Talk:Resolution

Spatial and temporal resolution

I've disambiguation-ified this page. However, I can make neither head nor tail of the following two paragraphs, so I've decided to stick them here in hope that someone will be able to clarify it and paste it where it belongs. --Smack 03:09, 17 Apr 2004 (UTC)

Technicians (engineers and scientists) addressing technicians have a more specific meaning when talking about resolution of an imaging system. They are generally talking about spatial resolution, though when talking about moving picture (film or video) systems, they may be talking about temporal resolution. Spatial resolution is usually measured by the Modulation Transfer Function (MTF), which is a relationship between contrast and spatial frequency.

Contrast is defined as the difference between dark and light areas, measured in density (film), or electrical units (imaging sensors), or bits (digital camera systems), divided by the sum of the dark and light areas. This value is measured or calculated and plotted against spatial frequency, measured in cycles per millimeter.

Contrast formula in LaTeX

The source text of the cut paragraph above included

Contrast is defined as the difference between dark and light areas, measured in density (film), or electrical units (imaging sensors), or bits (digital camera systems), divided by the sum of the dark and light areas. < !-- this cumbersome description to be replaced by the formula as soon as I figure out LaTeX - eh -- > This value is measured or calculated and plotted against spatial frequency, measured in cycles per millimeter.

I'm not sure if "you" care about the hidden comment, but if so this may help:

${\frac {DarkArea-\mathrm {LightArea} }{{\mathit {DarkArea}}+\mathbf {LightArea} }}$

You can fill in whatever for DA and LA, and for style.

Logic

What happened to the logic meaning?

In need of a major edit

I'm not sure how to go about doing this without stepping on toes. I'm the EH who was responsible for the text snipped above. I don't care that it didn't seem to fit in, but I don't know how to proceed with a better treatment than what exists now. When I started on this, there were a few false starts on resolution, but I think a good organization of the optical resolution part goes as follows:

• Lens resolution - discussion of Rayleigh criteria, etc. The angular resolution page addresses this, but most people would be looking for *optical* resolution, not angular.
• Sensor resolution (imaging sensor) - the first paragraph above was a rough draft intended to address the difference between non-technical measure of sensor resolution (typically expressed in the number of pixels) and the technical measure of spatial resolution (typically expressed in lppmm, lines, contrast vs. cyc/mm, or MTF (the modulus of OTF))
• Sensor resolution (imaging sensor, especially high speed systems) - the time or temporal resolution. An imaging system running at 24 frames per second is essentially a discrete sampling system that samples a 2D area. Film is one type of imaging sensor; CCD and CMOS are the modern preferences, though a thorough discussion would also include things like Vidicons, Plumbicons, image intensifiers, photovoltaic and photoconductive infrared systems, bolometers, pyroelectricss, etc. Pyroelectric detectors require choppers and have interesting temporal characteristics that look like a bandpass.
• Transmission and recording mechanism resolution - the NTSC signal is usually band limited to 6 MHz. That translates to a finite spatial resolution. Analog tape recorders are also band limited. Digital transmission and recording systems have a spatial resolution also, but it is more variable due to compression considerations.
• System resolution - the use of Fourier transform techniques to combine optical, sensor, and other effects into system resolution. Coherent vs. incoherent imaging (effect of phase, holographics)
• Display resolution - Display resolution is the one place that pixels are a legitimate measure, though a very technical analysis would include pixel pitch and size.
• Ocular resolution - the human eye
• Finally, a discussion of atmospheric effects on resolution, including Kolmogorov turbulence, Fried's seeing diameter, aperture averaging, benefit of short exposures, etc. Should include some discussion of corrections to parameters discussed above -- system resolution, turbulence-limited vs. diffraction-limited seeing, adaptive optics, guidestar, super-resolution, multi-frame blind deconvolution

Resolution (settlement)

Is Resolution (policy debate) the same thing as a Resolution to a problem? ex. The Resolustion of a story, the Resolution of Fighting or a War. I suggest a page of Resolution (settlement) for the ending of something. Am I mistaken?

I've added a link to an artical about Resolution (settlement) that needs to be written. STHayden ^{[ Talk ]} 02:14, 22 August 2006 (UTC)

I created the page but it has been deleted. Still trying to figure out the best way to handle some of the links to this page -- STHayden ^{[ Talk ]} 17:58, 22 August 2006 (UTC)

According to the logs, Resolution (settlement) was deleted because it appeared to be a dicdef. In general, redlinks on dab pages are discouraged. -- RoySmith (talk) 13:12, 6 November 2006 (UTC)

In Literature

Any reason why the short Literature definition doesn't link to the someone more complete page on Denouement. I think it would be appropriate. —The preceding unsigned comment was added by AmRadioHed (talk • contribs) 06:31, 12 December 2006 (UTC).

illustrations/examples

I came looking to find the proper form for a resolution, of the type for a deliberative body. I know of the "whereas" element, but am unsure of common or best structure -- for example, may each "whereas be followed by its own "resolved", or does that make it multiple resolutions? should the "resolved" portion be broken down into constituent parts, and if so, in what sort of order?

If I knew these things, I'd do an edit to put them on, or would do so if I could find them elsewhere. But after nearly an hour on google, I found nothing helpful. So if there's anyone out there who knows, I'd appreciate something appearing here.

Or should I say,

Whereas I have been unable to find any guide on the proper form of a resolution, Be it resolved that someone, somewhere, ought to do so.

MIssing definition: resolutions

The resolutions conducted by shareholders/directors is not listed here. Perhaps someone should list it on - I came on here to look for the specific definition - i think a resolution is something that shareholders pass at general shareholder meetings. someone should add this in as i don't know how to. --220.239.108.93 12:48, 9 June 2007 (UTC)

Optics and electronics

Surely optics and electronics should come under Science. —Preceding unsigned comment added by 86.21.224.201 (talk) 18:58, 20 November 2007 (UTC)
