Image retargeting attempts to adapt images to different devices while preserving the salient contents. Most existing methods address retargeting of a single image. In this paper, we propose a novel image retargeting method for resizing a pair of stereo images. Naively retargeting each image independently will distort the geometric structure and will impair the perception of the 3-D structure of the...
A compact folded interdigital bandpass filter using low temperature co-fired ceramic (LTCC) technology is proposed. Strong capacitive couplings between the double-layer coupled stripline resonator structure are introduced to realize miniature bandpass filters. A design of an eight-pole Chebyshev folded filter with such structure is performed in this paper. The simulation response exhibits an insertion...
In this paper, a new kind of dual-mode Folded Substrate Integrated Waveguide (FSIW) filters in K-band with Low-Temperature Co-fired Ceramics (LTCC) technology is proposed. Dual-mode FSIW filter of single resonant cavity is designed to degenerate two modes: folded TE201 and TE102, which results in two transmission zeros on each side of the pass-band. To further validate its characteristics, a dual-mode...
A three order cross-coupling FSIW (Folded Substrate Integrated Waveguide) cavity filter with three TZs (Transmission Zeroes) is proposed firstly. By the merit of the LTCC (Low-Temperature Co-fired Ceramic) technology, the substrate area occupied by the filter is reduced by approximately 50% compared with the traditional SIW filter, and it still exhibits a sharp frequency selection performance. To...
Two compact microwave band pass filters used in Ka band LTCC frequency synthesizer are presented in this paper. The filters are buried in the Ferro-A6 substrate. Modified SIR structure is employed to improve the stop band rejection and minimize the size of the LTCC BPF. The design processes are proposed. The measured results of the BPFs agree well with the simulation.
In this paper, the control strategy of transformer coupling three phase bridge type solid state fault current limiter (TC-SSFCL) is presented. It is validated in an experimental system. It's proved that the control strategy ensures TC-SSFCL has excellent control performance and current-limiting effectiveness in its normal startup, operation and current-limiting conditions. Issues faced by TC-SSFCL...
In order to improve standardization, control level of railway track inspection, and monitor inspectors scientifically and accurately, this paper brings forward a supervisor mode of patrol inspection based radio frequency identification (RFID) and information management technologies. The railway track inspection system is composed of information buttons mounted in milestones or electric poles, portable...
In this paper, a design of narrowband cavity LTCC bandpass filter was presented, including basic synthesis, structure configuration and EM-simulation. According to full-wave EM simulation, insertion loss was less than 0.9 dB in the passband (34.5 GHz - 35.5 GHz) . At last, topology of the embedded LTCC BPF was in harmony with the whole LTCC transceiver module and can be realized very easily by LTCC...
This paper deals with an embedded multilayer LTCC interdigital bandpass filter. This compact filter is used in LTCC transceiver module to suppress the unnecessary frequency components in LO branch. According to validation, measured results are in good agreement with simulated results. The passband insertion loss and stopband suppression at concerned frequency points accomplishes suppression desires...
A compact high-selective stripeline SIR bandpass filter based on LTCC technology has been proposed in this study. Through the cross-coupling, the filter could provide a single pair of transmission zeros (TZs) near the passband, which greatly enhance the side-band rejection. Due to the optimization of impedance rate of the SIR, we could not only reduce the filter size, but also control the spurious-mode...
