Terahertz imaging technology plays an important role in the applications of high-resolution imaging and detection of small targets. The imaging system design is optimized with step-frequency signal in 220GHz frequency band as well as the imaging algorithms are conducted. In order to get high resolution, the 220GHz system is designed and realized with stepped frequency. the technology of high-resolution...
We propose a method for local stereo matching that reduces the number of matching comparisons, which also reduces the running time. By using hierarchical structure with suitable disparity candidate set, the proposed method maintains accuracy of local matching methods. Theoretical analysis and experimental results show that the number of comparisons of the proposed method is independent of the disparity...
Time-frequency imaging methods include many base functions, it is hoped that the best can be applied in two dimensional imaging. A experimental radar system is designed. STFT, WVD Harr and morlet wavelet transforms are simulated and compared, which shows WVD has the best quality of the ISAR images.
