In addition, if the precision of the system is high, it may be used as a pointing device. We have already proposed a horizontal and vertical head pose estimation method using the 3-D positions of the two pupils and two nostrils, which are obtained from the stereo cameras. In the method, the horizontal and vertical angles of the average vector of the normal vector of the plane including the two pupils and one nostril and that of the plane including the two pupils and another nostril were determined as the head angle. The system showed the measurable ranges of more than plusmn 40 deg in horizontal and 30 deg in vertical. In this paper, we propose the head pose detection method with one camera in order to increase the horizontal range. The 3D positions of the pupils and nostrils are determined by giving the distances among the feature points as restraint conditions. The experimental results showed the measurable ranges of approx. plusmn 45 deg in horizontal and 40 deg in vertical. In addition, the one-camera method indicated high resolution compared to our previous stereo method. Finally, the proposed one-camera method was introduced into each of the two stereo-calibrated cameras, placed with 30 deg separated. The two-camera system showed a wide horizontal range of plusmn 60 deg.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132306750","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}

The engine, called EnCIMA (engine for collaborative and immersive multimedia applications), enables a quick development process of applications by providing a high level interface, which has been implemented using the C++ object-oriented programming paradigm. Important characteristics of the engine are the integration of several real time graphics techniques needed by visualization applications; access to network connection management to support collaboration; 3D sound capability; the support to various specialized interaction equipments such as 3D mice, haptic devices, 3D motion trackers, data-gloves, joypads, force feedback joysticks, and; the capacity to have rendering computation and Physics simulation assigned to GPUs and PPUs, respectively. The engine also enables the developer to choose how the scene should be rendered to, i.e. using standard display devices, stereoscopy, or even several simultaneous projection for spatially immersive displays. As part of the evaluation process, we have compared the performance of EnCIMA to a game engine and two scene graph toolkits, through the use of a testbed application.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131724592","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}

Unfortunately, image-based algorithms for granulometry analysis are difficult to tune and validate. In a typical setup, one or more cameras acquire images of a scene with a great number of objects or particles that must be measured. The distribution of the sizes/shape characteristics of the elements are the common output of such systems. The creation of supervised image database where the coordinates of all elements are known is very important and it allows for testing in a suitable manner the final size/shape distribution of particles produced by the image processing system with respect to the real distribution. Due to the great amount of objects or particles in the images, it is not often convenient, or even impossible, to individually measure each single objects in order to test the capability of the image processing system to locate and measure the elements (creation of a supervised dataset). One possible solution encompasses the creation of a synthetic image dataset where the position of each elements is known a priori. In this paper we propose a virtual environment to create and test an image-based granulometric system based on the 3D engine Blender. Results are encouraging and show the effectiveness of the proposed method.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131803328","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}
