This paper presents a robust and reliable system that navigates the wheelchair robot without manual initialization or a priori information in real-time in outdoor environments. The system can extract various lane boundaries including straight and curved lanes under different conditions. It is robust against noise, shadows, and illumination variations in the captured road images. The straight la...

In this paper, we propose a new data-driven model to simulate the process of lane-changing in traffic simulation. Specifically, we first extract the features from surrounding vehicles that are relevant to the lane-changing of the subject vehicle. Then, we learn the lane-changing characteristics from the ground-truth vehicle trajectory data using randomized forest and back-propagation neural net...

In this paper, a Catmull±Rom spline-based lane model which describes the perspective e€ect of parallel lines has been proposed for generic lane boundary. Since Catmull±Rom spline can form arbitrary shapes by di€erent sets of control points, it can describe a wider range of lane structures compared with other lane models, i.e. straight and parabolic models. Moreover, the lane detection problem h...

Aiming at the lane change behavior recognition requirements for vehicle active safety system, natural driving test in real road were carried out and different parameters related to lane change behavior were collected synchronously. Firstly, parameters were processed with Kalman filter to increasing the potential relevance among sample data. Then, SVM model was established for lane change recogn...

As a tool for predicting stationary signals, the Least Mean Squares (LMS) algorithm is widely used improvement, the family of normalised LMS algorithms, is known to outperform this algorit However, they still remain sensitive to selecting wrong parameters, being the learning coefficientm the signal history length M. We propose an improved version of both algorithms using a Fast L Approach, base...

Figure 1. IFNGR1 RFLP detected by Southern blot analysis of Taql digested human DNA. The two alleles arc identified by 6. lkb (Al) and 3.2+2.9kb (A2) bands in a .8% agarosegel. Lane 1: Al homozygous; lane 2: A2 homozygous; lane 3: heterozygous. Hybridization and washing conditions were 50% formamide, 3x SSC, 37°C and .2x SSC, 60°C, respectively. figure l.VIL 2 RFLP detected by Southern Blot ana...

In this paper, we propose an integrated system that combines vehicle detection, lane detection, and vehicle distance estimation in a collaborative manner. Adaptive search windows for vehicles provide constraints on the width between lanes. By exploiting the constraints, the search space for lane detection can be efficiently reduced. We employ local patch constraints for lane detection to improv...
