Abstract: When repurposing a document, a processor reads a document having multiple pages and extracts three samples of the multiple pages of the document. For each of the three samples, the processor compares sequential pages within a respective sample to identify a pattern of markers, such as page numbers. A marker is found by splitting a page into smaller regions and wherein each smaller region is searched for the marker and if the marker is not found continuing to split a smaller region into further smaller regions. The processor removes the markers based on identified patterns for each respective sample of the document.

Abstract: In one example, a device to display simulated augmented content is described. A computer readable medium includes instructions and a list containing a set of indexes. A processor executes the instructions to receive on the device visual data providing multiple images of a set of unique identifiers on a page of learning material associated with a page index. A set of unique identifier indexes and a set of orientation data for each unique identifier is created. A set of content for the page of learning material is identified. Simulated augmented content using the set of content is generated for display on the device. The orientation of the simulated augmented content is based on the set of content and at least one of the set of orientation data and the set of unique identifiers.
