Is this as clever as I think it is?

Hail everyone! <D
Over the past few days, I've been hard at work on a rather interesting program of mine that expands small images to much larger proportions - Using a pixel reclamation technique of my own creation to do it with a much lower loss of quality than the typical "stretching" of an image. :D

In plain English: Most of us have probabally found the perfect image for whatever we need on Google ImageSearch, but have found the same image to be too small for what we want. This program allows that image to be "expanded" to a decent size without the quality being too badly affected. :)
Indeed...The reason that I created this program in the first place was because I'd found a good scan-in of the Warhammer 40,000 v2 box artwork on a P2P service - But at 1052x800, it was too small for me to use as a desktop background on my 1280x1024 display. :|

Anyhow...I ran a few tests of the program last night using a fairly complicated 100x100 image from Google as source data, and the results certainly seem quite good to my eye - Although I admit that the program does seem to "fuzz" the images a little. Anyhow, here's a collage that I put together to show how well it works compared with traditional "stretching" methods:


JPEG version - 140Kb, PNG version - 1.45Mb (Coming soon)​

Anyhow...What I'm mainly interested in are other people's opinions on my work here. Is it as complex and clever a project as I'm led to believe it is (Ye wouldn't believe the difficulty I had coding it! :razz:) or could I have used my time better on a different project? 8)

Later edit: If anyone's interested in having a play around with this themselves, I've attached a public GNU GPL licenced version of the program to this post. Enjoy! :D

Farewell for now, and looking forward to hearing any feedback and opinions! <D

I reckon there would be a huge benefit for this use in fighting crime, if a cctv image a car could be done in the same way to identify its license plate then this new program could have huge advantages.

Yes your right it would be a huge benifit!

Hmm...I never looked upon it with that in mind, admittedly - But given the technique employed to expand the images themselves (Which works only on data available inside the image) I don't honestly think that it's output would be "solid" enough to stand-up in Court. :?:

On the other hand though...If the Police and other law enforcement agencies could make use of it to clarify illegible number plates for vehicle identification and suppliment it with other evidence, then I certainly wouldn't raise any objections to it being used in such a manner! 8)

Anyhow...After slaving away for a good eight hours straight tidying up odd bits 'n' bobs in the program, and writing out some half-decent documentation for it (All 21Kb worth! :shock:) I've managed to come up with a public version of the program - Licenced under the GNU GPL v3 - That I'm happy to release. :D

If anyone wants to download it and have a play around, I've attached the program to my original post as a ZIP file. Please bear in mind though that this thing hasn't been extensively tested (It's known to work on XP Pro SP2, but I havn't any other systems that I can test it out on for compatability.) and needs to be regarded as such. :!:

Please remember to check-out the program's Readme file before use for operator info, and warnings that need to be heeded. Thanks! 8)​

Farewell, and hope that ye all enjoy this latest creation of mine! <D

It came to mind today that I'm pretty certain that NASA, the FBI and some other agencies in the USA, not to say that ASIO or MI6 don't, but I think this software or at least a program that enhances the pixles to make a badly pixlated image more sharper and clearer might already exist. Should look into it.

Photoshop and other such packages blow up pictures better than this, IMO. Pretty impressive for a homebrew, though!

You seem to be the sort of person whom could sort out those tecnical problems with the 180s and Merseyrail 508s !

I think there is already a program that does that. Think the Police and forensics use it.

Do they have pixelating problems?

I think this shows the scale of the issue:

That one was an unfortunate case, it was in service when it started to pixellate.

Resulted in the service being terminated there so another 180 could come and rescue it.

Unfortunately, it also pixelated, and then caught fire. Seems Northern are having a heck of a lot of trouble with them.
