Traffic management always is a matter requiring the attention of highway system managers in terms vehicle monitoring and speed estimation. This paper proposes an efficient deep learning-based estimation on lanes Vietnam transport system. The input videos are recorded by fixed surveillance cameras. An optimized single shot multibox detector network, called SSD, utilized for license plate detecti...

The paper presents a methods to retrieve the speed of the sea surface from Along Track Interferometry (ATI) data beside the typical use for target speed retrieval, which is also mentioned. The describe technique provides for a data prefiltering in order to obtain the necessary accuracy because of the law speed range of the currents. Furthermore, an example of target velocity estimation is provi...

This letter deals with rotor position and speed estimation of permanent magnet ac drives. Two reduced-order observers, a linear (AO) and a nonlinear one (NLO), are compared. An adaptive speed estimation scheme is also considered. Analysis and simulations show that the NLO has better performance and demands less computational load than the AO plus the adaptive scheme.

Recently, speed sensorless control of induction motor drives received great attention to avoid the different problems associated with direct speed sensors. However, low speed operation with robustness against parameter variations remains an area of research for sensorless systems. Stator resistance is of greatest importance for good operation of speed sensorless systems in low speed region. In ...

A new technique is described for estimating the speed of a mobile station in a wireless system. The mobile speed maps the characteristic spatial scale of the received signal into a characteristic temporal scale. The continuous wavelet transform tracks changes in the temporal scale to estimate the mobile speed as a function of time. This technique requires neither knowledge of the average receiv...

Media processing applications are dominant in many new workloads today. These applications including 3D graphics, image compression, and signal processing, require tens to hundreds of billions of computations per second. To achieve real-time requirements, current media processors use special purpose architectures. Because of the changes in media applications and standards, flexibility is an imp...

In this paper, detailed studies have been performed for developing a real time system to be used for surveillance of the traffic flow by using monocular video cameras to find speeds of the vehicles for secure travelling are presented. We assume that the studied road segment is planar and straight, the camera is tilted downward a bridge and the length of one line segment in the image is known. I...
