This document describes a method for detecting vehicles in dense urban areas using aerial images. The method uses Histogram of Oriented Gradients (HoG) features and disparity maps from at least two subsequent images along with exterior orientation data, a digital elevation model, and a road database. Road segments from the database are projected onto the images using height data. Disparity maps are used to exclude elevated objects like buildings and vegetation. Region growing excludes homogeneous areas, and remaining areas are classified using HoG features. The approach was tested on images of Munich, achieving up to 70% accuracy in vehicle detection.

Cloudsim quality-differentiated video multicast in multirate wireless networks
This document describes a quality-differentiated video multicast scheme for multirate wireless networks called QDM. QDM aims to provide heterogeneous clients with differentiated video qualities matching their channel conditions. It first proposes a rate scheduling model to select the optimal transmission bitrate for each video frame to maximize total visual quality subject to minimum quality guarantees. It then presents QDM, a practical protocol that constructs a cluster-based structure to characterize heterogeneity and adapts transmission rates based on video quality perceived by cluster heads. Simulation results show QDM can efficiently adapt to network dynamics and variable bitrates, producing a 2-5 dB gain in average video quality over leader-based approaches.

It first proposes a rate scheduling model to select the optimal transmission bitrate for each video frame to maximize total visual quality subject to minimum quality guarantees. It then presents QDM, a practical protocol that constructs a cluster-based structure to characterize heterogeneity and adapts transmission rates based on video quality perceived by cluster heads. Simulation results show QDM can efficiently adapt to network dynamics and variable bitrates, producing a 2-5 dB gain in average video quality over leader-based approaches.

FLEXIBLE FEC AND FAIR SELECTION OF SCALABLE UNITS FOR HIGH QUALITY VOD STREAM...
Providing high quality video on demand (VoD) streaming service over wireless networks is very
challenging due to the limited capacity and error-proneness of the wireless environment. We propose a
flexible forward error correction (FEC) and a fair selection scheme of scalable units that utilize a layered
coding structure of H.264/SVC (scalable video coding). Three error-resilient techniques (e.g., unequal
error protection, FEC, and retransmission) are adapted to minimize the total distortion of VoD streaming
service. For flexible FEC, a rateless FEC code is adopted. The FEC code rates are based on the possible
number of retransmission, the condition of the wireless channel and the layered coding structure of
H.264/SVC for each packet. A theoretical study is performed to show how to utilize the possible number of
retransmission for an adaptive FEC code rate. With fair selection, regular and retransmission-requested
packets compete for resources without fixing the retry limit. Thus, excessive retransmission is prevented and
the proposed scheme effectively provides capacity-limited and delay-constrained VoD streaming services.
For this fair selection of scalable units, we formulate the problem using binary integer programming and
propose an effective low complexity selection algorithm based on a priority index. The proposed algorithm
prioritizes packets according to the priority index and the H.264/SVC structure. We show that the proposed
scheme can minimize the total video distortion compared to other heuristic procedures. Other effects of the
various factors are also considered for the performance of the new scheme

FEC-Forward Error Correction for Optics Professionals..www.mapyourtech.com
Forward error correction (FEC) adds redundancy to transmitted data to allow the detection and correction of errors without retransmission. FEC works by encoding data at the transmitter and decoding it at the receiver. It allows reliable data transmission over noisy communication channels and improves performance metrics like bit error rate. Common FEC codes include Reed-Solomon codes, which offer good error correction ability and are widely used in optical communication systems to improve transmission distance and efficiency.

Forward error correction (FEC) adds redundancy to transmitted data to allow errors to be detected and corrected without retransmission. It works by encoding data at the transmitter and decoding it at the receiver. FEC provides increased transmission distance and reliability by improving the bit error rate. Reed-Solomon codes are commonly used for FEC as they can efficiently correct multiple errors within a code block. The amount of redundancy added depends on the code's error correction capability, with higher correction requiring more overhead bits.
Adaptive network coding for broadband wireless access networks
This document describes a study on adaptive network coding schemes for broadband wireless access networks. It analyzes random network coding (RNC) and systematic network coding (SNC) decoding probabilities and selects SNC for developing an adaptive scheme called Frame-by-frame Adaptive Systematic Network Coding (FASNC). FASNC dynamically uses either Modified Systematic Network Coding (M-SNC) or Mixed Generation Coding (MGC) depending on per-frame network constraints. An analytical model is developed to evaluate the mean decoding delay and mean goodput of the proposed FASNC scheme, with results matching computer simulations.

FEC schemes typically tune the FEC rate in accordance with feedback information provided by the receiver. However, the feedback and FEC rate calculation processes inevitably have a finite duration, and thus the FEC rate implemented at the sender may not accurately reflect the current state of the network. This paper proposes an Enhanced Random Early Detection Forward Error Correction (EREDFEC) mechanism to improve the quality of video transmissions over Wireless Local Area Networks (WLANs). In contrast to most FEC schemes, the FEC redundancy rate is calculated directly at the Access Point (AP). Moreover, the redundancy rate is tuned in accordance with both the wireless channel condition (as indicated by the number of packet retransmissions) and the network traffic load (as indicated by the AP queue length). The experimental results show that the proposed ERED-FEC mechanism achieves a significant improvement in the video quality compared to existing FEC schemes without introducing an excessive number of redundant packets into the network.
