Quick access method and realization of high resolution CCD compressed video
Aimed at the access of high resolution CCD compressed video in aerial photography and measurement, a quick access scheme based on document structure is put forward. The access system consists of basic and detail image information. The realization structure of the system is proposed in practical memory. On the one hand, image basic information includes frame number, thumbnail, encoding length and address. Through frame number, image basic information is acquired and quick view is implemented. Furthermore, detailed encoding information can be accessed through related image detailed information. On the other hand, thumbnail displaying method based on wavelet transform is designed. Through above access structure, the whole access design was realized. Through the whole access system of compressed high-resolution CCD data, quick view and access were implemented rapidly and efficiently.
