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 …

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

A theory of edge detection is presented. The analysis proceeds in two parts.(1) Intensity
changes, which occur in a natural image over a wide range of scales, are detected …

Psychophysics is a lively account by one of experimental psychology's seminal figures of his
lifelong scientific quest for general laws governing human behavior. It is a landmark work …

We measured the spatial frequency contrast sensitivity of cells in the primate striate cortex at
two different eccentricities to provide quantitative statistics from a large population of cells …

Most vision research embracing the spatial frequency paradigm has been conceptually and
mathematically a one-dimensional analysis of two-dimensional mechanisms. Spatial vision …

Shannon's rate-distortion function provides a potentially useful lower bound against which to
compare the rate-versus-distortion performance of practical encoding-transmission systems …

The majority of the research related to visual recognition has so far focused on bottom-up
analysis, where the input is processed in a cascade of cortical regions that analyze …

Contrast masking was studied psychophysically. A two-alternative forced-choice procedure
was used to measure contrast thresholds for 2.0 cpd sine-wave gratings in the presence of …

Image quality can be defined objectively in terms of the performance of some"
observer"(either a human or a mathematical model) for some task of practical interest. If the …
