METHODS FOR DECODING CORRUPT JPEG2000 CODESTREAMS

摘要

The method for the code stream of the digital picture and video that the present invention provides a kind of for decoding coding being destroyed, JPEG2000 code flows have improved error resilience property. The decoding technique is applied to a kind of encryption algorithm, and wherein subregion allows generally for be known in the correlation between partition group among the different spaces region of decoding image, and rule domination from the data in following image. Destroying code stream decoding has improved picture quality, the underlying algorithm (200) forced by observing subregion, the division collection of mistake (202), dependence in analysis and perhaps between partition (204), what is determined a section coded data tracking error divides collection can remedy (206), decode those parts (208). Even if that subregion of part still can be decoded completely or partially in particular zones there are error, according to certain modes or ' the code stream that uses during conversion ' creation.
