Multi-transmitter multi-receiver passive radar, which locates target in the surveillance area by the reflected signals of the available opportunistic transmitter from the target, is of interest in many applications. In this paper, we investigate different signal processing scenarios in multi-transmitter multi-receiver passive radar. These scenarios include decentralized processing of reference ...

Due to the absolute value involved, the first absolute central moment can be divided into two complementary filters: a positive deviation ep and a negative deviation en. Both ep and en can be used separately to highlight edges, lines, line endings, corners and junctions in images. Furthermore, the recovered edge information can be usefully combined to obtain additional information that would no...
Preliminary notes This paper describes a development of systems with limited capacity and limited performance requires a specific approach in the implementation phase especially if the application has high demands which exceed the possibilities of the used hardware. The paper specifies the compression methods used for video signal processing from the camera, which is scanned and detected in the...

Today’s smart phones, with their embedded highresolution video sensors, require computing capacities that are too high to easily meet stringent silicon area and power consumption requirements (some one and a half square millimeters and half a watt) especially when programmable components are used. To develop such capacities, integrators still rely on dedicated low resolution video processing co...
A digital video signal provides many advantages over analog signals: digital signals can be processed using computers or signal processors and transmitted via digital networks. Transmission via existing (phone) lines and non-wearing recording on hard disks are promoting the trend toward digital video signals. Because a digitized video signal has a very high data transfer rate of 216 Mbit/s (acc...
many of the video processing algorithms cannot be implemented in real time on general computers, due to their computational complexity. for an efficient implementation, a custom hardware that can be reconfigured for the algorithm, is used. in this paper a new acceleration hardware based on fpga elements is proposed. this hardware can be adapted with the processing algorithm through fpga design ...
