Очень круто! Просто великолепно, я начинающий программист самоучка, мне очень интересна тема компьютерного зрения, то что я видел это просто превосходно!
i read and looked at the code for optical flow for opencv but i cant get it to track my qrcode. the doc site of opencv is not telling how to combine it with zbar. can you help me?
Correct combination of different algorithms is the key to success in this case. Unfortunately, at the moment the source code cannot be opened, since it is used in commercial projects. I advise you to carefully study the input and output data of these algorithms and come up with a way to mutually refine them.
sir, i am Korean university student. i have readied for graduation, making bar-code product. but i was in Difficult situation. Could you teach me how to make bar-code product which is / I want to find some bar code in app bar cord database so select that bar code in app and I will find same bar code with phone camera on goods.
@@yurivolobuev3223 On more thing I would like know, if you kindly want to share the idea. How you are deciding when to leave the LK tracking and hand over the process to detection algorithm? Are you checking if the polylines are forming square or not if not then again handing over to detection? Since I have seen you are shaking your hand when square is little bit deformed which I think to turn it more deformed in order to trigger the detection again. Am I right on this?
@@yurivolobuev3223 And as you are getting such tracking in LK I think you will get even more astonishing result in Dense. Because I have found in LK tracked points are more prone to drift than dense of.
Love the vid, respect the game. Taking open source code, rewriting it, and selling it off to some client. Hats off man!
Please make a tutorial for how to do this

Nice trick
nice vid , plz can you share source code ?
Do you have to have a specific scanner or will it just work through the camera
Simple monocular smartphone camera
@@yurivolobuev3223 how did you connect your smartphone whit your pc?
@@walidmat8972 I didn't. It is android application.
@@yurivolobuev3223 did you code this app or it's avalible on playstore ? where can i get the source code ? thanks
Sir please make tutorial
how to do this in unity
Build native library for each platform in android studio, visual studio, xcode, and send frame to it
where i get guide for using optical flow
docs.opencv.org/3.4/d4/dee/tutorial_optical_flow.html
@@yurivolobuev3223 Are you using dense or sparse optical flow?
@@smithangshuIn this example, the Lucas Canada algorithm was used. But dense works well too

nice one👍
very interesting, could you please share the source code?
I can't, the code is already in use in a commercial application. But the video has tips on what to use
