Nov 02, 2020 · The code examples are from C++. Most of the tutorials are dedicated to basics C++ OpenCV image processing, people detection from LBP haar cascades to modern deep learning. The tutorials are as well dealing with GStreamer OpenCV integration to be able to stream OpenCV output as a video stream to the web.
OpenCV was designed to be cross-platform. So, the library was written in C and this makes OpenCV portable to almost any commercial system, from PowerPC Macs to robotic dogs. Since version 2.0, OpenCV includes its traditional C interface as well as the new C++ one. For the most part, new OpenCV algorithms are now developed […]

May 14, 2019 · OpenCV: Get image size (width, height) with ndarray.shape When an image file is read by OpenCV, it is treated as NumPy array ndarray. The size (width, height) of the image can be acquired from the attribute shape indicating the shape of ndarray.
To make our OpenCV pipeline run faster, we're going to shrink our image down to 640x480 resolution. This resolution isn't so small that the image quality will be reduced enough to make a difference in detecting objects, but it will make OpenCV process our image much quicker. Another pre-processing step that we will run is a box blur.
