Patent number: 12182895Abstract: A system processes images of documents, for example, identification documents. The system transforms an image of a document to generate an image that represent the document in a canonical form. For example, if the input image has a document that is tilted at an angle with respect to the sides of the image, the system modifies the orientation of the document to show the document having sides aligned with the sides of the image. The system stores user accounts that include user information including images. The system generates a graph of nodes that represent user accounts with edges determined based on similarity scores between user accounts. The system determines connected components of user accounts, such that each connected component represents user accounts that have a high likelihood of being duplicates.Type: GrantFiled: September 19, 2022Date of Patent: December 31, 2024Assignee: Uber Technologies, Inc.Inventors: Tao Luo, Chuang Wu, Jinxue Zhang, Xiaoxiang Ren, Chandan Sheth, Zihe Liu
