Emulation on FPGA (Field Programmable Gate Array) is used to cover all possible NoC solutions in a reduced exploration time. Emulation requires multi-FPGA platform as the resources for large NoC is important and cannot be handling by one FPGA. In the same time, SoC community is exploring 3D technology for the next generation of large SoC with 3D NoC, making emulation more complex. This paper presents a case study of the deployment of the 2D NoC structure to 3D. A design flow is proposed for the automatic generation of a NoC targeting 3D on multi-FPGAs. The flow integrates emulation blocks used for the validation and exploration on the NoC. With this automatic aided tool, the designer can evaluate and explore the NoC architecture and extract performances of the NoC regardless of the multi-component platform. One may expect a communication performance improvement using an adapted partitioning of the NoC, as highlighted by the results given in this paper.","PeriodicalId":267290,"journal":{"name":"2012 3rd International Conference on Image Processing Theory, Tools and Applications (IPTA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130835441","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}

Artificial Vision and Image Processing offer appealing potential toward reliable extraction of required information.

All tests were run on IV2 database, with challenging variability and including 3500 to 5000 comparisons by experiment from 315 different people. The followed protocol was established in the first evaluation campaign on 2D-face images using the multimodal IV2 database.

The aim of this work is to perform a registration between dynamic CT and ultrasound (US) images (2D speckle tracking mode). The proposed registration approach is based on a contour to surface scheme, decomposed in four steps: (1) the temporal synchronization of data; (2) the segmentation of the left ventricle endocardial surface from the 3D+t CT data; (3) the segmentation and tracking of the myocardium from the 2D+t US data; (4) the registration of US contour with the CT surface. The originality of the method relies on the use of Fourier descriptors and Dynamic Time Warping (DTW) to handle different spatial and temporal resolutions as well as dissimilar cardiac rhythms between CT and US data.

In this paper, we exploited a scene calibration mechanism for estimating depth from a single image, with emphasis on motorways. The approach incorporates linear perspective depth cue to restore distance information of vehicle(s) from a given image. Based upon the assumption that linear perspective is available in ample amount in structured environments, proposed approach computes 1D projective transformation across ground plane which maps imaged distances to the corresponding real-world distances. Once the homography matrix for 1D projective transformation is available, it can be applied to any point to compute its straight line distance from the reference point. Experimental results show that the proposed approach is computationally efficient and delivers desirably accurate depth estimates; thus, it has been applied to identify over-speedings.","PeriodicalId":267290,"journal":{"name":"2012 3rd International Conference on Image Processing Theory, Tools and Applications (IPTA)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129078955","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 fact, the representation of gestures changes dynamically depending on camera viewpoints. Therefore, the different positions of the user between the training phase and the evaluation phase can severely compromise the recognition process. The proposed approach involves the calibration of two Microsoft Kinect depth cameras to allow the 3D modeling of the dynamic hands movements. The gestures are modeled as 3D trajectories and the classification is based on Hidden Markov Models. The approach is trained on data from one viewpoint and tested on data from other very different viewpoints with an angular variation of 180°. The average recognition rate is always higher than 94%. Since it is similar to the recognition rate when training and testing on gestures from the same viewpoint, hence the approach is indeed view-invariant. Comparing these results with those deriving from the test of a one depth camera approach demonstrates that the adoption of two calibrated cameras is crucial.","PeriodicalId":267290,"journal":{"name":"2012 3rd International Conference on Image Processing Theory, Tools and Applications (IPTA)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115369399","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 aim is to predict the subjective quality scores, known as the mean opinion score (MOS) obtained from human observers. In practice, our metric consists of three stages: first, filtering process is applied to watermarked image in order to generate its filtered image. Second, we use watermarked image and its filtered image in the calculation of the objective metrics as input to a neural network. Third; these metrics are combined using neural network model. The output of this neural network is a single value corresponding to the MOS scores. Experimental results show that combination of objective metrics through the neural network, indeed is able to accurately predict perceived quality of watermarked images.","PeriodicalId":267290,"journal":{"name":"2012 3rd International Conference on Image Processing Theory, Tools and Applications (IPTA)","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116399345","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}

For this reason, an unsupervised parallel clustering method inspired by the Extended SOM (ESOM) powered by a Learning Vector Quantization (LVQ) like algorithm is proposed. Then, its parallel supervised versions is presented to further minimize the quantization error in case proper prototypes of the desired clusters are known. Finally, the GPU implementation of both these methods are illustrated to show how we may support time critical tasks such as real time surveillance, interactive medical diagnosis, and control of dynamical systems. The performance of the GPU implementation is discussed with the help of small examples and realistic processing tasks.","PeriodicalId":267290,"journal":{"name":"2012 3rd International Conference on Image Processing Theory, Tools and Applications (IPTA)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132658887","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}
