Does anyone know how to tell if an image has been photoshopped?
edit Specifically, I want to determine if regions or pixels in the image have been altered by photoshop. I'm not as interested in finding errors in the photoshop job (missing shadows, errors in reflections, etc)
I seem to remember something like a high-pass filter that you could use that would determine the noise levels. Edited regions would have less noise, or at least changes in noise. I'm having a hard time finding information on this or other approaches.
Thanks for your help!
I use this website to check if an image is photoshopped or edited:

Google is your friend for many relevant results.
maybe fotoforensic works. its an online program to compare the no of times a photo has been compressed. the no differs for the original image and the added image. hope it helps u.

I would give a try with error level analysis:
http://www.errorlevelanalysis.com/
Follow the links on that site and maybe get in contact with the author, I'm sure they can give you the needed pointers.
The first thing that you have to check is the properties of the file.
If it was last save via photoshop, there should be a meta data under "details" -> "origin" -> "program name". :)

It may sound like other questions related to this matter but I don't have any problems opening rectangular .png files. Seems like my computer has problems only with non-rectangular pictures (e.g. triangular play button without the background). What can be done? I think there's no need to provide a reproducible example. Appreciate all the help.
EDIT: the error is as follows
I think you forgot to put your picture in your project folder because I once made that mistake for a game that I made. You should also maybe remove Resources/res/ from the loadFromFile code.
I'm using rectangle and circle shapes with textures loaded form file without problem, transparent .png's too. If you are absolutelly sure that your code is correct, you got correct file address etc.. Maybe there is a problem with image. Try to load some another image where you 100% know that it works fine. Maybe your antivirus is messing with your projects,. Check if you have exception for your project directories. I could be more specific if you provide some code of your attempt to us.
is it in sulu possoble to get a resized image on the fly with custom dimensions, without the need to define an image fomrat before? A kind of "dynamic image format".
Reason is, that I would like to define multiple versions of an image based on some code calculations in order to fill the srcset attribute of an image.
Thx a lot!

Not by default, but you might be able to override some parts of the FormatManager, but I am sure you would break some of Sulu's functionality that way (e.g. purging the cache for all image formats probably won't work anymore, or you can't manually crop that non-existing format). However, I have also not tested it, and I am not sure if that really works :-/
My attribute tables and icons are tiny in QGIS.
I believe this may be because I have a new high-res monitor.
Check out my screenshots - everything is super tiny. And in the attribute table, the row heights are not right.
Also - How do I zoom into the attribute table?? Normally this is ctrl-mouse wheel or ctrl+/-
Can't seem to find an answer to my question anywhere.
The answer is given by #Stu Smith here, with some clarifications that we worked out.
The detailed directions are here, written well for layman's, with step by step instructions and a nice video.
What's great is you can do this for any program you're having a problem with.
It's super easy, a 2-step 5 minute process. You have to add a file in the registry, and then in the Program Files folder, add another file.
Couple notes:
*For qgis specifically: where the following file is: qgis-bin.exe rename the file to add to the folder to qgis-bin.exe.manifest.
*When I chose decimal and reopen it, it shows that it's back to hexadecimal. This doesn't matter at all. An explanation is on the bottom here.
*The resolution will be lower, and things will look that way. In this case, not really a big deal, should affect your results, but not sure with programs where resolution matters, like Photoshop. Anyone give their experience or knowledge with that in the comments.
First, sorry for my English. I have a question regarding tesseract. Is there a way to recognize text in a graphic or a picture without having to clean the image you want to recognize? in what I read there to clean the image first, remove graphics and photographs and leave only the text. But I want the user to upload to the server and newspaper clippings you can recognize this news without human intervention. It can be tricky. But if you know any other way I could do as they are grateful. Thank you very much
No, you can't.
Tesseract is made for reading text and only text. When you perform OCR on a subject with both text and an image, Tesseract spits out things it finds in the image (garbled crap).
You can detect image regions and crop them out, though. I think that would be a better question to ask.
I would like to ask if anyone knows a software that can be modified and used on my website. I need a tool that will be able to add multiple images resize and move theme. Something like THIS but with multiple images support...
Beside that I need a canvas to be fix (width, height, dpi...) So the produced image will always have the same specifications...
Thanks for your answer!
