In this paper, we present FlyBy CNN, a novel deep learning based approach for 3D shape segmentation. FlyBy-CNN consists of sampling the surface of the 3D object from different view points and extracting surface featuressuch as the normal vectors. The generated 2D images are then analyzed via 2D convolutional neural networkssuch as RUNETs. We test our framework in a dental application for segmentation of intra-oral surfaces. TheRUNET is trained for the segmentation task using image pairs of surface features and image labels as groundtruth. The resulting labels from each segmented image are put back into the surface thanks to our samplingapproach that generates 1-1 correspondence of image pixels and triangles in the surface model. The segmentationtask achieved an accuracy of 0.9

The Data Storage for Computation and Integration (DSCI) proposes management innovations for web-based secure data storage, algorithms deployment, and task execution. Its architecture allows uploading, browsing, sharing, and task execution in remote computing grids. Here, we demonstrate the DSCI implementation and the deployment of Image processing tools (TMJSeg), machine learning algorithms (MandSeg, DentalModelSeg), and advanced statistical packages (Multivariate Functional Shape Data Analysis, MFSDA), with data transfer and task execution handled by the clusterpost plug-in. Due to its comprehensive web-based design, local software installation is no longer required. The DSCI aims to enable and maintain distributed computing and collaboration environment across multi-site clinical centers for the data processing of multisource features such as clinical, biological markers, volumetric images, and 3D surface models.
