This paper presents a new deformable model using both population-based and patient-specific shape statistics to segment lung fields from serial chest radiographs. There are two novelties in the proposed deformable model. First, a modified scale invariant feature transform (SIFT) local descriptor, which is more distinctive than the general intensity and(More)
Public opinion is needed for making decisions in the public sector. However, the expression of opinion must be responsibly done. In this study, the focus is decision making for advanced and unfamiliar technologies, and a method using communication without explicit interaction to express opinions is proposed. Evaluation experiment was conducted to test the(More)
The authors have developed a performance test, CPTOP (Cognitive Performance Test of Productivity), which combines 11 basic task testss to evaluate intelligent abilities of office workers in order to quantitatively and objectively evaluate their productivity by controlling office environment. However, in the previous experiment, it was found that the results(More)
Nonverbal information, such as that contained in facial expressions, gestures, and tone of voice, plays an important role in human communications (Kurokawa, 1994). Facial expressions, especially, are a very important media for visually transmitting feelings and intentions (Yoshikawa, 2001; Uchida, 2006). At least one study has shown that more than half of(More)

This paper presents a new deformable model using both population-based and patient-specific shape statistics to segment lung fields from serial chest radiographs. First, a modified scale-invariant feature transform (SIFT) local descriptor is used to characterize the image features in the vicinity of each pixel, so that the deformable model deforms in a way(More)
