The Page Viewer is a stand alone application for viewing page layout and text content of segmentation ground truth and results of page recognition/OCR systems. The natively supported file format is PAGE XML. However, ALTO XML, FineReader XML, and HOCR can be opened as well.
The viewer shows the page layout as a transparent overlay on the document image. Text content and object attributes are displayed as tooltips.
The Page Viewer requires a Java Runtime Environment version 6 or later. Both 32 and 64 bit installations are supported. Supported platforms are: Windows, Linux, and MacOS.
For a complete ground truth editor and result viewer see the Aletheia tool.
