摘要

Feature extraction is an important part of the document retrieval. The features of a document are equivalent to the fingerprints of a document, which can be used to characterize and retrieve a document. Document preprocessing and feature extraction make a direct impact on the classification and retrieval of documents. Based on the characteristics of the real estate archives, this paper proposes to use morphological methods to process image and synthesize the paragraph features and local pixel features as the integrated features of the real estate archives.
