As a result, the surface reconstruction of point cloud data is a highly challenging problem. This work proposes a novel method, which improves the surface quality compared with existing methods. Our method combines both the local detailed features and the global topological information during the reconstruction process. To facilitate the feature refinement, we first pre-process the point cloud data by relocating each point, upsampling the point data, and optimizing normals to enhance the features and geometric details. We then identify the topological information by segmenting the geometry and constructing curve skeletons for each part and guide the surface reconstruction with the skeletons by minimal user interaction. We demonstrate the effectiveness of our methods with various examples, where our reconstruction can fill out missing data and preserve sharp features.","PeriodicalId":187934,"journal":{"name":"2017 International Conference on Virtual Reality and Visualization (ICVRV)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133049879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on guided filter enhancing feature extraction of the measured images, the images are divided into different regions according to different properties of the material, and the infrared simulation images of the middle time are obtained by feature prediction and fusion. The experimental results show that the infrared enhancement image of the building object which is generated by this algorithm is consistent with the change of the enhanced image, whether it is from the subjective visual effect or the gray histogram. What's more, the algorithm effectively avoids the cumbersome data processing in the general simulation, and has an engineering practical value, low computational complexity, good real-time performance.","PeriodicalId":187934,"journal":{"name":"2017 International Conference on Virtual Reality and Visualization (ICVRV)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123177254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many scholars have studied this problem so far, but the results are not satisfactory. In this paper, we propose an end-to-end deep convolutional neural network composed of two parts. The first part is the feature extraction part which consists of 4 convolution layers and 4 pooling layers to extract feature from the halftoning images. The second part is the reconstruction part which contains 4 deconvolution layers to reconstruct the continuous-tone images. A U-Net structure which concatenates the outputs from the feature extraction layers with deconvolution layers is used for better restoring the detail information of the original images.

In this paper, we proposed an effective image feature extracting and matching scheme for Copy-move forgery detection. First, after pre-processing, the overlapped block is slid one pixel each time to detect the host image. Discrete analytical Fourier-Mellin transform is presented to extract the features in each block. Then, locality sensitive hashing is proposed for distinguishing the identical or similar block features in matching step to get the inlier matches. Finally, the geometric operations are presented to better indicate the detected regions. A series of experimental results indicated that the proposed scheme can identify the forgery images and outperforms the state-of-the-art techniques.","PeriodicalId":187934,"journal":{"name":"2017 International Conference on Virtual Reality and Visualization (ICVRV)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115097751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its key feature is that mechanism contains not only geometric shapes but also internal motion structures which can be calculated to adjust geometric shapes of the mechanical parts. Our system consists of two steps: disassemble mechanical object into a group set and pack them within a box efficiently. The first step is to create a hierarchy of possible group set of parts which is generated by disconnecting the selected joints and adjust motion structures of parts in groups. The aim of this step is seeking total minimum volume of each group. The second step is to exploit the hierarchy based on breadth-first-search to obtain a group set. Every group in the set is inserted into specified box from maximum volume to minimum based on our packing strategy. Until an approximated result with satisfied efficiency is accepted, our approach finish exploiting the hierarchy.","PeriodicalId":187934,"journal":{"name":"2017 International Conference on Virtual Reality and Visualization (ICVRV)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113983472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, gesture-based interactive technology mostly uses a single sensor, such as data gloves or Kinect. When using single data gloves, some have the problem of lacking hand displacement information. When using single Kinect, it can't be real-time and intuitive to show the changes in gestures. And when the gestures are blocked, the gesture recognition rate drops. Therefore, multi-sensors based 3D gesture recognition and interaction method is proposed. To achieve the 3D gesture visualization, tracking and recognition. Experiments show the effectiveness of the proposed method.
