Overview:
Here are some patterns that we have developed internally and with collaborations with others. There are display setup targets and targets to be used to characterize the detector. We have developed the capability of generating these patterns using MATLAB® software (including the Image Processing Toolbox®) for any pixel array. Please note: All the material on our web site is in the public domain. You are free to use it as you would like. If you do use any of it, a citation would be appreciated, of course.
Future Direction: We are working with industry to develop patterns that are useful for setting up displays, for detecting problems in displays, and for making measurements to characterize displays. We are currently extending the face patterns to cover a broader range of problems.
Patterns on FTP site:
General Patterns: On this site is an entire collection of patterns for most pixel arrays (resolutions). If you need additional pixel arrays, please contact us and we will be happy to generate the pixel arrays you desire. The pattern filespecs are NISTDP02_hhhhxvvvv.ZIP, where hhhh is the number of horizontal pixels, vvvv is the number of vertical pixels in the pattern, and the "DP02" refers to "display patterns set number 2." All the testing patterns are in the PNG format. The collections are in ZIP files. If you have a problem with downloading speed, keep in mind that the size of the collections for the larger pixel arrays can be quite large.
Synthetic Faces: One of the directions we have taken is to explore the use of human faces in the setup and testing of displays to look for subtle performance issues. We have generated somewhat realistic synthetic faces of several pigmentations to be used for this purpose. These face patterns are included with the General Patterns above. The present faces collection consists of nine patterns (see examples to right and below). One pattern contains all the figures in costumes that contain the color scales of the primary and secondary colors as well as the gray scale.
Synthetic Faces Originals: These are the original renderings of the synthetic faces should you wish to incorporate them in your own patterns. The size of these originals is 768x1024.
Natural Scenes: Photographs of picturesque areas mostly in Colorado. NOTE: These photographs have compression artifacts and possibly other artifacts arising from the cameras employed. They are not intended to be used for detailed scrutiny of display performance on a pixel level.
