How to decode the JPEG2000 codestream destroyed

摘要

A code stream is destroyed for video and digital images encoded, in particular, the present invention provides a method for decoding the JPEG2000 code stream with error tolerance improved properties. Decoding these techniques, in order to enable the decoding of the different spatial sections of the image is typically apply data from the base image is divided into a class of coding algorithms. In addition, the dependence of the split set of multiple rules governing the dependence of the split between sets is known in some cases. Code stream is destroyed, is decoded to include image quality was improved by the following steps. A this stage, step 200 to observe the division imposed by the basic algorithm, step 202 to detect errors of the divided set, dependencies and division in these steps of analyzing the dependence of the split between some cases 204 is a step 208 for decoding those sections and step 206, to determine which can be recovered sections of the encoded data following the error of the divided set. Even if there is an error in the division in a particular example, that mode is used during the generation of the code stream by "switch", part of the division, may be decodable partially or completely still no.
