Purpose: We aim at studying intrinsic structures of the intracranial subarachnoid space.Material and methods: Magnetic resonance images were obtained using the SPACE sequence, and the segmentation of the superior intracranial subarachnoid space was performed using geometrical features and a topological assumption of the shapes. Given such segmentation results, we present a method based on a geodesic...
This paper presents a method for fitting a digital plane to a given set of points in a 3D image in the presence of outliers. We present a new method that uses a digital plane model rather than the conventional continuous model. We show that such a digital model allows us to efficiently examine all possible consensus sets and to guarantee the solution optimality and exactness. Our algorithm has a time...
This paper shows an extraction method of a symmetric object for eyeglass face analysis using an active contour model. A contour of eyeglasses hinders a face analysis and synthesis which treats contours of facial parts or partial regions of the face such as eyes, mouth, cheek, eyelid and so on. Methods of active contours extract object contour well. We show an active contour model which is adapted...
