An information processing apparatus includes an acquisition unit that acquires, from a terminal apparatus, control information including model identification information for identifying a model of the terminal apparatus and setting information concerning display setting of a screen of the terminal apparatus; and a controller that causes a screen on which fewer display items than an ordinary screen are displayed to be displayed on a display in a case where the model identification information included in the control information indicates a specific model or in a case where the setting information included in the control information indicates specific setting.

Ingeniously contrived construction, strange interlocking shapes, mind-boggling arrangements: 48 outrageously complex Op Art patterns will challenge even the most experienced colorists. Each illustration can be repeatedly printed from the accompanying CD-ROM.

Object tracking is important in various applications such as video surveillance systems, video annotation systems, and human interaction classification systems. Occlusion and noise are the most significant problems in object tracking. In order to overcome these problems, I introduce the temporal spatio-velocity (TSV) transform, which extracts pixel velocities from image sequences. The TSV transform appends the velocity axes to the image sequences and separates occluding objects based on their velocities. The TSV transform is derived from the Hough transform over windowed spatio-temporal images. I present the methodology of the transform and its implementation in an iterative computational form. The intensity at each pixel in the TSV image represents a measure of the likelihood of occurrence of a pixel with instantaneous velocity in the current position. Binarization of the TSV image extracts blobs based on the similarity of velocity and position. The TSV transform provides an efficient way to remove noise by focusing on stable velocities, and constructs noise-free blobs. In this dissertation, I introduce three applications using the TSV transform. The applications are (i) human interaction recognition system, (ii) object tracking system in occluding environments, and (iii) soccer player tracking system. The human interaction recognition system uses side-view image sequences and tracks persons walking on sidewalks. Then it recognizes the interactions between two persons such as "two persons meet from different directions" and "one person follows another person". The system correctly tracks persons and recognizes the interactions between them. The object tracking system in occluding environments tracks moving objects behind static obstacles, such as trees and fences. Although the static obstacles divide moving objects into several pieces both temporally and spatially, the system correctly tracks the objects. The soccer player tracking system tracks soccer players and referees using the ordinary TV broadcasting images. Although the soccer players make complex movements and the camera moves frequently, the system correctly tracks the players and referees.

Over 100 ingeniously constructed designs form dazzling optical illusions and geometric shapes, offering ample opportunities for imaginative and inventive coloring. This compilation consists of 4 volumes that are popular with colorists of all ages: Geometrical Design Coloring Book, Visual Illusions Coloring Book, Optical Illusions Coloring Book, and Dazzling Designs Coloring Book.

With this book you can enter a realm of dazzlingly deceptive designs that offer wonderful opportunities for imaginative and inventive coloring. You''ll find a host of ingeniously contrived constructions, strange, interlocking shapes and mind-boggling arrangements that defy reality and challenge the imagination to grasp their form and structure. Optical illusions are always fun to look at; coloring these masterly mind-bending illusions will add an extra dimension of enjoyment and foster a new appreciation of mysterious pictorial puzzles that make us wonder if seeing is truly believing.

Results of the PZT observations at the ILOM and the USNO based on a common star system (MC3) are studied from non-tidal geophysical points of view. Relative displacements of Mizusawa to Washington, which are derived from residuals of time and latitude are compared with Minster and Jordan''s plate motion (1978). Differences of optical observations between Mizusawa and Washington show a secular variation associated with a periodic variation over a 4 year period. The secular variation shows a similar direction as that of Minster and Jordan''s plate motion. But the magnitude of the optical observation is found to be larger than that of the plate motion derived by Minster and Jordan.
