NIST CD Compliance Test software

The NIST CD compliance test is designed to test CD-ROM, CD-R, CD-RW and DVD-ROM drives for MultiRead Compliance as specified by the MultiRead specifications developed by OSTA for CD-R and CD-RW discs. MultiRead is described by OSTA as the ability of any drive to read all of the following types of media: CD-DA, CD-ROM, CD-R and CD-RW. The NIST CD Compliance Test is designed to test the drive only for CD-R and CD-RW since it is not capable of making CD-ROM or CD-DA discs. While the NIST CD Compliance Test software supports the MultiRead specification developed by OSTA (as specified by the documentation provided on the OSTA website), the NIST CD Compliance Test software is no way endorsed by or an endorsement of OSTA or any of its products.

NIST Image Comparator

The NIST Image Comparator is designed to demonstrate the NIST Just Noticeable Difference (JND) metric (JND-DCT). JND-DCT is a computed image quality metric, designed to measure the difference between two images, as perceived by a human viewer.The JND-DCT model is based on adaptations found in human vision, including those to luminance, spatial frequency, local contrast, and contrast masking.The model is based on the work of Watson, Ahumada, and Peterson (NASA, Ames) and of Libert and Fenimore (NIST). The model is the subject of continuing research to extend the range of imagery to which it applies.

NIST Digital Cinema Test Patterns and Image Viewer

In the recent (June 2001) MPEG digital cinema compression tests, two display systems were used, with differing interfaces and image formats. The IEC and VESA projector measurement standards are employed in a slightly extended sense to characterize the display systems. Two sets of test patterns were used: one for the DLP and one for the G90. Each set of patterns were stored and played out using the same system components that were employed for the subjective viewing tests. For a comprehensive discussion of the measurements used in characterizing the projection systems used in the MPEG tests see the NIST Interim Report [3].
