In recent years, the clinical treatment of computed tomography (CT) has become an important tool in medical imaging. Usually, we can integrate the computer-aided diagnosis (CAD) system to provide the physician the more reliable vision for preoperative diagnosing and analyzing. In this study, we aim to develop a novel region-based method for segmenting lung and lung tumors by the chest CT, and to obtain...
This paper provides a method for indoor semantic mapping in 3D environment. For indoor environment constructed by numerous planar surfaces, plane features are extracted and classified to build the main structure of indoor scene. To identify and cognize different objects located in indoor scene, both the position information and the color information are used in object classification. After the background...
In this paper, a method for the tracking of fingertip in scenes with complex background is proposed. Our method uses a trinocular stereo vision system, named Digiclops, to capture images and to segment finger blocks. For the case that the finger perpendicularly points to a camera, the fingertip can be rapidly located using a statistic-based method. While for other cases, a robust algorithm for fingertip...
