Research And Implementation Of Digital Watermarking Based On Remote Sensing Imagery

As a new high-tech strategic industry, remote sensing industry has played a prominent role in China's military and political, economic and people's livelihood. Geospatial information data is the data base of remote sensing industry and is the constructive resource of infrastructure in China. Its important position should not be underestimated. At the same time, the development and processing of geospatial information and data will be greatly improved, and the quality of remote sensing products will be improved. The overall quality of employees in the cause, it has become the cause of rapid and sound development of remote sensing industry, the primary task is to run the cause of remote sensing industry, the only way. How to improve the quality of remote sensing products has become the urgent need to solve the key issues.In the whole process of remote sensing special product processing, it is necessary to involve many personnel to operate remote sensing image, the operation process is complex and time consuming, and it is hard to avoid fatigue, which can not guarantee the quality of remote sensing special product.Digital watermarking technology is an information security technology that can be applied in the process of remote sensing special product quality monitoring. It can provide quality guarantee for remote sensing products and provide solid and reliable information for remote sensing industry. The theoretical basis. In this paper, the development of remote sensing, digital watermarking at home and abroad as well as the development of digital watermarking remote sensing image of the status quo of the remote sensing image digital watermarking done a general overview. Then the difference and characteristics of remote sensing image and ordinary image are discussed. Based on this, the digital watermark embedding algorithm of the vector file in the special product of spatial domain and transform domain is designed. At last, the paper introduces the software platform of digital watermarking software, including software interface design and background database design, so that readers can better understand the demand and purpose of digital watermarking of remote sensing image.
