Combining current vision techniques with stereoscopic cameras has benefits that reduce processing expense and increase the suitability of the resultant data. The novel use of stereoscopic imaging centered within a single device allows for extraction of features from dynamic backgrounds where the camera is not bound to a single fixed point and is subject to 6DOF. The System achieves frame rates in excess of 15fps operating on a single 1GHz core mobile device. The device used has a dual core allowing the addition of virtual content for augmentation without affecting the performance of the tracker.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115297902","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}

Their elements are directly used in this paper instead of Haralick features in order to characterize each pixel of the image. The pixels having the same features are then gathered into classes using the Fuzzy C-means algorithm. Experiments results on synthetic and real images show the relevance of the elements of GLAMs in the segmentation of images with different textures.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116415177","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}

Histogram of oriented gradients (HoG) is one of the most effective pedestrian feature extraction approaches to the study. In this paper, an optimization of pedestrian detection based on HOG method is presented and investigated to achieve an accurate human detection system. The study of different computation steps of the standard algorithm shows the possibility of improving the system performance, specifically in the build histograms step. The main idea is to customize each bin weight according to its contribution in the pedestrian extracted features. Actually, the different bins of a HoG improved vector that encodes a single cell will not have the same weight. Indeed, after the histograms computation, we will distribute an amplification factor for each bin in order to increase the weight bins that describe the relevant pedestrian features from a side. Top of that, we were interested to decrease the bins weight that affect the irrelevant features such as, other obstacle or the image background. The classification system is performed using a linear SVM classifier which is simple and easy to implement in ADAS applications. The performance studies using MATLAB simulation, proves the effectiveness of our approach.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123383559","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, these media have been hijacked by people to plan and commit online fraud and societal evils. Some of the secondary and university campuses in Nigeria have been turned to cultist environments leading to killings and anarchy amongst students. This situation has defied solutions in most tertiary institutions in the country, particularly in the public institutions. The objective of this paper is to provide an anti-cultism social media educational system that will be accessed using three modes: Web, Mobile and Voice. The system will support learning and interaction on campus while at the same time helping to curb cultism on campus through filtering of communicated social media keywords that are cultism or crime related, among students. In carrying out this project, appropriate research methods and implementation tools were deployed. The project offers a multimodal platform that will foster and encourage active learners' participation in the school system.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128099891","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 routing protocols for MANETs are designed based on the assumption that all participating nodes are fully cooperative. In such networks, the Selfish behaviour is among the big challenges and can lead to the degradation of the network performance. We'll introduce this behaviour and. We'll propose a new profile to assess the impact on the performance of MANETs: energy, end-to-end delay, routing packets and the packets rate. The Results of simulations using OLSR and AODV protocols have shown that energy-based selfishness is a big problem and could affect the performance in MANETS depending on the mobility of nodes, size and density of the network. We'll try to prove that the selfish behaviour can be used to impact quality of service (QoS) and security in MANETS. Therefore, we need a comprehensive mechanism to cope with this behaviour to isolate selfishness nodes and we have planned to publish it in the future work as a new strategy based on game theory to encourage nodes to cooperate.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115863668","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 this paper, we present a study of the distance type effect on the segmentation result using UHNNC. We have used a database of 1000 sputum color images prepared to be used in a screening process for lung cancer diagnosis. A quantitative comparison between the results obtained using the Euclidian and the Manhattan distance or city block distance showed that the former gives better classification or segmentation to the pixels of the different cells present in the sputum color images.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115962126","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}

Our method permits the creation and capture of virtual stereo scenes in a carefully controlled environment. Stereo image pairs produced by the system can subsequently be used for testing stereo matching algorithms and a large variety of computer vision techniques. Compared to a physical stereo camera setup this virtual method provides significantly finer and a better quantitative control over all variables involved in image acquisition ranging from camera parameters to specific detail of object materials such as texture, colour and reflectiveness including their behaviour under different lighting conditions. This is illustrated in this paper by comparing images produced via this method to those captured with physical stereo cameras in stereo matching tests using OpenCV algorithms.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128365694","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}

Most scheduling techniques are faced with several challenges such as multiple issues, exploiting more parallelism in programs instructions, speedup rate of executions and support for conditional instructions constructs. Recent innovations in memory system and scheduling techniques required support for instruction-level parallelism (ILP) algorithm, which is overlapping of instructions sets for parallel processing and execution. To achieve these, a survey of the widely used techniques for exploiting of instruction-level parallelism (ILP) is carried out to identify their strengths and their weaknesses by reviewing several related works. This paper finds out the limitations of the various techniques for exploiting ILP and used these reviews to propose a new technique to overcome these limitations.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130348745","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}
