We propose an approach for the simultaneous bounding box estimation of multiple organs in vol-umetric CT images. Local eigen-organ spaces are constructed for different types of training organs, and a global eigen-space, which describes the spatial relationships between the organs, is also constructed. Each volume of interest in the abdominal CT image is(More)
A new index is proposed to evaluate danger situation in car following based on the hypothesis that drivers are performing approach detection and deciding braking behavior with change of area of a preceding car on the retina. Based on the index, braking behaviors in car following situation is analyzed. The experimental results of a test driver with a real(More)
In order to develop more effective automatic braking system or other braking support system, comfort of drivers should be taken into account. In this paper, deceleration behaviors of an expert driver in car following will be formulated as an example of comfortable braking behavior. The difficulty of its formulation is how to extract characteristics of the(More)
Deceleration patterns of an expert driver will be formulated as an example of comfortable braking pattern. The difficulty of its formulation is how to extract characteristics of the deceleration behavior. This research focuses on visual control of vehicles in car following. We have hypothesized that driver evaluate risk of collision based on the area change(More)
