title: Improved validation and feature extraction for JP2 (JPEG 2000 Part 1) images: the jpylyzer tool
creators: Johan van der Knijff René van der Ark Carl Wilson
abstract: <p>This paper presents jpylyzer, a dedicated software tool for validation and feature extraction of JP2 (JPEG 2000 Part 1) images. We first discuss the importance of format validation, and show that for the JP2 format, current tools have deficiencies that make their use in a preservation context problematic. We describe the main characteristics of the new jpylyzer software, and provide some case studies that illustrate its utility in operational imaging workflows.</p>
