Mosaic plots are state-of-the-art graphics for multivariate categor ical data in statistical visualization. Knowledge structures mathematical models that belong to the theory of knowledge spaces psychometrics. This paper presents an application mosaic psychometric arising from underlying structure models. In simulation trials and with empirical data, scope this graphing method space is investig...

Generating artificial classic mosaics from digital images is an area of NPR rendering that has recently seen several successful approaches. A sequence of mosaic images creates a unique and compelling animation style, however, there has been little work in this area. We address the problem of creating animated mosaics directly from real video sequences. As with any animation, the main challenge ...

The Bulletin for March, 1944, in connection with the Museum's exhibition of reproductions of mosaics uncovered by the Byzantine Institute, published an article by Professor Charles Rufus Morey on the mosaics of Hagia Sophia. The following paper, read in Mr. Whittemore's absence at a recent symposium of Byzantine scholars held at Dumbarton Oaks, deals with some problems brought out in "this char...

Image mosaics are useful for a variety of tasks in vision and computer graphics. A particularly convenient way to generate mosaics is by ‘stitching’ together many ordinary photographs. Existing algorithms focus on capturing static scenes. This paper presents a complete system for creating visually pleasing mosaics in the presence of moving objects. There are three primary contributions. The fir...

The dynamic facial expressions of emotion automatically elicit multifaceted psychological activities; however, the temporal profiles and dynamic interaction patterns of brain activities remain unknown. We investigated these issues using magnetoencephalography. Participants passively observed dynamic facial expressions of fear and happiness, or dynamic mosaics. Source-reconstruction analyses uti...

Automatic segmentation and analysis of ancient mosaic images can help archeologists and experts build digital collections and automatically compare mosaics by means of image database indexing and content-based retrieval tools. However, ancient mosaics are characterized by low contrast colors, irregular tessella shape, orientation and positioning, making automatic segmentation difficult. In this...

This paper presents techniques for constructing full view panoramic mosaics from sequences of images. Our representation associates a rotation matrix (and optionally a focal length) with each input image, rather than explicitly projecting all of the images onto a common surface (e.g., a cylinder). In order to reduce accumulated registration errors, we apply global alignment (block adjustment) t...
