Segmentation-free detection of overtaking vehicles with a two-stage time-delay neural network classifier
نویسندگان
چکیده
We propose an algorithm based on a time delay neural network (TDNN) with spatio-temporal receptive elds for segementationfree detection of overtaking vehicles on motorways. Our algorithm transforms the detection problem into a classi cation problem of strongly downscaled image sequences which serve as an input to the TDNN without a preliminary segmentation step. The TDNN classi er is followed by an additional classi cation stage to evaluate the TDNN output over time, which achieves a signi cant enhancement of the detection performance especially under di cult visibility conditions.

Modeling and Intelligent Control System Design for Overtaking Maneuver in Autonomous Vehicles
The purpose of this study is to design an intelligent control system to guide the overtaking maneuver with a higher performance than the existing systems. Unlike the existing models which consider constant values for some of the effective variables of this behavior, in this paper, a neural network model is designed based on the real overtaking data using instantaneous values for variables. A fu...
متن کاملA multi-scale convolutional neural network for automatic cloud and cloud shadow detection from Gaofen-1 images
The reconstruction of the information contaminated by cloud and cloud shadow is an important step in pre-processing of high-resolution satellite images. The cloud and cloud shadow automatic segmentation could be the first step in the process of reconstructing the information contaminated by cloud and cloud shadow. This stage is a remarkable challenge due to the relatively inefficient performanc...
متن کاملRecognition of Multiple PQ Issues using Modified EMD and Neural Network Classifier
This paper presents a new framework based on modified EMD method for detection of single and multiple PQ issues. In modified EMD, DWT precedes traditional EMD process. This scheme makes EMD better by eliminating the mode mixing problem. This is a two step algorithm; in the first step, input PQ signal is decomposed in low and high frequency components using DWT. In the second stage, the low freq...

Reducing the number of colors in an image while preserving its quality, is of importance in many applications such as image analysis and compression. It also decreases memory and transmission bandwidth requirements. Moreover, classification of image colors is applicable in image segmentation and object detection and separation, as well as producing pseudo-color images. In this paper, the Kohene...
متن کاملA DWT and SVM based method for rolling element bearing fault diagnosis and its comparison with Artificial Neural Networks
A classification technique using Support Vector Machine (SVM) classifier for detection of rolling element bearing fault is presented here. The SVM was fed from features that were extracted from of vibration signals obtained from experimental setup consisting of rotating driveline that was mounted on rolling element bearings which were run in normal and with artificially faults induced conditio...
