I don't think I've seen any mention of CamanJS, looks interesting. Seems like it might be good to have a mechanism for adding post-processing like a middleware type solution.

There's a bunch of tests that presently fail in Quagga, so maybe one of those failing tests could make a good experiment to see if image processing can fix it. As far as going forward with the project, i think that i'd be willing to figure out how to navigate creating a new npm repo and maintaining a fork with a different name, perhaps something as simple as 'quagga2' or something.

I see that the ownership issue had been dwelling 7 months already, where serratus has offered to hand over the project.

Steps are really simple:. Define ownership and start next phase. Communicate all current developments and categorize according to field. Add the new ideas and categorize the work. Identify the tasks and goals and lets start forking. The first point can also come last. Lets setup a plan, there is more than one person willing to develop.

Quagga2 looks like the best way forward if Quagga1 is delaying development. By the way, the fastest enterprise level is achieved in moonlight, the algo used by quagga will be served best with achieving moonlight, even when if it is dark, try it. Standard barcode white on black, moonlight illuminates the white bg making the black lines more visible. An example to increase precision pre processing. I am going to start with ml to recognize trends in errors.

Well, I haven't been pushing real hard on resolving things, because I have a day job and a side gig that take up a large amount of my time, though it's the side gig that uses Quagga.

Until I upgraded to a phone with a much higher resolution camera, Quagga was working flawlessly for me. Newer phone, newer camera, things are not working quite so well at all now. So I was hoping that the ownership problem would end up being resolve by others, but it turns out that I'm still the most active here.

Both Tomas and I have ability to merge to quagga repo, and have done some merging since, but we haven't really been getting too much in the way of complete pull requests.

Maybe start with a 0. That's interesting, I keep digging about Quagga and I found this discussion. Malavos hello! Some weeks ago we were looking at quagga to work on a scanner app for VIN's.

We ended up using Google's Mobile Vision.Bump acorn from 6. Sure, code and samples help. Might be helpful to know what sort of hardware you're trying to use with, as well, I've been completely unable to get, for example, my PC's webcam to recognize anything at all, no matter what settings I try to use. My laptop occasionally has results.

But for the most part, I only really have success with a cell camera. Where communities thrive Join over 1. People Repo info.

Apr 09 Apr 08 Apr 07 Apr 06 Apr 05 Apr 03 Eric Blade. The only thing I can come up with is that there's some difference between your dev configuration and your live configuration that is creating something invalid.

Perhaps live is minifying the already minified quagga? We used uglifyJsPlugin which didnt play nicely with quagga in production. I just changed the optimization in my webpack. Maybe adding section on webpack compatitablity with regards to minification.

Hello, first, thanks so much for creating and maintaining this project. I am new to QuaggaJS and just set up my first proof of concept. Unfortunately, I am getting poor results. The green box takes a long time to recognize a barcode, and when it does it spits out garbled text as opposed to what is actually encoded on the barcode. I can post my code and sample barcodes if it will help -- I am mostly wondering if there is any obvious error on my end or if anyone else has had this experience.

I know none of that has anything to do with barcodes, but I think that Quagga can make a good interface to any kind of image recognition, not just barcodes, but I don't want to tack the non-barcode stuff into the main. It may require a major version bump to address. I ended up stop using Quagga, Google Vision worked pretty well for me.

Stack Overflow works best with JavaScript enabled.QuaggaJS is a javascript library project maintained by Christoph Oberhofer, that allows devices to use their cameras as barcode scanners, both in static and live images.

First and foremost, it was difficult at first to find information on QuaggaJS. The majority of other developers I worked with despised web barcode readers citing that they were slow at reading and difficult to work with. I found Quagga to be very easy to work with, after some minor modifications. If anyone, including the creator would like to correct me, please do. The I realized their might be a simpler way through use of a CDN where both the full and minified versions of the QuaggaJS library are available:.

NET 4. The view has a corresponding js file containing all of my javascript for the page. This section controls everything on the page, there is no JS in my markup page. The majority of the heavy lifting is done by a single function. The second part of the initializer includes scanning frequency, used for the number of times in a timeframe it will attempt to scan, and numOfWorkers- which from what I could surmise, was the number of threads attempting to locate and read a barcode in the live stream.

I reduced mine from 10 to 1 and it seemed to work a little faster on in my browser Google Chrome Version The initializer also includes the decoder. As you can see below, my onDetected handler loads the hidden field with the scanned code value, loads information to the page using a function that calls ajax, then automatically clicks the button, if I wished that found barcode would close the viewscreen of the scanner and toggle my button text.

Removing it would bring the application closer to the version I mentioned in my opening statements. As you can see QuaggaJS is pretty simple to use for this one purpose, while having a multitude of functional operations such as scanning static images and more. I hope this helps someone out there and please feel free to comment on this if you have QuaggaJS experience.

I didn't find any other articles on QuaggaJS in CodeProject, so I hope this article helps someone with their own implementation. Feel free to comment and contribute as I am not a QuaggaJS guru.

It works very well, and this is my initialization code:. What does that mean? When it recognize a barcode I need to ask the user if he wants to accept or reject the decoded value - and therefore repeat the process. I guess this is due the behavior of the stop method:. Additionally, if a camera-stream was requested upon initialization, this operation also disconnects the camera. For this reason I'm looking for a way to pause the decoding, so the last frame is still there and the camera has not disconnected yet.

You can get the image frame via Quagga. With that, you can overlay the videostream. Learn more. Asked 2 years, 11 months ago. Active 2 months ago. Viewed times. It works very well, and this is my initialization code: Quagga. It would be nice to leave the captured image so he can actually see what he just captured. I guess this is due the behavior of the stop method: the decoder does not process any more images. Any suggestion how to achieve this?
