Software Downloads

Some of the downloadable software developed by researchers at HP Labs, along with several open source projects that originated here.

One way we try to get our work out into the world is by providing downloadable software. Review the software below and download any that you find of interest or value.

ToggleDigital content management

  • DSpace - an institutional digital repository created by HP Labs and MIT Libraries

ToggleHandwriting recognition

  • LOCO-I/JPEG-LS Software - a software implementation of JPEG-LS, the ISO standard for lossless and near-lossless compression of continuous tone images
  • Polynomial Texture Mapping (PTM) software - a new method for increasing the photorealism of texture maps
  • Lipi Toolkit (LipiTk) - a generic toolkit for online Handwriting Recognition (HWR), and packages HWR tools and algorithms with standard ink representations and HWR application interfaces. The toolkit is designed to support different sets of users, with different requirements.

  • Itsy - The Itsy pocket computer is a flexible research platform. Its aim is to enable hardware and software research in pocket computing. It is a small, low-power handheld device with a highly flexible interface, designed to encourage the development of innovative research projects, such as novel user interfaces, new applications, power management techniques and hardware extensions. The information we are making available includes the hardware specifications, a low level monitor, and the Linux source code for the Itsy.
