数字图像处理的最新进展为最大化视力受损者的残余视力提供了有前途的方法。本文旨在向读者介绍这一领域,并描述其在文献中发现的现状。一项系统性的搜索显示了37项研究,这些研究测量了图像处理技术对低视力受试者的价值。所使用的技术根据其效果进行分类,并总结了主要结果。对于各种增强类型,大多数参与者更喜欢增强图像而不是原始图像。调整对比度和空间频率内容通常可以提高物体识别和阅读速度的性能,衰减图像背景的技术和引起抖动的技术也是如此。在偏好和业绩衡量方面缺乏一致性,也缺乏独立的研究。尽管如此,有希望的结果应该鼓励进一步的研究,以使其广泛用于低视力辅助设备。
Recent advances in digital image processing provide promising methods for maximizing the residual vision of the visually impaired. This paper seeks to introduce this field to the readership and describe its current state as found in the literature. A systematic search revealed 37 studies that measure the value of image processing techniques for subjects with low vision. The techniques used are categorized according to their effect and the principal findings are summarized. The majority of participants preferred enhanced images over the original for a wide range of enhancement types. Adapting the contrast and spatial frequency content often improved performance at object recognition and reading speed, as did techniques that attenuate the image background and a technique that induced jitter. A lack of consistency in preference and performance measures was found, as well as a lack of independent studies. Nevertheless, the promising results should encourage further research in order to allow their widespread use in low-vision aids.
