In this paper, we propose a shape reconstruction and image restoration method for paper documents with curved surfaces or fold lines by using a stereo vision system. Characters in images of thick book’s pages acquired with an image scanner are difficult to recognize because they are deformed under the influence of curved surface. Therefore, 3-D shape(More)
This paper describes a method for removing adherent noises from image sequences. In outdoor environments, it is often the case that scenes taken by a camera are deteriorated because of adherent noises such as waterdrops on the surface of the lens-protecting glass of the camera. To solve this problem, our method takes advantage of image sequences captured(More)
Colors of objects observed in underwater environments are different from those in air. This is because the light intensity decreases with the distance from objects in water by light attenuation. Robots on the ground or in air usually recognize surrounding environments by using images acquired with cameras. The same is/will be true of underwater robots.(More)
In this paper, we propose a new method that can remove view-disturbing noises from images of dynamic scenes. One of the thorny problems in outdoor surveillance by a camera is that adherent noises such as waterdrops or mud blobs on the protecting glass surface lens disturb the view from the camera. Therefore, we propose a method for removing adherent noises(More)
In this paper, we propose a new method that can remove view-disturbing noises from stereo images. One of the thorny problems in outdoor surveillance by a camera is that adherent noises such as waterdrops on the protecting glass surface lens disturb the view from the camera. Therefore, we propose a method for removing adherent noises from stereo images taken(More)
Map information is important for path planning and self-localization when mobile robots accomplish autonomous tasks. In unknown environments, however, mobile robots should generate an environment map by themselves. We propose a method for 3D environment modeling by a mobile robot. A 3D environment model can be generaterd from the result of 3D measurement(More)
OBJECTIVES Dendritic cell (DC) therapy frequently induces a measurable immune response. However clinical responses are seen in a minority of patients, presumably due to insufficient expansion of antigen-specific cytotoxic T lymphocytes (CTLs) capable of eradicating tumor cells. To increase therapeutic efficacy of DC-based vaccination, we have undertaken the(More)
Recent progress has been made in understanding the mechanisms of antitumor immune responses, which may further clarify the immune status of cancer patients. In this study, we performed a detailed evaluation of the immunological status of 47 patients with advanced solid cancer, who had received no immunosuppressive treatment, and compared the results with 32(More)
When mobile robots execute autonomous tasks, map information is important in path planning and selflocalization. In unknown environments, mobile robots must generate their own environmental maps. This paper proposes three-dimensional (3D) environment modeling by a mobile robot. The model is generated from results of 3D measurement and texture information.(More)
