Talk:Pixelation

Latest comment: 4 months ago by Bruce A. WIlliamson in topic Is this pixelation?

I question the validity of 72 dpi for screen resolution This has been the historical desktop resolution for Macs, but PCs run at a typical 96dpi

Perhaps this measurement was from the typical dot pitch of older monitors. a .26mm dot pitch monitor would be around 96dpi resolution 25.4 mm per inch / .26mm dot pitch = 97.69 dpi correct me if I'm wrong.

This is much different than the calculated resolution from a CRT

I realize that theoretical resolution and actual resolution are two different things.

But LCD screens used today have an inherent resolution

to see someone's opinion of CRT vs LCD dot pitch, scroll down this linked page and read this person's opinion.[ http://www.bestsyndication.com/Articles/2006/dan_wilson/sci_tech/06-07/060706_lcd_tft_crt_monitor_comparison_product_review.htm]

I find the 72dpi screen resolution rule to be outdated and misleading. Probably a rule from the era of CRT monitors.

I edited that to "about 100 dpi"... my slightly old LCD is around 96, my newer laptop screen is 106, my cell phone is 170 dpi... Resolution varies a lot by size, with 1920 x 1080 pixel monitors coming from around 20 to 40+ inches. ---HKMarks(T/C) 14:56, 26 December 2009 (UTC)Reply

Remove incorrect photo edit

I removed File:Pixelation example.JPG from the body (picture of a rangehood or something). The original version of the file appears to be an example of error diffusion dithering, not pixelation. The current version has been downsized which eliminates the dither effect, making it completely irrelevant. —Preceding unsigned comment added by Adx (talkcontribs) 00:57, 27 January 2010 (UTC)Reply

Remove Adobe Advertisement edit

Bicubic resampling is a simple algorithm that we encounter in almost every modern image viewer/editer and is not unique to Adobe's Photoshop. Wouldn't it be better to remove the "Adobe Photoshop" from the box on the right bottom side?--92.161.179.197 (talk) 19:20, 24 August 2010 (UTC)Reply

Pixelated was a term used in an early Cary Grant movie by an eldery lady and her sister refering to the fact they were going to get drunk on wine or brandy. cir approx 1930ish. Will research and update.

This was WAY before electrons were used to display pictures.67.233.255.140 (talk) 02:27, 10 December 2010 (UTC)Reply

Pixellation is also the filmmaking term for stop-motion animation of live actors. — Preceding unsigned comment added by 184.77.250.54 (talk) 18:13, 7 April 2012 (UTC)Reply

Censorship Pixelation edit

That section was a joke, right?
No references, extremely obscure content, and even if it were true, totally irrelevant to a technical article on pixelation (just because someone may have used pixelation for creative purposes doesn't mean every occurrence of this has to be listed here).
So, I've removed that section.

It's not clear whether you're referring to the "Censorship Pixelation" section you removed or the "Deliberate pixelation" section, likewise. The term 'pixelation' (or 'pixelization') applies to deliberate as well as inherent limits on image resolution. It's a commonly-included effect in image editing software (whatever the end use). The article isn't restricted to technical aspects. Also—not that two wrongs make a right—the rest of the article isn't supported with references either. I've restored the section on deliberate pixelation. Pololei (talk) 23:09, 9 February 2018 (UTC)Reply

Why are there no sources? edit

Did the person who originated this article get lazy or something, because there are no sources listed, can someone please fix that? Superkid761 (talk) 13/02/19 —Preceding undated comment added 14:34, 13 February 2019 (UTC)Reply

Is this pixelation? edit

I worked in a company that performed video compression. We called this macro-blocking. Pixelation is an entirely but similar process. Bruce A. WIlliamson (talk) 01:39, 2 December 2023 (UTC)Reply
