Modern driver assistance systems such as collision avoidance or intersection assistance need reliable information on the current environment. Extracting such information from camera-based systems is a complex and challenging task for inner city traffic scenarios. This paper presents an approach to combined scene segmentation and object detection using stereo and color information. The extracted...

Geometric reconstruction of the environment from images is critical in autonomous mapping and robot navigation. Geometric reconstruction involves feature tracking, i.e., locating corresponding image features in consecutive images, and structure from motion (SFM), i.e., recovering the 3-D structure of the environment from a set of correspondences between images. Although algorithms for feature t...

One of the most rapidly growing technologies in the cash management industry is the Automated Clearing House ("ACH") system.' The ACH system is the electronic equivalent to the paper check processing system.' The primary benefits of the system, for both banks and their customers, result from reducing the processing time and costs associated with paper check systems! Although other types of elec...

Birth and rearing conditions were evaluated for their effects on pig growth, body composition, and pork quality using 48 barrows during the spring and summer months. Pigs were either farrowed in indoor crates or outdoor huts. At weaning, indoor-born and outdoor-born pigs were randomly allotted to indoor or outdoor treatments for growing/finishing. Body weight data were collected. Pigs were tran...

Abstract The long stay at home during the COVID-19 pandemic implied that most people had to perform all their daily activities home. That raised need for special features related health, safety, and well-being of residents. This study aimed explore essential design measure perception importance by Cairenes (Egypt) construction industry experts further implementation in future as part buyers’ pr...

For reliable navigation, a mobile robot needs to be able to recognize where it is in the world. The aim of this paper is to present a robust vision-based approach to mobile robot localization, which employ visual features in environment in the system. In our approach, the robot does not have to measure its own position precisely and accurately, and rely only to the visual features which could b...

Older adults living in high-deprivation areas walk less than those living in low-deprivation areas. Previous research has shown that older adults' outdoor walking levels are related to the neighbourhood built environment. This study examines inequalities in perceived built environment attributes (i.e., safety, pedestrian infrastructure and aesthetics) and their possible influences on disparitie...

Favorable perceptions of the built and social neighborhood environment may promote outdoor physical activity (PA). However, little is known about their independent and interactive effects on neighborhood-specific outdoor PA. We examined associations of perceived built and social neighborhood environment factors, and their interactions, with objectively-measured neighborhood outdoor moderate-to-...

We consider the problem of autonomous navigation in an unstructured outdoor environment. The goal is for a small outdoor robot to come into a new area, learn about and map its environment, and move to a given goal at modest speeds (1 m/s). This problem is especially difficult in outdoor, off-road environments, where tall grass, shadows, deadfall, and other obstacles predominate. Not surprisingl...

Mayordomo is a multimodal dialogue system designed to interact with an Ambient Intelligence environment implemented in a home. The system can control appliances installed in a house through speech, text and a GUI interface. It also includes a number of additional features, including system access for identified users only, parental control and record of actions carried out by users.
