Embodiment Construction

[0059] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0060] In our daily business activities, we use a large number of documents and forms every day. At the same time, form documents are also widely used in various fields. Usually, people need to manually process form documents. For example, customers need to pay taxes, and librarians need to collect data information contained in paper form documents. Due to the development of Optical Character Recognition (OCR) technology, people have begun to try to extract data information in tables by using standard table images of available data, which can reduce working time and reduce workload. In the business world, utilizing OCR technology can improve the quality of work and can reduce the huge amount of time people spend processing form documents. In many areas where OCR is used, we make the user aware of the target string printed in the ima...

Abstract

The invention relates to a paper hydrologic yearbook digitalization method. A feature fusion method of high complementarity is put forward on the basis of single feature so that the recognition rate is enhanced. The hydrologic process is similar due to the fact that the hydrologic process is influenced by similar seasonal climatic factors and other random factors, i.e. the flow has contextual relevance. In view of the correlation, a later error correction mechanism based on time sequences is also put forward. In other words, error correction processing is performed according to a certain criterion after classifier recognition. The experiment proves that the recognition accuracy can be effectively enhanced by the mechanism and the working efficiency can be guaranteed.

Description

technical field [0001] The invention relates to a paper hydrological yearbook digitization method, which belongs to the technical field of computer image processing technology and hydrology. Background technique [0002] The paper hydrological yearbook records the most basic hydrological test data. These data contain information on the long-term evolution of nature and the impact of human activities, and play an important role in production, scientific research, and social services. In view of the long-term preservation of the hydrological yearbook, the high frequency of use, and the poor preservation conditions, the paper-based hydrological yearbook has gradually begun to be damaged, and once it suffers man-made or natural damage, it will bring irreparable losses. become a pressing issue. The most effective way to protect the hydrological yearbook is to digitally scan and process the hydrological yearbook to form an electronic file. Based on the above problems, the prior ...
