Anchoring of lightness values by relative luminance and relative area

Relative area and relative luminance combine to anchor surface lightness values.

The anchoring of lightness perception was tested in simple visual fields composed of only two regions by placing observes inside opaque acrylic hemispheres. Both side-by-side and center/surround configurations were tested. The results, which undermine Gilchrist and Bonato's (1995) recent claim that surrounds tend to appear white, indicate that anchoring involves both relative luminance and rela...

A cross- specialty analysis of relative values in the new version of Iranian relative values for physician

Background: The new version of relative values of diagnostic medical services was published in 2014. It was criticized that the previous edition was suffering from an imbalance between relative values related to various specialties and sub-specialties. The main aim of the new edition of the book was to address this problem by providing more balance relative values related to various specialties...

Lightness, brightness, and anchoring.

The majority of work in lightness perception has evaluated the perception of lightness using flat, matte, two-dimensional surfaces. In such contexts, the amount of light reaching the eye contains a conflated mixture of the illuminant and surface lightness. A fundamental puzzle of lightness perception is understanding how it is possible to experience achromatic surfaces as specific achromatic sh...

Peaked Encoding of Relative Luminance in Macaque

RELATIVE INFORMATION FUNCTIONAL OF RELATIVE DYNAMICAL SYSTEMS

 In this paper by use of mathematical modeling of an observer [14,15] the notion of relative information functional for relative dynamical systemson compact metric spaces is presented. We extract the information function ofan ergodic dynamical system (X,T) from the relative information of T fromthe view point of observer χX, where X denotes the base space of the system.We also generalize the in...
