The next generation of warships might be virtually invisible to the human eye. This can be achieved by painting ships with metamaterial. These materials can bend light around object, making it to appear to an observer as though the waves have passed through empty space. We have developed a method to identify these ships target with the help of image processing. Research on the extraction of ship target...
This paper provides a comparative study of various spatial domain filters for speckle suppression in ultrasound images. Spatial domain filters are easy to implement on real time systems because they work faster than other methods like multi-resolution or wavelets based filters. Different filters have been evaluated experimentally on synthetic and real ultrasound images. Their performance is noted...
A method for designing a quadruple band bandpass filters using frequency transformations has been introduced. We have synthesized a 16-pole quadruple band bandpass filter using the frequency transformations for the validation of the proposed method.
A non-uniform bandwidth (NUB) spatio-temporal (ST) cone filter bank design is proposed for selectively filtering broadband three-dimensional (3D) plane waves (PWs). In the proposed structure, the tree-structured Octave filter bank in the temporal direction is employed in the analysis and synthesis part of the 3D cone filter bank. The temporal implementation of such tree-structured filter bank defines...
The probability hypothesis density (PHD) filter is a practical alternative to the optimal Bayesian multi-target Alter based on finite set statistics. It propagates the PHD function, a first-order moment of the full multi-target posterior density. The peaks of the PHD function give estimates of target states. However, the PHD filter keeps no record of target identities and hence does not produce track-valued...
