pbfordev / wxopencvcameras Goto Github PK

A picture is more than 1000 words, so I think a screen shot is needed.

Thanks.

Hi, I have fork this project, and build this project under msys2.

You can see my changes here: https://github.com/asmwarrior/wxOpenCVCameras/commits/master

Bacially, I have to tweak the CMakefiles.txt.

BTW: your project is great!

I'm asking this question here because it will be more relevant and as far as I see, you are quite experienced with wxWidgets and OpenCV bridge building because you know wxWidgets well.

I know this is a demonstration, not a real project, but I need to ask some questions to make things a little clearer.

What's the point of leaving the set bitmap task to the main thread? This slows things down even more, and while you can already play with the pixels in wxThread, I believe the method you chose makes it more difficult.
Rather than sending that much info to the Thread, you can send the thumbnails/panels (in this case the Bitmap Panel). Let the wxThread do the job, not main thread.
Also why to choose this method while you can perform pixel operations such as resizing on each attached thumbnail.
For example, you can take the size of thumbnail panels and resize the cv::Mat for each thumbnail.
But the method you use will prevent the user from having different sized instances of the imported frames. That's just one of the reason to get rid of that method.
