Architects often use two-dimensional media to represent, visualise, and study the three-dimensional qualities of un-built spaces. Knowledge of pictorial cues is a powerful design tool that can be used to enhance the spatial qualities of built environments. This paper draws from the recent developments in computer graphics (physically based renderings and perceptually based tone mapping techniqu...

Multimedia systems involve the association of various types of information: verbal information presented visually or auditorily, static or dynamic pictorial information, and sound information. In a cognitive approach, integrating this information involves complex processes constrained by properties of the learner’s cognitive system, and especially by the capacity of working memory. This paper, ...

Artists have been looking at the world for thousands of years, and thus paintings and drawings can be considered to form a  -year-old corpus of experimental psychology of perception. Through observation and trial-and-error they have exploited the principles of how our brains interpret the input from the retina, giving priority to only certain regularities of the visual pattern. Thus, a stu...

a University of Waterloo, 200 University Avenue West, Waterloo, ON, N2L 3G1, Canada. Correspondence to Geoffrey T Fong (e-mail: [email protected]). Cigarette packages in most countries carry a health warning; however, the position, size and general strength of these warnings vary considerably across jurisdictions.1 Article 11 of the WHO Framework Convention on Tobacco Control (FCTC) and the Ar...

Three experiments examined the effects of using informative verbal and pictorial cues on participants' abilities to perform visual search. By providing participants with more time to encode the cues than had been used previously, all three experiments revealed long-lasting pictorially cued search advantages that stabilized over time. Experiments 1 and 3 demonstrated that searching for changing ...

In the following sections, we provide additional material for the paper “Active Pictorial Structures”. Section 1 explains in more detail the differences between the proposed Active Pictorial Structures (APS) and Pictorial Structures (PS). Section 2 presents the proofs about the structure of the precision matrices of the Gaussian Markov Random Filed (GMRF) (Eqs. 10 and 12 of the main paper). Sec...

A contextual rescoring method is proposed for improving the detection of body joints of a pictorial structure model for human pose estimation. A set of mid-level parts is incorporated in the model, and their detections are used to extract spatial and score-related features relative to other body joint hypotheses. A technique is proposed for the automatic discovery of a compact subset of poselet...

A definition of pictorial style in terms of distinctive combinations of pictorial devices characteristic of a particular culture or period or the work of an individual artist is proposed. Four kinds of pictorial structure are described: the drawing (spatial) systems, the denotation systems, the mark systems and the attributes systems. Three pictures by Poussin, Rembrandt and the Achilles painte...

Appendicitis is a common disorder which requires careful diagnosis to avoid complications. Ultrasound is being increasingly used for diagnosis because of its ease and simplicity. In this series, a range of abnormal findings are presented, as well as useful teaching points on technique and pitfalls.
