What does the “shift” augmentation do to an image?A) Changes the brightnessB) Shifts the image horizontally or verticallyC) Rotates the imageD) Adds noise to the image

With respect to image data augmentation, how does fastai presizing workand why is it advantageous?

Q.4 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?1. Image rotation2. Change colours of the image3. Change contrast and brightness4. All of the above

What are Intensity Transformations? 1 pointUsed for blurringUsed for edge detection Changing an image one pixel at a time None of the above

To increase the contrast of the image           To reverse the blurring effect caused by the imaging system           To remove noise from the image           To enhance the edges in the image

What is the purpose of data augmentation in deep learning? Question 14Answera.  Reducing the learning rate during trainingb.Expanding the training dataset by applying various transformations to the existing datac. Increasing the complexity of the modeld. Adding noise to the data for regularization
