For the texture analysis part, we have used an automatic sampling and a manual sampling to extract statistical features from the MPM texture. For the segmentation stage, the method iterates the whole CT volume and selects pixels satisfying the extracted statistical criteria. The assessment of the proposed method showed an acceptable degree of similarity rate (J=0.73) between the ground truth and the generated MPM volume.","PeriodicalId":259951,"journal":{"name":"2017 International Conference on Advanced Technologies for Signal and Image Processing (ATSIP)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132497436","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}

We show the Direction Of Arrival (DOA) estimation can be realized through the non-unitary joint diagonalization of spatial quadratic time-frequency. We use an approach of selection of time-frequency points to construct the set of matrices which will be jointly diagonalized to estimate the noise subspace. The main advantage of this method is that it does not require any whitening stage, and thus, it is intended to work even with a class of correlated signals. Finally, the noise subspace obtained is then used to estimate the directions using the MUltiple SIgnal Classification MUSIC spectrum. Numerical simulations are provided in order to illustrate the effectiveness and the behavior of the proposed approach.","PeriodicalId":259951,"journal":{"name":"2017 International Conference on Advanced Technologies for Signal and Image Processing (ATSIP)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116300243","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}

From the previous studies, it is inferred that the significant portion of the eukaryotic genomes is composed of transposable elements (TEs). The TEs play an important role as a driving force of genome evolution. An important sub class of ETs class II, Helitrons, have been revealed in diverse eukaryotic genomes. These elements have a remarkable ability to capture genes and they transpose by a rolling circle mechanism. In this context, helitron location is one of the main challenges of cell biology to better understand the different hereditary characteristics transmission modes in genomes. In this paper, we introduce the Frequency Chaos Game Signal (FCGS) method which provides a new way to present the DNA genomic sequence as a DNA signal (1-D presentation). Then, we use the Support Vector Machine (SVM) classification technique to classify helitron DNA. This choice came after studying the performance of SVM technique by varying the parameters of the kernel tricks. For this aim, different kernels have been taken into account. As for the nonlinear SVM approach, we choose the one-against-one strategy.","PeriodicalId":259951,"journal":{"name":"2017 International Conference on Advanced Technologies for Signal and Image Processing (ATSIP)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134595061","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}

Human posture recognition algorithms can help monitor aged people in home environments. Different types of sensors can be used for such a task. A case in point is the RGBD sensors, which are cost-effective and provide rich information about the environment. This work aims to propose a posture recognition approach exploiting skeleton data extracted from Kinect. Our approach is based on the pose prediction using key joints features. We exploit the Convolution Neural Network for pose estimation and a multiclass Support Vector Machine to perform posture classification. The proposed approach has been tested on a publicly available dataset for activity recognition, namely CAD60. Our approach compares favorably previous works for both human pose estimation and posture recognition.","PeriodicalId":259951,"journal":{"name":"2017 International Conference on Advanced Technologies for Signal and Image Processing (ATSIP)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127188116","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 our method, Gabor Wavelets (GW), Local Binary Patterns (LBP) and Binarized Statistical Image Features (BSIF) were combined. Moreover, the dimension reduction was applied in order to minimize the pattern vectors using PCA. Finally, we used KNN-SRC for classification. The introduced technique was assessed on LFW database using several experiments and tested on other databases, such as PUBFIG83, FERET, EXT.YALE B, ORL and IFD, in order to validate our approach.

Riesz wavelet transform is a steerable pyramid wavelet transform. Before Riesz-wavelet decomposition is applied to the noised image; the given coefficients undergo to thresholding technique, where appropriate threshold limit at each level and threshold method (hard or soft thresholding) are used to remove the noise; therefore, the denoised image is obtained by reconstructing thresholded Riesz wavelets coefficients. The performance of the denoising method is analyzed by using computer-simulated correlation fringes, and the results are compared with those produced by discrete wavelet transform thresholding technique.

The complex nature of the land use change process, due to human-nature interactions and the singularities of satellite images, demands a well-studied approach. Yet, a synthesis document is needed to provide a synthetic director paper combining the proposed and/or used models, their advantages and drawbacks. Hence, such studies are required to face the huge demands of land cover changes prediction needs.
