In this study, we integrated a heuristic and a deep learning-based method using Convolutional Neural Network (CNN) for automatic text extraction from videos. The two independent steps used for text extraction are; candidate text region detection and classification. In first step, rectangular regions were detected that potentially contain text by applying heuristics, which includes morphological processing and geometrical constraints. Then, the obtained candidate text regions were passed through several layers of CNN, that first produced convolutional feature map and then classified the candidate regions into either text or not-text classes. A dataset was prepared by collecting videos from various Turkish channels. 70% of the data was used to train the network while 30% for validation. Experiments showed that our proposed method achieved state-of-the-art performance on our dataset.","PeriodicalId":6611,"journal":{"name":"2019 11th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"16 1","pages":"935-939"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77289009","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 control purpose is to keep system stability around an equilibrium point while the robot is moving towards the desired point. A linearized mathematical model is described to obtain a linearized state space model in order to develop a controller and estimator. The designed controller has implemented on the nonlinear dynamics model of the robot. An optimal linear quadratic estimator has been designed to estimate the states of the system and has been connected to an optimal full state feedback regulator. The simulation results obtained in Matlab/Simulink show that the proposed controller is able to achieve the self-balancing while the wheels rotate towards the set-point position.

In this paper, a Fuzzy Logic Control (FLC) based control strategy is proposed for driving mode selection to operate engine only in required conditions. Besides, a Load Point Selection (LPS) algorithm based on engine’s Brake Specific Fuel Consumption (BSFC) characteristic is used to ensure the engine operation at the efficient region. The proposed hybrid controller algorithm is applied to power-split HEV architecture. The WLTP class-3 drive cycle is used for the validation of the proposed algorithm.
