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....

Let’s start by first importing the imread method from the OpenCV library in Python: 1 from cv2 import imread Then proceed to read an RGB image. For this purpose, I have downloaded this image and saved it to disk with the name, Dog.jpg, in a folder called, Images. 1 img = ...
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.
This feature was introduced in ZED SDK version3.4. Using your own calibration will not erase the factory calibration, it will just replace it at runtime if requested using the API. To enable this behavior, you have to specify an opencv calibration file as InitParameters::optional_opencv_calibra...
We then show the image. So this is the harris corner detection method. goodFeaturesToTrack Detection Method The other method to detect corners in Python using OpenCV is the goodFeaturesToTrack() method. So with the same original images shown above, the goodFeaturesToTrack() method gives us the foll...
After converting to JPG, apply additional compression using libraries like Pillow or OpenCV to reduce file size without a significant loss in image quality, which is crucial for web usage. Add Watermarks During Conversion Consider adding watermarks to the images during the conversion process. This ca...
The OpenCV library provides you with various methods out of the box and makes our life much easier when it comes to dealing with recognizing, processing, managing, and editing images. In this article, we will see how to draw a circle on an image with the help of the OpenCV library’s ...
