Retinal ganglion cells (RGCs) are the bridging neurons that connect the retinal input to the
visual processing centres within the central nervous system. There is a remarkable diversity …

This volume presents an integrated view of how we perceive the spatial relations in our
visual world, covering anatomical, physiological, psychophysical, and perceptual aspects …

Visual stimuli contain a limited amount of information that could potentially be used to
perform a given visual task. At successive stages of visual processing, some of this …

Several image compression standards (JPEG, MPEG, H. 261) are based on the Discrete
Cosine Transform (DCT). These standards do not specify the actual DCT quantization …

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 …

Contrast sensitivity at different positions in the visual field has been measured at various
spatial frequencies using a patch of grating suitably vignetted to give a stimulus localized in …

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 …

Originally published in 1985, this volume presents the proceedings of the 11th International
Symposium on Attention and Performance. With few exceptions, the central emphasis in …

Digital video data, stored in video databases and distributed through communication
networks, is subject to various kinds of distortions during acquisition, compression …

We examined discriminations between small patches of grating that differed in either spatial
or temporal frequency. The patches were presented at contrasts near to detection threshold …
