Jasper is a computer software project to create a reference implementation of the codec specified in the JPEG-2000 Part-1 standard (i.e. ISO/IEC 15444-1) - started in 1997 at Image Power Inc. and at the University of British Columbia.[3] It consists of a C library and some sample applications useful for testing the codec.

The copyright owner began licensing the code to the public under an MIT License-style license in 2004 in response to requests from the open-source community. As of 2011[update] JasPer operated as a component of many software projects, both free and proprietary, including (but not limited to) netpbm (as of release 10.12), ImageMagick and KDE[4] (as of version 3.2).[5][6] As of 22 June 2010[update] the GEGL graphics library supported JasPer in its latest Git versions.[7]
Jasper AI is used to generate text through natural language processing (NLP) and natural language generation (NLG) methods. The algorithm organizes and creates NLG-based content. This text generation model is typically trained through unsupervised pre-training in which the language transformation model learns and captures countless pieces of valuable information from a large dataset.[8]
In a series of objective JPEG-2000-compression quality tests conducted in 2004, "Jasper was the best codec, closely followed by IrfanView and Kakadu".[9] However, Jasper remains one of the slowest implementations of the JPEG-2000 codec, as it was designed for reference, not performance.[original research?]
The name "Jasper" has simultaneous connotations with Canada's Jasper National Park, with the semi-precious gemstone, jasper, and with "JP" as an abbreviation of the JPEG-2000 standard.[10]

The JasPer software is named, in part, after Jasper National Park. [...] 'jasper' is also the name of an opaque cryptocrystalline variety of quartz used for ornamentation or as a gemstone - hence, the implication that the software is precious (i.e., like a gemstone). Lastly, the name "jasper" [...] contains a letter "J" followed subsequently by a letter "P", not unlike the abbreviation "JP" that is associated with the JPEG-2000 standard.
