abstract

  • Pre-compensation of display images in computers can enhance the interaction of computer users with visual impairments and computers. However, the pre-compensation process reduces the contrast of the images perceived by the user, when the pre-compensated images are presented in display devices with limited intensity levels. Therefore, the helpfulness of the pre-compensation process is reduced by the accompanying contrast loss. This paper proposes a side-trim histogram correction method aiming to improve the contrast of the image perceived by the user after pre-compensation has been performed. The side-trim method is based on the analysis of the histogram of the pre-compensated image, in which the trimming process is performed automatically, without manual intervention. © 2013 Springer Science+Business Media.
