Jpylyzer tool is a validator and properties extractor for JPEG 2000 Part 1 (JP2) images.
Jpylyzer was designed to cover the following two aspects of quality assurance in JPEG 2000 imaging workflows:
Validation against the JP2 format specifications, which ensures that images are standards compliant. It is also effective for detecting common forms of byte-level corruption.
Validation of image and encoding properties against an institute-specific profile. Jpylyzer doesn’t perform this second type of validation by itself, but its extracted properties can be validated against an external schema that defines the institute-specific profile.
Although other tools exist for these tasks, their ‘validation’ scope is rather limited, which introduces the risk that malformed and badly damaged images will go unnoticed. In addition, quite a few tools exist for extracting properties for this format, but most of these either focus on the JP2 header fields or on the codestream headers. Jpylyzer was designed with the aim of filling these gaps.
