Yes,
ofxCvColorImage data seems to be like rgbrgbrgb... of unsigned char.
https://openframeworks.cc/documentation/ofxOpenCv/ofxCvColorImage/
so you may get good result by doing pixels.setImageType(OF_IMAGE_COLOR);
before converting to ofxCvImage.
But I recommend not to use it unless the image is small and frequency is low enough because it's slow.
If I were you, I would use OpenCV functionality to convert.
I'm not OpenCV expert but as far as I know you can convert image data using cv::Mat::convertTo
or something like that.
You can check the format of receiving image in getOfPixelFormatFromFourCCType
https://github.com/nariakiiwatani/ofxNDI/blob/master/src/ofxNDIFrame.cpp#L122
Hope it helps!
Oh yes, thanks a lot! This -> pixels.setImageType(OF_IMAGE_COLOR); works for now.
can be closed.
Hello,
I'm trying to use the received NDI image and use it with OpenCV.
It seems like the pixel format is different (I get a lot of lines in the image) and I can't figure out what to do.
looks like this: https://forum.openframeworks.cc/uploads/default/original/2X/f/f0159bd88b523ab3f3ff3d0e8eebc7400808e513.png Do you have a hint, how to convert the ofxNDIVideoGrabber image to an ofxCvColorImage?
Thanks for your help!
