how openCV library is used

[dreamyt]

don't see any openCV import, could you explain how openCV functions are used in this project? Thanks

Hi. OpenCv is called using import cv2 and only used in the CNN model code as below:

# Show the images using OpenCV and making random selections.
for num in np.random.choice(np.arange(0, len(test_labels)), size=(5,)):
	# Predict the label of digit using CNN.
	probs = clf.predict(test_img[np.newaxis, num])
	prediction = probs.argmax(axis=1)

	# Resize the Image to 100x100 from 28x28 for better view.
	image = (test_img[num][0] * 255).astype("uint8")
	image = cv2.merge([image] * 3)
	image = cv2.resize(image, (100, 100), interpolation=cv2.INTER_LINEAR)
	cv2.putText(image, str(prediction[0]), (5, 20),cv2.FONT_HERSHEY_SIMPLEX, 0.75, (0, 255, 0), 2)

	# Show and print the Actual Image and Predicted Label Value
	print('Predicted Label: {}, Actual Value: {}'.format(prediction[0],np.argmax(test_labels[num])))
	cv2.imshow('Digits', image)
	cv2.waitKey(0)
