-====== Object Detection with Tensorflow, OpenCV, ImageAI and YOLO ======
-===== Requirements: =====
-Be sure to have the [[:computer_science:computer_vision:opencv:object_identification_tensorflow_opencv_imageai_yolo_requirements|requirements]] installed.
-===== Project Start - Importing Libraries and Testing =====
-==== Initialize the libraries ====
-<code python>
-import cv2 as cv #Loads ComputerVision / OpenCV
-from imageai.Detection import ObjectDetection as od # Loads ImageAI
-import numpy as np # Imports NumPY
-import requests as req # Imports Requests
-import os as os # Imports OS Module
-</code>
-==== Testing if OpenCV is working: ====
-<code python>
-url = 'https://p7.hiclipart.com/preview/124/937/193/architectural-engineering-engineer.jpg' # Image to be Downloaded
-r = req.get(url) # Pass the URL as a Request.Get
-with open('testimage.jpg', 'wb') as outfile: # Writes the Image to the system
-    outfile.write(r.content)
-img = cv.imread('testimage.jpg') # Reads an image with OpenCV
-window_name = 'image' # Defines a Window Name
-cv.imshow(window_name, img) # Show the Image on a Window
-cv.waitKey(0) # Wait for any Key to be pressed
-cv.destroyAllWindows() # Destroy (all) previous created Windows
-</code>
-==== Preparing for the upcoming project: ====
-Now that we tested that OpenCV is working let's edit that last piece of code, change it to a function, so we can reutilize it often. The complete code until now should look like this:
-<code python>
-import cv2 as cv
-from imageai.Detection import ObjectDetection as od
-import numpy as np
-import requests as req
-import os as os
-def showImage(img):
-    window_name = 'image'
-    cv.imshow(window_name, img)
-    cv.waitKey(0)
-    cv.destroyAllWindows()
-</code>
