The virtual line based video vehicle detection algorithm is used extensively in intelligent transportation system (ITS) because of its high real-time performance, but it only utilizes luminance values of pixels on only one virtual detection line to detect moving vehicles, as a result, its false reject rate (FRR) and false accept rate (FAR) are high. In order to solve this problem, a virtual line group...
The growth in mobile communication and Internet usage has lead to increase in demand for robust transmission of compressed video over error prone channels. The quality of decoded video in erroneous environment depends on efficient detection and concealment of errors. In this paper, improved error detection and concealment techniques using syntactic, semantic and statistical information in MPEG-4 are...
Robust video transmission over wireless channels is very critical due to channel impairments and to their effect on the compressed bitstream. Error detection is a clue point as, if errors are detected, their concealment may be performed. However, traditional error detection techniques aren't enough for detection. In this paper, an improved error detection and localization technique is proposed. The...
