Abstract

Digital images are commonly used to represent scientific data. Typically, high resolution images with many square pixels are considered to be necessary under the assumption that the increased precision of such images yields increased accuracy to the viewer. We question this assumption by demonstrating improved accuracy in viewing digital images without requiring increased resolution by demonstrating how pixels with variable shapes chosen to best represent an image constitute a significant improvement over the square pixels in enhancing the accuracy of viewing such digital images.

科学成像的精度和准确性。

数字图像通常用于表示科学数据。通常情况下，高分辨率图像与许多方形像素被认为是必要的假设下，这些图像的精度增加产生增加的精度，以观看者。我们质疑这一假设，通过展示在不需要增加分辨率的情况下观看数字图像的精度提高，通过展示如何选择具有可变形状的像素来最好地代表图像，在提高观看此类数字图像的精度方面构成了比正方形像素的显着改进。

期刊介绍： The Journal of Research of the National Institute of Standards and Technology is the flagship publication of the National Institute of Standards and Technology. It has been published under various titles and forms since 1904, with its roots as Scientific Papers issued as the Bulletin of the Bureau of Standards. In 1928, the Scientific Papers were combined with Technologic Papers, which reported results of investigations of material and methods of testing. This new publication was titled the Bureau of Standards Journal of Research. The Journal of Research of NIST reports NIST research and development in metrology and related fields of physical science, engineering, applied mathematics, statistics, biotechnology, information technology.
