Talk:Automatic number-plate recognition

message: Bravo - well done. Congratulations. Informative and interesting. It should definitely win the competiton.-->Energy (talk) 07:44, 5 May 2005 (UTC)
replies: text: Thanks a lot for the positive comments – it's always nice to hear that a good job has been done.  The writing competition is actually over though, with this coming 6th and with many positive comments – that just goes to show the excellence of the other articles!  violet/riga (t) 08:24, 5 May 2005 (UTC)
thread_title:  Excellent article 

message: Who says? There are many systems out there - certainly some of them may run on PCs, maybe even most of them these days. But it's hardly a defining feature of the type; if a company offered a system that ran on Sun servers or IBM mainframes, it would still be a number plate recognition system. — Preceding unsigned comment added by 137.205.31.138 (talk • contribs) 10:15, 5 May 2005 (UTC)

message: Would the "sprays" and other methods of circumvention fall under "Obstruction of Justice"? IANAL, but it seems like that would be a good way for a judge or prosecutor to go.
Of course, you'd have to prove it was done deliberately, and since you can't use the ANPR< I suppose finding the car would be difficult.... — Preceding unsigned comment added by 67.102.135.213 (talk • contribs) 23:15, 5 May 2005 (UTC)
thread_title:  Circumvention 

message: This section is a bit weak - the quote from Gregg whoever is especially unconvincing.  It's important to distinguish between systems like red-light cameras (you get recorded if you break the law), and the (far more frightening from a privacy point of view) average speed measurement systems (you get recorded and kept on file even when you've done NOTHING wrong) - where are the safeguards what happens to the data?  Will they be able to track every law-abiding motorist at whim?  This should be stressed more in this section, I feel. — Preceding unsigned comment added by 193.134.254.115 (talk • contribs) 15:28, 16 February 2006 (UTC)

message: I'd find it helpful if there were parenthesis with abbreviations beside the words that would be abbreviated through the text so that the reader doesn't have to figure out by himself what the acronym means. 132.204.227.146 16:08, 30 March 2006 (UTC)

thread_title:  Crossreference to [[Stockholm_congestion_tax#Technology]]? 

message: There's a lot of work needed here; a featured article review can be avoided by addressing some of the deficiencies.  There are a lot of cite tags, uncited hard data, short stubby sections, a lot of external jumps throughout the text, WP:DASH problems, unformatted incomplete citations (see WP:CITE/ES), attention to non-breaking hard spaces is needed (see WP:UNITS), and attention to WP:MOS#Captions punctuation is needed.  Hopefully some of this can be done so a review can be avoided.  SandyGeorgia (Talk) 15:28, 27 October 2007 (UTC)
thread_title:  FAR 

message: Interesting article at SpiekerBlog (en): Complete forgery detailing Germany's new licence plate typeface: "The official typeface for our license plates is now called FE-Mittelschrift, with FE meaning it is Fälschungs-Erschwert, i.e. difficult to forge." Just a pointer, in case there's any usable information for this article, or somewhere else related. :) -- Quiddity (talk) 08:04, 14 March 2008 (UTC)

thread_title:  FE-Mittelschrift typeface 

message: Sorry, I only have a German Wikipedia account (and I don't want to edit articles without a name), so here just in the discussion section: The German court decision is not presented in its whole. The court decided that photographing number plates over a longer time, and keeping the detected numbers beyond the immediate reason (that may be, "terrorist hunt", or speed restriction enforcement), or using the numbers for other purposes than intendet in the first place, is not conform with German Basic Law). Maybe this text block should be extended to depict this issue more precisely.

thread_title:  German Court decision 

message: I have updated the section on China as some of the grammer was not correct and it was quite difficult to follow. I have also removed the Chinese script, as this would be more suitable on the Chinese version of the page; however, I can't transfer it over as I don't know what it says.
here it is, incase you know what it says and feel it could be transferred to the Chinese version of the article 
只有少部分地方使用该方法，例如青藏公路上有多个这样的点。在南方很少听说有这样的方法来限速。高速公路上一般有流动的测速点和固定的测速点可以自动拍照。

thread_title:  Section on China 

message: Following up and expanding the earlier comment in this discussion, it seems to me the beginning of the article is misusing the term 
infrared ("Systems commonly use infrared lighting to allow the camera to take the picture at any time of the day").
The cameras used for this purpose are either using visible light, or, in some cases, can be extended to pick up the "near infrared" wavelengths.
These are NOT heat, but are the part of the spectrum that are, loosely speaking, very, very, dark red (to the human eye) so appear to be black. 
Looking for actual heat imagery would be troublesome because:
1: the cameras are VERY expensive
2: and have to be kept _cold_
3: and probably wouldn't give you good imaging differential for the numbers on a license plate.
The advantage of using the "near IR" wavelengths is two fold:
a: they tend to cut through haze a bit better than visible light.
b: the cameras are pretty much standard, off the shelf units, and they can use electronic flashes that can be pretty "bright" to the sensors, but are just about invisible to any humans.
Note that the image sensors on most cameras are, indeed, sensitive to the "near IR" wavelengths. This, in fact, is part of how Sony's "nightshot" capability works - they move the IR filter _out_ of the path and activate a "near IR" (and almost invisible) LED source lamp.
(for a good writeup, check:
http://www.batmanagement.com/Ordering/irlight/irlight.html)
Anyway, I'd suggest a bit of a rewording of that paragraph.
