Introduction # In this tutorial, you will learn how to capture and display color and depth images using OpenCV and the ZED SDK in Python.
OpenCV allows a user to create a wide variety of shapes, including rectangles, squares, lines, etc. Python has a built-in line() function, which allows us to add a line to an image, usually a blank one. We create this blank image with numpy. Then using OpenCV, we add our line to ...

when using the cv2.imshow() function to show a video in OpenCV, it will go through a video very quickly, because computers can analyze videos much quicker than we can watch them. This is a good thing
To convert an sl::Mat to a cv::Mat, we provide anslMat2cvMat()function in the OpenCVsample. // Create a sl::Mat object (4 channels of type unsigned char) to store the image.sl::Mat image_zed(zed.getResolution(), MAT_TYPE::U8_C4);// Create an OpenCV Mat that shares sl::Mat...

I have used this funtion on OpenCV lib ver-3.4.0 (cv::cuda::remap()) and it have correctly operated. However, with OpenCV < ver-3.4.0, I have reach an error as shown in the figure below: External Media Please help me fix this bug of input parameters of cv::gpu::rema...
with OpenCV. We simply use if/elif statements. You can add as many if/elif statements as you want or need to check for various events and accordingly take action for each of these events that a user does. This is all that is required to check for multiple events in Python with OpenCV...
