• What I wish I knew before building a Shopify App

  Sometimes libraries do a switcheroo where they run interpreted code on startup to locate the "real" implementation in a shared object, and then load that and replace themselves with it. I'm not sure this is really idomatic, but here's an example of what it looks like from OpenCV:

• Facial Recognition with Machine Learning
  reddit.com/r/AskProgramming | 2021-03-04

  You have to do facial recognition without using deep-learning? That's pretty crazy I would say. But still, try looking into OpenCV's Documentation. Some stuff will be Deep learning, but some might not be. You can try looking at the Viola Jones algo, that did facial detection using HAAR features.

• Image stabilization's impact on individual frames
  reddit.com/r/ImageStabilization | 2021-03-02

  I've recently begun playing around with OpenCV's video stabilization framework—converting my frames into video format, running a stabilizing function, and then extracting the frames again as individual images. This doesn't seem to be working and I guess my question is should this be working? I thought stabilization manipulates the individual frames in a video so shouldn't I be seeing that in my GIF playback?

• OpenCV in Android native using C++
  dev.to | 2021-02-26

  The code is pretty much self-explanatory, the interesting part is bitmapToMat and matToBitmap, these 2 methods, as the name implies, converts between Android Bitmap and OpenCV Mat classes, basically it copies the pixels bytes taking into consideration the pixels format and making the needed conversions. The methods were taken from OpenCV source opencv/modules/java/generator/src/cpp/utils.cpp with some slight adjustments.

• How I compile OpenCV on Linux with lots of bells and whistles (CuDNN, CUDA, OpenGL, Qt, TrueType, Video CODECs)

  You need two projects in order to build OpenCV: the OpenCV source code and OpenCV contrib.

• TIL that you can't use microsoft's new python language server on unofficial builds of visual studio code.

  Thank you for pointing out, I looked into this issue as well. I would just like to add here this issue on opencv's github, the issue's author is asking contributor's/maintainers to add good quality stubs. A lot of other modules are now adding stubs (like numpy). I was talking about this with one of the pyright developers, he too said the same.

• [Question] Is there ArUco Marker Detection support in JavaScript?

  Seems to be supported, but they’re part of the contrib modules which you may not have installed by default. This is likely helpful to you :-)

• [Question] Cascade training GUI for Mac
  reddit.com/r/opencv | 2020-12-31

  From this discussion it seems like the GUI you saw in the video isn't just for windows, but it's not included in more recent versions of opencv (although it's unclear if it should be in the latest ones). Regardless, the discussion suggests the application should be available in opencv 3.4, in which case you might be able to use it from there.
