diagnostic and clinical support is performed by using ever improving dICOM image systems. Huge quantity of clinical images are generated from clinical devices with increasing high performance. Nevertheless, extracting useful information from dICOM images for diagnosis as well as integrating information from different data sources is still a complex task. We present eIMES 3d (standing for Evolution Imaging System 3d), a system that supports clinicians for images studies, diagnostic and images reconstruction. the tool has been developed within a project called ReCaTuR for RAre Cancer Network (i.e., Network of Rare Cancer), aiming to define a network for the management, organization anddistribution of medical information. Moreover, it was implemented following the requirements of oncology department of an Italian Hospital. By using eIMES 3d a cancer network data infrastructure has been defined and implemented aiming to integrate information regarding rare and complex diseases. data provided by different departments, external structures and research institutes are used to improve knowledge and to support physicians. eIMES 3d allows (i) full control and management of the data by means of artificial intelligence algorithms;(ii) advanced stereoscopic 3d visualization by using the webGL innovative technology;(iii) sharing of medical data;(iv) distribution of 3d imaging on different output devices (web, TV, mobile);(v) querying the system through a search of the various case studies.

the quality of 3d point cloud captured by a structured light 3d camera, such as the density and accuracy of the points, depends upon the optimal settings of 3d camera exposure time. the fixed exposure time often set manually, may not be effective under the variation of ambient conditions, e.g., surface reflectance and illumination that incur saturation and/or under-exposure. this is especially the case where 3d cameras are to apply to industrial inspection. In this paper, a novel method for automatically determining the optimal exposure time of a 3d camera based on estimating the pixel intensity-shutter time slope is proposed. the experiments verify that a dense yet accurate 3d point cloud can be captured under varying ambient conditions: up to 40% improvement over the manual setting for the density of captured point cloud.

three-dimension (3d) medical images on eHealth can facilitate early diagnosis and treatment planning for physicians anddentists anytime and anywhere. However, high-resolution 3d medical images created from most medical imaging devices are difficult to render interactively with high-quality in real-time on the client side. this paper tackles this problem. It presents a web-based client-server framework that provides apparent processing of high-quality volume rendering in real-time on personal computers and tablets. the framework employs the following technique. While zooming and rotating the volume rendered image, the graphic card on a client-side processes low-quality volume rendering. At the same time, images for performing high-quality rendering are being processed and streamed in from the server. When the interaction stops, the server completes the streaming process andthe client can now display high-quality volume rendering. this would help visualizing 3d medical images in real-time and high-quality on web for fast diagnosis and treatment planning.

this paper aims to provide a comprehensive reference source on depth-based human motion descriptors. Motion description is a challenging problem which became popular with recent advances in 3d computer vision. Our goal is to introduce the main trends in human 3d motion descriptor design and evaluation next to presenting a review of recent methods belonging to three application categories: action recognition, gesture recognition and gait assessment.

the main disadvantages of the traditional tilt photography modeling engine are that the modeling takes a long time, the three-space solution is easy to fail, andthe modeling process requires manual intervention, lack of timely control of the scene, not suitable for the emergency rescue in a race against time. the rapid3d modeling method proposed in this paper improves the timeliness of 3d modeling on the premise of ensuring the modeling accuracy and effect by optimizing each stage of route planning, data acquisition, image preprocessing, aerial triangulation and3d reconstruction, andthe feasibility of the method is verified by experiments.

In this study, a pneumatic microfluidic device was designed and fabricated using an extrusion-based3d printer for insulin detection. Compared to the conventional PdMS-based microfabrication for microfluidic devices, 3d-printed fabrication procedure is timesaving by eliminating molding and bonding steps. the printed material is the flexible, semi-transparent and inexpensive silicone. the monitoring of serum insulin level is important as it enables a much early prediction of the occurrence of type II diabetes when compared to glucose monitoring. the present work provides an effective technical approach to realize the fabrication of low-cost microfluidic devices for efficient reagent mixing in microscale biochemical detection systems.

Image-based localization is one of the most important techniques for autonomous navigation. this paper proposes a 6-doF localization method based on image database and local 3d maps. To perform localization, the image database and local 3d map of each image are collected in advance. By applying a fast place recognition algorithm such as FAB-MAP, an initial position is assumed to be available at a past position of a matched image from the database. then, a 6-doF camera pose is estimated using PnP algorithm by 2d-to-3d matching correspondences in a query image and a local 3d map. the proposed algorithm is demonstrated in real environment.

Interests in advancing 3ddesign and integration have stimulatedthis study of connecting two different silicon dies using an organic interposer. this paper reports some of the challenges encountered by the system and silicon designers during the process of 3d integration. the discussion focuses on ways to improve the efficiency of the design flow, integration and verification of a 3d configuration. By considering the strength and weakness of the silicon and system design environments, the two were used in a complementary manner to achieve the 3d integrateddesign.
