Generating imitation custom artwork by simulating brush strokes and enhancing edges

Abstract: The precision of an initial image is reduced through image automatic processing in a manner simulating techniques used in the production of a custom art work. The resulting image, although generated without human intervention, has a pleasing, customized appearance which can be desirable to consumers seeking decorative art work. One way of reducing the precision of the initial image is modifying portions of the image to have more uniform luminance, color saturation, or color hue, producing a resulting image appearing to contain brush strokes. Alternatively, the precision of the initial image is reduced by locating contrast edges in the image, and modifying the luminance along these edges, producing a resulting image in which objects and features are outlined and have an enhanced definition from the background.

Autonomous evolution of dynamic gaits with two quadruped robots

Abstract: A challenging task that must be accomplished for every legged robot is creating the walking and running behaviors needed for it to move. In this paper we describe our system for autonomously evolving dynamic gaits on two of Sony's quadruped robots. Our evolutionary algorithm runs on board the robot and uses the robot's sensors to compute the quality of a gait without assistance from the experimenter. First, we show the evolution of a pace and trot gait on the OPEN-R prototype robot. With the fastest gait, the robot moves at over 10 m/min, which is more than forty body-lengths/min. While these first gaits are somewhat sensitive to the robot and environment in which they are evolved, we then show the evolution of robust dynamic gaits, one of which is used on the ERS-110, the first consumer version of AIBO.

Nitride semiconductor, semiconductor device, and method of manufacturing the same

Abstract: Provided is a nitride semiconductor having a larger low-defective region on a surface thereof, a semiconductor device using the nitride semiconductor, a method of manufacturing a nitride semiconductor capable of easily reducing surface defects in a step of forming a layer through lateral growth, and a method of manufacturing a semiconductor device manufactured by the use of the nitride semiconductor. A seed crystal portion is formed into stripes on a substrate with a buffer layer sandwiched therebetween. Then, a crystal is grown from the seed crystal portion in two steps of growth conditions to form a nitride semiconductor layer. In a first step, a low temperature growth portion having a trapezoidal-shaped cross section in a layer thickness direction is formed at a growth temperature of 1030° C., and in a second step, lateral growth predominantly takes place at a growth temperature of 1070° C. Then, a high temperature growth potion is formed between the low temperature growth portions. Thereby, hillocks and lattice defects can be reduced in a region of the surface of the nitride semiconductor layer above the low temperature growth portion.

Display apparatus and display method

Abstract: An adequate display operation control in accordance with the external world situation is realized For example, where a user wears the wearing unit of a spectacle-shaped or head-worn unit, the user is made to be able to view any type of image on the display section immediately in front of the eyes, and provided with taken images, reproduced images, and received images At the point, a control relative to various display operations such as on/off of the display operation, display operation mode, and source chage is carried out based on external world information

Human face tracking system

Abstract: A video camera system with autonomous target tracking sets a measuring frame on an object with high accuracy using a hue signal and a brightness signal without being affected by intensity and direction of the light source. A display screen is divided into divided areas and for each divided area, a lightness divided area in which the values of the brightness signal are within prescribed ranges of luminance and a skin color divided area in which the values of the hue signal are within prescribed ranges corresponding to skin color are extracted. Based on the extraction result, the position of the object on the screen determined and the measuring frame is set without being affected by intensity and direction of the light source. Thereafter, the object is continuously centered within the measuring frame.
