• Changed phrasing in a task because the selected crop is random. Changed Your plots should look like the following: to The region that is cropped is randomly picked. Your plots may look like the following:

• Replaced invalid function call. The exercise calls for implementing rotate_batch but the test calls rotate_batch_10_degree_and_crop. Changed the test to call rotate_batch.

• Added a summary (previously marked as todo)

In this exercise you implemented techniques to modify a batch of images

• mirroring
• cropping
• rotation
• adding noise

You learned in which scenarios each of the methods are useful and how > you combine them to get the most out of your dataset.
