Our approach exploits both colour and depth information recorded by a single RGB-D camera to better deal with negative factors such as lighting conditions and lane-like objects. In the approach, colour and depth images are first converted to a half-binary format and a 2D matrix of 3D points. They are then used as the inputs of template matching and geometric feature extraction processes to form a response map so that its values represent the probability of pixels being lane markers. To further improve the results, the template and lane surfaces are finally refined by principal component analysis and lane model fitting techniques. A number of experiments have been conducted on both synthetic and real datasets. The result shows that the proposed approach can effectively eliminate unwanted noise to accurately detect lane markers in various scenarios. Moreover, the processing speed of 20 frames per second under hardware configuration of a popular laptop computer allows the proposed algorithm to be implemented for real-time autonomous driving applications.","PeriodicalId":236488,"journal":{"name":"2018 2nd International Conference on Recent Advances in Signal Processing, Telecommunications & Computing (SigTelCom)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130607653","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 dimensionality reduction was applied to features extracted from an existing pre-trained Deep Neural Network (DNN) structure, the AlexNet. An analysis of the neurons in different layers of the AlexNet revealed an incremental increase in the pair-wise orthogonality between weight vectors of neurons in each layer, towards higher-level layers. This observation motivated the current study to evaluate the possibility of performing randomized dimensionality reduction by mimicking the observed orthogonality property of the high-level layers on activations of low-level layers of the AlexNet. Image object classification experiments have shown that the proposed random orthogonal projection method performed well in multiple tests, consistently outperforming the well-known statistics-based sparse random projection. Apart from being data independent, the proposed approach achieved performances comparable with the state-of-the-art techniques, but with lower computational requirements.","PeriodicalId":236488,"journal":{"name":"2018 2nd International Conference on Recent Advances in Signal Processing, Telecommunications & Computing (SigTelCom)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127646359","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 that optimization of an outer-precoder dimension is consequential for two-stage precoder design with limited feedback. A smaller dimension of the outer precoder is beneficial to both inter-group interference (IGI) cancelation and the amount of feedback, but restricts same-group interference (SGI) cancelation. Based on a lower-bound of the expected signal to interference plus noise power ratio (SINR), we optimize the dimension of an outer precoder to maximize the average sum-rate. Since the derived lower-bound depends only on the channel covariance matrix and the dimension of the outer precoder, the dimension of an outer precoder can be pre-determined at the BS without knowing the instantaneous dimension-reduced effective channel via feedback. Our simulations results show that our proposed scheme achieves near-optimal average sum-rate.","PeriodicalId":236488,"journal":{"name":"2018 2nd International Conference on Recent Advances in Signal Processing, Telecommunications & Computing (SigTelCom)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128633897","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}

Therefore, multi-carrier transmission technique has been proposed to be a robust and efficient technique to transmit data over severe communication channels. The Orthogonal Frequency Division Multiplexing (OFDM) is a very efficient multi-carrier technique that can fulfill high demands of users. This technique has been studied by many researchers, mainly as mean to combat fading and Additive White Gaussian Noise (AWGN). However, in the real communication environment, the main source of additive noise is man-made noise which by its nature is impulsive. Impulsive noise is composed by thermal noises in electronic devices of receivers and incoming electromagnetic impulses from nearby other electrical devices. These kinds of noise inject high electromagnetic energy into receivers so that it strongly affects to quality of received signals. Therefore, in this paper, the performance of OFDM system in the presence of multi-path fading environment and non-Gaussian noise, which modeled by the class A Middleton noise, is illustrated by using the Monte Carlo simulation technique.","PeriodicalId":236488,"journal":{"name":"2018 2nd International Conference on Recent Advances in Signal Processing, Telecommunications & Computing (SigTelCom)","volume":"177 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125763666","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}
