Studying of image enhancement shows that the quality of image heavily relies on human visual system. In this paper, we apply this fact to design a new image enhancement method for medical images that improves the detail regions. First, the eye region of interest (ROI) is segmented; then the Un-sharp Masking (USM) is used to enhance the detail regions. Experiments show that the proposed method can effectively improve the accuracy of medical image enhancement and has a significant effect.

Visual Fidelity

This paper provides an overview of the literature on the visual system, placing special emphasis on those visual characteristics regarded as necessary to produce adequate visual fidelity in virtual environments. These visual cues apply to the creation of various virtual environments including those involving flying, driving, sailing, or walking. A variety of cues are examined, in particular, motion, color, stereopsis, pictorial and secondary cues, physiological cues, texture, vertical development, luminance, field-of-view, and spatial resolution. Conclusions and recommendations for research are also presented.

Interdisciplinary Journal

Our newest issue of the Interdisciplinary Journal of Signage and Wayfinding focuses on communication effectiveness at the intersection of consumers’ perception and their experience. This special issue features work from marketing and communication scholars who explore the visual characteristics of signage as they influence evaluations, purchase intentions, detection of omission, and compliance. Given the timing of this issue, it is not surprising that the COVID-19 pandemic provided a highly relevant context in which to study consumers’ perception of visual information. As such, two of the articles presented discuss signage within the context of the global pandemic specifically. Other articles present important research on topics related to sign complexity and consumer perceptiveness.
