Abstract: Disclosed are various embodiments for comparing images of network pages using computer vision to identify changes that have occurred between two versions of a network page. A first plurality of segments in a first image representing a first version of a network page are identified and a second plurality of segments in a second image representing a second version of the network page are identified. It is then determined whether each segment in the first plurality of segments matches a respective segment in the second plurality of segments or vice versa.
