(Here’s a link to […]

So in order to do some serious image processing with the Intel PCSDK, you need OpenCV, and to do that, you need to convert your pictures from Intel PCSDK (PXCImage::ImageData) to OpenCV (IplImage and cv::Mat)and maybe to OpenGL textures, if you want to display them. I’ve seen all kinds of conversions over the internet, and all […]

If you want to do gesture-controlled apps, it’s quite important to give your user visual feedback. Unfortunately, […]
