In Python, OpenCV stores images in NumPy arrays. Since the ZED SDK uses its ownsl.Matclass to store image data, we provide a functionget_data()to convert thesl.Matmatrix into a NumPy array. # Create an RGBA sl.Mat objectimage_zed=sl.Mat(zed.get_camera_information().camera_resolution....
In Python, we can use theKalmanFilterclass from theopencvlibrary to implement this algorithm and predict states. We will define the attributes of an object for this class and assign the necessary matrices. ThemeasurementMatrix,transitionMatrix, andprocessNoiseCovattributes specify the previously discusse...

Detecting shapes, lines and circles in images using Hough Transform technique with OpenCV in Python. Hough transform is a popular feature extraction technique to detect any shape within an image.
In this article, we show how to detect corners in an image in Python using the OpenCV module. OpenCV has algorithms available that can allow us to detect corners in an image. There are 2 main algorithms used in OpenCV for corner detection: the Harris corner detection method and the goodFeat...
In this article, we show how to display a video file in Python using the OpenCV module. OpenCV allow us to perform a number of image and video functions. Using OpenCV, we can display a video file and watch it just like any other video. ...
