What is the nature of this task? It is a regression problem It is a classification problem It is a clustering problem ArticleVideo Book 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? Image rotation Change colours of the image Change contrast and brightness All of the above ArticleVideo Book Q9 Which machine learning algorithm can be used to perform image classification task? Logistic Regression Support Vector Machine Decision Tree All of the above ArticleVideo Book 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? Image 1 Image 2 Image 3 ArticleVideo Book Thank you for taking our survey.
