The authors assessed whether parafoveal perception of emotional content influences saccade programming. In Experiment 1, paired emotional and neutral scenes were presented to parafoveal vision. Participants performed voluntary saccades toward either of the scenes according to an imperative signal (color cue). Saccadic reaction times were faster when the cue pointed toward the emotional picture ...

The aim of this paper is to outline the issues involved in the application of machine vision to the automatic extraction of watermarks from paper samples. The correct identi cation and localisation of watermarks is a key issue in paper manufacturing. As well as requiring the position of the watermark for defect detection and classi cation, it is necessary to insure its position on the paper pri...

Pleasant, neutral, or unpleasant pictures appeared for 150 ms in either peripheral or foveal vision, with or without a concurrent foveal load task. Participants indicated whether the visual scene in the picture was or was not pleasant, or was or was not unpleasant. The manipulation of picture location (foveal vs. peripheral) aimed to tap spatial attention, while the perceptual load task was use...

In order to assure appearance quality of an industrial product, sensory inspection by human vision (visual inspection) is implemented in many manufacturing industries. This study focuses on the fact that the frequency of occurrence of defective products varies each time in production processes, and also considers the relationship between the mixing rate of the defective product and defect detec...

The analysis of spatial structure, ie, the encoding of relative positions between pattern elements, was studied in central and eccentric vision. In a two-alternative forced-choice task the observer had to discriminate between two patterns consisting of short line segments. At each trial the two patterns were flashed for 140 msec and the observer indicated whether the patterns were identical or ...
