Pictorial information processing relies heavily on the establishment of an efficient pictorial database system. Presentday database management systems are designed primarily for efficient storage, retrieval and manipulation of alphanumeric data. U ntiI very recently, little attention has been paid to the storage, retrieval and manipulation of non-alphanumeric information such as digitized image...

Emotional stimuli tend to capture attention, and this so-called motivated attention is commonly measured using the early posterior negativity (EPN) and the late positive potential (LPP). We hypothesized that voluntary, directed attention reduces motivated attention more strongly for highly than moderately arousing pleasant or unpleasant pictures. Participants were instructed to direct their att...

The question of object-picture recognition has received relatively little attention in both human and comparative psychology; a paradoxical situation given the important use of image technology (e. g. slides, digitised pictures) made by neuroscientists in their experimental investigation of visual cognition. The present review examines the relevant literature pertaining to the question of the c...

We devised criterial recollection tests to investigate why testing memory for pictures elicits lower false recognition than testing memory for words. Subjects studied unrelated black words paired either with the same word in red font, a corresponding picture, or both. They then took three memory tests, always using black words: a recognition test (say ‘‘yes’’ to all studied items), a red word-t...

In this paper we present the concepts of drawn symbolic picture and symbolic picture. Such notions have been conceived as an extension of the concept of drawn pictures which was introduced by Maurer, Rozenberg and Welzl [31]. We provide a string description of such pictures. It consists of alternating words, i.e. strings whose letters are in alternation from an alphabet of symbols and an alphab...

Automatic image tagging has been a long standing problem, it mainly relies on image recognition techniques of which the accuracy is still not satisfying. This paper attempts to explore out-of-band sensing base on the mobile phone to sense the people in a picture while the picture is being taken and create name tags on-the-fly. The major challenges pertain to two aspects ”Who” and ”Which”. (1) ”...

Traditional deductive systems work with sentences of symbols. Even in newer systems that also reason from diagrams sentential representations still play a major role. The work here explores deductive systems that use only picture-like representations. Machinery functionally equivalent to variables, quantifiers, substitution, unification, and binding are defined based on a model of deductive cha...

Figure 1 Upper two pictures and lower left picture: multiple urothelial cracks seen after hydrodistension, lower right picture: glomerulation (petechiae).

Participants categorized left- and right-pointing line drawings presented together with pictures, whose pointing direction (to the left or right) was ambiguous (spatially ambiguous pictures; Experiments 1 and 2) or that pointed neither to the left nor to the right (spatially neutral pictures; Experiment 3). Subsequently, the spatially ambiguous and neutral pictures were used in a Simon task, wh...

The current study used the process dissociation procedure in conjunction with a stem-completion priming task to disentangle the influences of aware and unaware perception in patients with hemispatial neglect. One lateralized picture prime was presented simultaneously with a filler picture followed by a centrally presented word stem. In the inclusion condition participants were asked to complete...
