Next, open up a Python file on your attacker machine and name it something likeserver_side.pyand include the following code! We'll start by importing the necessary modules and setting up the ideal parameters: importsocket# For network (client-server) communication.importcv2# For video recording...
In the code below, we use inference.Stream() to read webcam frames and then run inference on each frame using a YOLOv5 model. import cv2 import inference import supervision as sv annotator = sv.BoxAnnotator() def render(predictions, image): classes = {item["class_id"]: item["clas...

Here, we can seehow to extract a specific frame from videoin python. In this example, I have imported a module callednumpy as npandcv2, and then read the file by specifying the path. To give the value of the framecap.set(1, 16)is used. Here, 16 is the number of the frame. ...
In this Python tutorial, we learned how we could code for a simple screen recorder in Python. To sum up the above program, we just create an infinite loop, and inside it, we keep capturing the screenshot and writing its data in the"recording.avi"file that makes a video. Also, to han...
