Spatial resolution is an important factor for human pattern recognition. In particular, low resolution (blur) is a defining characteristic of low vision. Here, we examined spatial (field of view) and temporal (stimulus duration) requirements for blurry object recognition. The spatial resolution of an image such as letter or face, was manipulated with a low-pass filter. In experiment 1, studying...

In traditional database use it is often desirable to extract a particular “view” or subset of the data in order to work on a particular problem. After the work on the view is completed, the problem becomes how to replace this view, and the modifications made, back in the original main database. The same problem arises in the field of spatio-temporal data in a GIS, where not only do we have desi...

We represent an appearance-based technique for detecting multi-view faces. Multi-view face detection has been a challenging problem. It is due to the fact that the distribution of multi-view faces in the feature space is more dispersed and more complicated than that of frontal-view faces. Our system can detect faces under any degrees of pan rotation. This system is composed of two subsystems. O...

In this paper we describe a new method for detecting and tracking multiple persons with a stereo camera. The method is based on the idea of the plan-view map, i.e., the 2D histogram of projected 3D measurements from the camera. It estimates the statistical feature in an optimal window, e.g., a rectangular region, on the histogram, considering stereo measurement error, human breadth, and height....

Office employees spend a lot of time inside buildings, where the physical conditions influence their wellbeing and indirectly influence their employers’ business performance. With data from a field study conducted in the Netherlands in April to May 2003, we used path analysis to further elucidate the relationship between personal (gender and seasonality of mood shifts), building (view type, vie...

Commercial UNIX window systems are unsatisfactory. Because they are cumbersome and complicated, they are unsuitable companions for an operating system that is appreciated for its technical elegance. Their clumsy user interfaces clutter the view of the operating system. A good interface should clarify the view, not obscure ít. Mux is one window system that is popular and therefore worth studying...
