-identify option is not detecting image corruption(?)

Post by troesler »

Hello,
I am new to ImageMagick and am looking to implement a script to scan my photos directory for any corruption so that I can be notified and can take action. Reason being that I recently discovered that Windows (or some driver or hardware) caused wide-spread corruption of my photos - mainly consisting of images where the thumbnail appears normal but when the full image is open a large section of the image is greyed-out.
Once I get this command working manually I would like to script it either in PowerShell or more likely Perl which I am more familiar with.

For the purposes of manual testing I have been trying the following in PowerShell.
From what I read this should report an issue with the image (since the image is indeed damaged as detailed above - large section is greyed-out).

PS C:\Program Files\ImageMagick-7.0.4-Q16> magick -regard-warnings ./013.jpg -identify C:\temp\013_2.jpg
./013.jpg JPEG 2448x3264 2448x3264+0+0 8-bit sRGB 393KB 0.125u 0:00.121
PS C:\Program Files\ImageMagick-7.0.4-Q16>

Am I doing something wrong here? It doesn't seem to be detecting any corruption of this image...
Also is there a way I can avoid specifying an output file? I only want to detect the corruption for now.

Thank you in advance!!

If the image is valid, but mostly gray, that command won't report a problem.

Perhaps you can post a URL to an example.

An image that is mostly gray will average to a colour that is close to gray, with a low standard deviation.

You could also extract the thumbnail (with exiftool) and compare its statistics with the main image.

you do not need any output images only input images.

Code: Select all

magick identify image1 image2 image3 ... imageN
should list information about each of the images to the terminal

-regard warning will report warning messages also that often come from TIF meta tags that IM does not show. These are not errors, so you probably do not want to see them.

see http://www.imagemagick.org/script/identify.php

but in IM 7, you have to put magick before identify. (no hyphen)

"identify -verbose 029.jpg" or "convert 029.jpg x.png" clearly show that file is corrupt.

I didn't get an error on my side wh n I tried verbose. Just a whole lot of details about the file/photo.
Would you mind pasting some or all of the error message you see on your side?
I'm away for the next 10 days but will follow up when I return. Thanks for all your help!!

I got the same messages above in my post without going to stderr.

Thank you I now see the corruption messages when I test with that file.
However I have tested with some other known-bad files and no corruption is being reported.

Here is an example - similar to the other example provided it is mostly greyed-out:

Your link doesn't work for me; I get a blank page.

Perhaps the file is valid, with an image that is mostly gray. If this is always the same shade of gray, you can easily write a script to detect it. For example, turn all other colours black, and turn this gray into white. Then the mean value of the pixels is the proportion that were gray.

Not sure why you can't access the link - I tested it from another system and my phone and it works from both.

I like your suggestion though, since in all the examples of this issue I have looked at (and likely all photos this is happening with) the corruption manifests itself with the exact same grey color taking up some portion of the photo.
Could someone point me in the right direction for how to structure the command line call to detect if the photo has more than say 5% of this specific color?

Grey/corruption color = [Red:128, Green:128, Blue:128, Hue:160, Sat:0, Lum:120]

Windows CMD syntax. Adjust as required for other shells.

Code: Select all

convert input.png -fuzz 1% -fill Black +opaque gray(50%) -fill White -opaque gray(50%) -format "%[fx:mean>0.05?1:0]" info:
This returns "1" or "0".

The fuzz 1% allows for slight rounding errors. 50% gray is turned to white and other colors to black, so "%[fx:mean]" would return 0.0 (no pixels are gray) to 1.0 (all pixels are gray). We compare this to "0.05", so an output result of "1" means "more than 5% are gray".

You can put the result into an environment variable, or directly report it or whatever you want.

EDIT: Today, I can see your picture, but can't download it. Weird.

EDIT2: Now I can download your picture. The problem may be my bad internet connection timing out.

My command works for your image. It is JPG, so the gray isn't a constant colour, so the fuzz is needed. 0.869 of the pixels are 50% gray, and this is more than 0.05, so the command returns "1".
