterization and false contouring are definitely the same thing. Banding can absolutely be used in the same way, but is also used to describe a very different phenomenon where vertical or horizontal "bands" are seen on screen (sort of delineated by differing amounts of darkness/lightness). But yes, they can be all used to describe the same phenomenon.[1]
