What is jpylyzer?

Jpylyzer is a validator and feature extractor for JP2 images. JP2 is the still image format that is defined by Part 1 of the JPEG 2000 image compression standard (ISO/IEC 15444-1).

Jpylyzer tells you if a JP2 image really conforms to the format’s specifications (validation). It also reports the image’s technical characteristics (feature extraction).
