Q7 Facial Keypoint Detection is used in computer vision to detect key points on a human face. What is the nature of this task?

Q8 Working on computer vision problems require huge amount of image data. However, when we  have insufficient data, we use image augmentation to create more images from the existing images.
Which of the following methods can be used to perform image augmentation?


Q9 Which machine learning algorithm can be used to perform image classification task?

Q10 The task of image classification is performed by extracting features from the images and feeding them to a predictive model.

Let’s say you are working on an image classification task and you want to predict whether an image contains a car or not. Now from the three images below, which will require the least amount of computation for feature extraction?
