The present paper proposes an image pickup system for coarse integral volumetric imaging (CIVI), which is a 3D display solution combining multiview technology based on integral imaging and volumetric imaging technology using multilayered panels. In order to apply CIVI display system for live action videos, an image pickup system that can obtain not only multiview image but also depth informatio...

In this paper, we aim for detection and segmentation of Arabidopsis thaliana cells in volumetric image data. To this end, we cluster the training samples by their size and aspect ratio and learn a detector and a shape model for each cluster. While the detector yields good cell hypotheses, additionally aligning the shape model to the image allows to better localize the detections and to reconstr...

This paper, based on doctoral research carried out from January 2003 through July 2005, addresses the interpretation and representation of non-Western religious material culture in Western museums and offers a comprehensive view of the way traditional religious Yorùbá objects are displayed in contemporary museums in Britain. Museum exhibitions can be conceived as a visual narrative, which absor...

We propose a real-world-oriented interface called the “Mirror Metaphor Interaction System”. The display shows a mirror image from a camera facing a user, and the user can “touch” objects without making direct contact with the display. The “touched” object displays a menu or works directly. Objects can be placed in a remote room as well as in the user’s room, and can also be moved around in a ro...

We present herein 4D ultrafast ultrasound flow imaging, a novel ultrasound-based volumetric imaging technique for the quantitative mapping of blood flow. Complete volumetric blood flow distribution imaging was achieved through 2D tilted plane-wave insonification, 2D multi-angle cross-beam beamforming, and 3D vector Doppler velocity components estimation by least-squares fitting. 4D ultrafast ul...

This paper describes a novel volumetric image synthesis system and artistic technique, which generate moving volumetric images in real-time, integrated with music. The system, called the Hologlyphic Funkalizer, is performance based, wherein the images and sound are controlled by a live performer, for the purposes of entertaining a live audience and creating a performance art form unique to volu...

In this paper we describe a method of determining the separation plane of two objects during collision detection. This method is specifically designed for volumetric particle representations of objects, volpars. This particular technique offers an advantage over previous methods because it only looks for a separating plane for the areas local to the point of contact. This increases the robustne...

We introduce a new framework for non-linear, non-reconstructive deformation of volumetric datasets. Traditional techniques for deforming volumetric datasets non-linearly usually involve a reconstruction stage, where a new deformed volume is reconstructed and then sent to the renderer. Our intuitive sweep-based technique avoids the drawbacks of reconstruction by creating a small attribute field ...

Background/introduction Many applications of thermal therapy would benefit from temperature distribution measurements with high spatial and temporal resolution that cover a large 3D volume. Although MRI can acquire 3D temperature measurements, it is not possible to obtain fully sampled 3D MRI measurements that cover the insonified field of view with sufficient spatial and temporal resolution fo...

Image segmentation plays a crucial role in effective understanding of digital images, planar or volumetric images. The current research in graph based methods is oriented towards producing approximate solution (or sub-optimal solution) for such graph matching problem to reduce processing time. We are introducing an algorithm for volumetric segmentation based on virtual tree-hexagonal structure ...
