Betting vs Investments
Sports betting can be called an investment, the purpose of which is to make a profit over different time periods.
OpenCV - An open source computer vision and machine learning library. It includes more than 2,500 algorithms, which include both classical and modern algorithms for computer vision and machine learning.

In the previous lesson, we learned how to get a stream of frames from a webcam and apply various transformations to them. Today we will consider a few more useful functions that will help us display important information in the frame.
To write text on an image using the OpenCV Python library, use the putText () method. The use of the function is shown in the following example (source: https://python.org/python-opencv-cv2-puttext-method/).
import numpy as np import cv2 # Create a black image img = np.zeros((512,512,3), np.uint8) # Write some Text font = cv2.FONT_HERSHEY_SIMPLEX bottomLeftCornerOfText = (10,500) fontScale = 1 fontColor = (255,255,255) lineType = 2 cv2.putText(img,'Hello World!', bottomLeftCornerOfText, font, fontScale, fontColor, lineType) #Display the image cv2.imshow("img",img) #Save image cv2.imwrite("out.jpg", img) cv2.waitKey(0)
If you know the shape (width, height) of the text you write on the image, you can place it in the center of the image. The approximate form of the text in the above example is (268, 36). You may have to find the shape of your specific text using Paint or another application.
Object recognition is performed using color segmentation of the image. There are two functions for this: cv2.findContours and cv2.drawContours.
This article details object detection using color segmentation. Everything you need for her is there.
