We summarize the various strands of research on peripheral vision and relate them to
theories of form perception. After a historical overview, we describe quantifications of the …

Image quality assessment (IQA) has been a topic of intense research over the last several
decades. With each year comes an increasing number of new IQA algorithms, extensions of …

Image fidelity is the subset of overall image quality that specifically addresses the visual
equivalence of two images. This paper describes an algorithm for determining whether the …

Visual perceptual learning through practice or training can significantly improve
performance on visual tasks. Originally seen as a manifestation of plasticity in the primary …

Various visual cues provide information about depth and shape in a scene. When several of
these cues are simultaneously available in a single location in the scene, the visual system …

We developed and tested a powerful method for identifying and characterizing the effect of
attention on performance in visual tasks as due to signal enhancement, distractor exclusion …

More than 20 years ago, Tanner [Ann. NY Acad. Sci. 89, 752 (1961)] noted that observers
asked to detect a signal act as though they are uncertain about the physical characteristics …

Seeking to understand how people recognize objects, we have examined how they identify
letters. We expected this 26-way classification of familiar forms to challenge the popular …

Most theories of visual search emphasize issues of limited versus unlimited capacity and
serial versus parallel processing. In the present article, we suggest a broader framework …

Systematic measurements of perceptual learning were performed in the presence of
external or stimulus noise. In the new external noise method (Dosher, B, & Lu, Z.-L.(1997) …
