Chinese maze: Village makes giant QR code from trees
- qz_ 9y agoI LOL'd at the site headline: "Chinese maze: Village makes giant tech code from trees"
- heroprotagonist 9y agoI tried two QR readers on the photos in the article. They did not detect the code. Would it have been much more effort for the photographer to take a photo that was scannable? Or is there just too much variance in the arrangement and no reader would actually scan it even without a photo?
- jfries 9y agoFor what it's worth, "Barcode Scanner" on Android was able to scan it effortlessly.
- lvsun 9y agoI scanned it with WeChat and the public WeChatID of the company popped out - haomengshenghuo, whose direct translation of english is: life with good dreams.
- kalleboo 9y agoIt worked with the scanner in the built-in camera app in iOS 11, but I had to manually adjust the brightness (issue with scanning off a computer screen?)
- TeMPOraL 9y agoMight be a problem with the combination of your monitor and your phone camera. I tried Barcode Scanner on Android, and it scanned it without a hitch. Hell, I had more trouble scanning a QR code I hand-drawn in blue on white paper...
- heroprotagonist 9y agoHuh, that's kind of odd. I use QR codes for lots of other things and they are successful, though the images are typically more clear.
- frumiousirc 9y agoBarcode Scanner on Android gives: http://weixin.qq.com/r/WD-i_pfE3sqhrdOZ92pK http://weixin.qq.com/r/WD-i_pfE3sqhrdOZ92pK Visiting that link simply forwards me to http://www.wechat.com/mobile/en/ http://www.wechat.com/mobile/en/ Rather anticlimactic.
- paradite 9y agoThat is exactly working as intended. You need to install WeChat and use the app to scan it to go the official account of the tourism office.
- vayan 9y agoIt's Chinese, if there's a QRCode you need to use Wechat. I tried and it's working fine.
- teekert 9y agoIt worked for me. Opens wechat in the Play store.
- userbinator 9y agoAn old QR app I had for a long time (from when QR codes were first introduced, many years ago) failed to read it too. Some of the bits look ambiguous too --- e.g. taking the upper left corner bit of the upper left locator square to be (0,0), what's the bit at (16,11)? It's both noticeably darker and lighter than its neighbours, like it was cut out and then grew back slightly. Those which can't read the code probably use traditional thresholding to reduce the input into 0-1 first, while those which can are using some variation of https://en.wikipedia.org/wiki/Soft-decision_decoding https://en.wikipedia.org/wiki/Soft-decision_decoding algorithm. It doesn't help either that the middle was blanked out, eating into the error correction budget.
- JCharante 9y agoIt worked for me just fine using the QR Scanner on Wechat for QR code that leads to the "village's tourism account on WeChat".
- jpindar 9y agoQR Droid worked fine. So did Google Goggles.
- novalis78 9y agoYes, my car had one too, so anybody could tip it when they thought I was driving well. Fun Bitcoin project of 2012. Though hardly anybody knew what it was, it actually did get some tips.
- dogma1138 9y agoOn a side note about 9 years ago I was involved in a project to study "digital" camouflage and exploitation of the image recognition systems for a GIS solution primarily for governments where patterns were used to "fool" algorithms that identify objects such as buildings and roads. We did identify a few issues with an ESRI/IBM solution, I always wondered if these techniques are being actively used in the field. It won't fool a human analyst but since satellites often operate in mosaic mode these days and generate 10,000s of images per tasked pass CV is often used to identify objects of interest. This QR code reminded me of this.
