In this paper, the characteristics of the medium and long wave infrared images are analyzed. Considering the composition of the infrared radiation, starting from speeding up the algorithm, an infrared image generation method is proposed to get infrared images in different bands. In this method, the theoretical temperature is used to improve the algorithm running speed instead of the actual temperature. The comparison experiment shows that the method proposed in this paper can improve the reality of the simulation, and explore a new method of band expansion for infrared images, which is an effective method.","PeriodicalId":187934,"journal":{"name":"2017 International Conference on Virtual Reality and Visualization (ICVRV)","volume":"1 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":"130128406","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}

Rendering the geometrical components in a VR scene such as complex terrain, dense vegetation, building details etc. is a substantial computation task. Typical scene optimization methods include memory allocation, multi-threading, and Levels of Details (LOD). In this paper we experiment to address the challenge of vegetation rendering using a combination of optimization approaches. Experiments in the Unreal game engine show our approaches’ efficacy. Through parallel rendering, the rendering time is reduced by 50%. With LOD, the rendering speed of the scene has been improved by as much as 25%. The LOD transformation is processed frame-by-frame and is essentially seamless as it carries out an efficient rendering pass. Finally, by using the culling algorithm, and setting the attenuation distance and setting the attenuation range, the rendering efficiency is further optimized.","PeriodicalId":187934,"journal":{"name":"2017 International Conference on Virtual Reality and Visualization (ICVRV)","volume":"63 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":"125107331","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}

In particular, based on the analyses regarding the impact of depth map compression on the quality of synthesized view rendering, we locally classify the coding tree units (CTUs) of depth map into two categories, including synthesized view distortion change (SVDC) based and view synthesis distortion estimation (VSDE) based CTUs. This allows us to dynamically distinguish the rate-distortion optimization process of these CTUs and obtain the synthesized view distortion of the VSDE based ones in a high efficiency way. More specifically, a new interpolation-based distortion estimation algorithm dedicated for VSDE based CTUs is proposed such that the actual view rendering process can be successfully avoided. In this manner, a good trade-off between the rate-distortion performance and computational complexity in depth map compression is achieved. Experimental results show that with our proposed HVSO method, 75% of the computational complexity on average can be saved for the view synthesis optimization process with only 1.6% BD-rate loss compared with the state-of-the-art scheme in the 3D-HEVC platform.","PeriodicalId":187934,"journal":{"name":"2017 International Conference on Virtual Reality and Visualization (ICVRV)","volume":"105 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":"131377350","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}

Simultaneously, by introducing text to speech, speech synthesis and speech recognition (speech to text) APIs, we bring out a novel design of two-way communication system between normal people and hearing-impaired communities.

Before tracking the hand, we always need to find the appropriate region of hand in depth map obtained by the camera. Our system utilizes the segmentation depth information to look for the candidate hand regions, and gets a more accurate hand region with auxiliary RGB information. Even when it is not the nearest part than other body regions, we can also detect the hand region accurately. Therefore we make fewer assumptions about hand detection. Based on this, we track the human hand by fitting a virtual 3D hand model to preprocessed depth maps. We treat this as an optimization problem which needs to seek the parameters to make sure that the energy function can get minimum values. Our energy function combines 3D/2D information with shape prior and kinematic priors, and keeps the frame smooth by adding temporal smoothness constraint. The objective function is solved effectively using Gauss-Newton method. The relevant experiments demonstrate the accurate hand detection and robust hand tracking in our system.","PeriodicalId":187934,"journal":{"name":"2017 International Conference on Virtual Reality and Visualization (ICVRV)","volume":"43 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":"129501041","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}
