Abstract
The present application relates to an image processing apparatus and a method for matching and combining two documents with at least some overlap area. Layout features are extracted from the two documents and used to determine common layout areas of the first and second documents, where the common layout area has the same layout in the first and the second documents. Text data in the common layout areas of the first and second documents are also detected and used to determine common text data of the first and second documents, where the common text data is the same in the first and the second documents. Feature points are extracted from the common layout areas of the first and second documents based on the common text data and the first and second documents may be combined based on the feature points.
