Yes, we have SHA1 values for the Commons hosted images, however a local checksum is not normally available from the source (e.g. NYPL) which means re-downloading the original to do the comparison. As some of my uploads are over 100mb for one page, it's an expensive solution. >> * uploads that are mostly blank pages >> in old scanned books.

For PDF you can try to use Poppler/poppler-utils or > MuPDF. For images it will be bit more involved ... but intressting. Formats are normally jpeg or TIFF. My blank detection uses analysis of pixel colour deviations over parts of the image to deduce if it looks blank. This uses the basic Python Image Library rather than any sophisticated math. This can happen pre-upload by testing a client-side image.

Fwd: [Wikimediauk-l] 3rd party Dictionary of Species taking a feed from Commons via Wikidata

Take a look: http://www.llennatur.com/Drupal7/llennatur/?q=node/6#Gl%C3%B6yn It also includes clickbacks to corresponding articles on Wikipedia. All thanks to Wikimedia UK and the University of Bangor. There a couple of thousand images missing on Commons, and if anyone can help, there's a Wikiproject here to fill the gaps.

GSoC 2016 | Porting catimages to pywikibot-core
by Abdeali Kothari 19 May '16

19 May '16

Hi, I'm a student from Chennai, India and my project is going to be related to performing image processing on the images on commons.wikimedia to automate categorization. DrTrigon had made the script catimages.py a few years ago which was made in the old pywikipedia-bot framework. I'll be working towards updating the script to the pywikibot-core framework, updating it's dependencies, and using newer techniques when possible. catimages.py is a script that analyzes an image using various computer vision algorithms and allots categories to the image on commons. For example, consider algorithms that detect faces, barcodes, etc. The script uses these to categorize images to Category:Unidentified People, Category:Barcode, and so on. If you have any suggestions and categorizations you think might be useful to you, drop in at #gsoc-catimages on freenode or my talk page[0]. You can find out more about me on User:AbdealiJK[1] and about the project at T129611[2].

Co-ordinates for a path

All, I have some videos of the seabed of the Dogger Bank, which includes some footage of wrecks on the bed, marine life, and parts of prehistoric settlements. I have the exact co-ordinates of the videos - however, because it's a video, the co-ordinates change over time, and the *moving *co-ordinates of the file can't really be entered into Commons - or can they? Can anyone help with this? * *What's the best way to record the co-ordinates if they move over the duration of the video?** Richard Symonds Wikimedia UK 0207 065 0992 Wikimedia UK is a Company Limited by Guarantee registered in England and Wales, Registered No. 6741827.

Size of images donated
by Romaine Wiki 07 May '16

07 May '16

Hi all, A professional photo agency offers us (Wikimedia Belgium) a donation of images of art works. They now offer as a start these images with 595 x 842 pixels at 72 dpi. This size is almost double of that from a thumbnail size on Wikipedia. My own (not the most modern) smartphone makes images at 5.312 × 2.988 pixels at 72 dpi. Seeing the size of these images I think they are to low. My question is: what is the minimum of quality we should ask? Thanks! Romaine
