Performance of content-based image retrieval technology used in clothing image retrieval cannot meet user's requirement due to the 'semantic gap' between low-level visual features and the richness of human semantics and it's time consuming to searching images in a growing number on the internet. In order to reduce the 'semantic gap' and improve the searching speed, this paper introduces a novel clothing image retrieval method based on color semantic classification. In this method, database images are classified into different categories with color semantic features and indexed by their visual features. In the retrieval process, images with the same semantic category are selected as candidates and further ranked by their visual features. The sematic information can also be used integrated with text information lab.led on the internet. Experimental results demonstrate our proposed method provides promising retrieval performance in less time than previous methods.

With only three program pins and without any off-chip devices, the chip has 36-program states by taking different connections for the 3-program pins. The chip can monitor the voltage from 1.5v to 5.0v with 0.1v step. Special SH circuit and current limited digital blocks are employed to achieve ultra low quiescent power. The implementation is based on 2M1P 0.5um mixed signal process, the die area is 0.24mm2, and the quiescent current is only 3uA.

Currently the ASIC applications such as multimedia processing require shorter time-to-market and higher performance. Furthermore, with the IC manufacturing technology developing continually, from transistor level to logic gate level, the size of standard cells in digital circuits is increasing correspondingly. New methodology should be proposed to meet the need for shorter time-to-market IC industry, and the requirement of advanced IC manufacturing technology. This paper proposed the concept and principle of operator design methodology, then focused on the entropy coding application by the reconfigurable operator and finally gave the synthesis data. The results show that compared with the hardware design at the same cost of resources, this methodology can obtain hardware of suitable performance with regular structure. What is more, it can improve the design speed efficiently. ©2010 IEEE.

This paper deals with the design of variable bandwidth linear-phase FIR digital filters by weighted least square method. This proposed algorithm is constructed by a linear combination of fixed-coefficient linear-phase filters, of which the variable bandwidth characteristics are provided by an embedded tuning parameter. Using the weighted least square objective function, the optimal solution is obtained by solving a set of linear equation, which is an error function reflecting the difference between the desired variable bandwidth filter and the practical filter. The proposed algorithm can implement the variable digital filter efficiently by the familiar Farrow structure with only one variable spectral parameter that determines the bandwidth. Mathematics deduction and simulations show this algorithm is simple and effective in designing FIR variable digital filter with better performance than previous ones. © 2010 IEEE.

This paper proposes a novel technique of dynamic context management scheme for coarse-grained reconfigurable array DSP architecture, which effectively reduces the power consumption and speedup reconfigurable process. The technique permits background loading of configuration data without interrupting the regular execution, overlapping computation with reconfiguration. And stored configurations can be switched dramatically reducing reconfiguration overhead if the next configuration is present in one of the alternate contexts. The proposed technique has been verified in ReMAP (Reconfigurable Multi-media Array Processors) with the Discrete Cosine Transform (DCT) of H.264 and its performance exceed other DSP and multimedia extension architectures by 1.2x to 6.2x. ReMAP was fabricated with SMIC's 0.18um CMOS process mainly for multi-media applications(1).

Verification of processors with high performance is becoming more and more time-consuming and even gradually turning into the bottleneck of the processor design. The Verification of Reconfiguralbe Multimedia Array Processor(ReMAP) we designed for multimedia processing and its internal component Reconfigurable DSP(ReDSP) is also no exception. A high-speed verification platform based on emulator is proposed for ReDSP and ReMAP. We demonstrate the hardware architecture of the platform and different verification modes it supports. A software verification model is proposed, and the evaluation results show a great acceleration rate compared to software simulation1. ©2009 IEEE.

5th International Conference on Wireless Communications, Networking and Mobile Computing, WiCOM 2009

Optimum partial transmit sequence method (OPTS), as one of the highest-performance PAPR reduction techniques, has very high computational complexity. Most sub-optimal schemes which are based on iterative PTS (IPTS), aim at balancing PAPR reduction performance and complexity by expanding the searching space of phase factor sequence with more iterative operations. A novel scheme is presented to further lower the complexity of PTS. This scheme samples every partial transmit sequence, obtains some peak-position samples with the largest magnitudes and then constructs PTS sampling sequence. A proper phase factor sequence can be got through processing PTS sampling sequences according to the principle of OPTS or sub-optimal PTS. Because PTS sampling sequences have fewer samples, the new method can achieve a low complexity. Besides, simulation results show that the new scheme has good PAPR reduction performance. ©2009 IEEE.

Currently the DSP applications such as multimedia processing raise the demands to IC designers for more flexibility, higher performance and shorter time-to-market. To solve these problems, this paper proposed a novel reconfigurable operator based IC design methodology for multimedia applications. Four kinds of reconfigurable operators and their logic meanings are introduced in this paper as well as the design flow. An archetypal reconfigurable circuit with 4*4 reconfigurable computing operator, reALU, is implemented in our research using SMIC 0.18 um CMOS, achieving the performance 2.4 GOPS at 150 Mhz at 1.62 v. Several algorithms such as SAD and DCT are mapped into the array processor, which show the better performance than the traditional digital signal processors.

OFDM is facing great opportunities and challenges in current broadband communication era. These opportunities and challenges derive from the native advantages and disadvantages of OFDM technology respectively. Too high PAPR is one of the main problems that prevent OFDM from being used more generally in broadband systems. Many approaches such as clipping and filtering, coding, SLM, PTS, and tone reservation have been studied to reduce the peak magnitude of OFDM symbols. In these approaches, tone reservation is considered as one of the most promising methods because of no additional distortion, no side information, and low implementation cost. In this paper, a novel tone reservation scheme is presented. Its essential idea is that a subcarrier selected from all reserved subcarriers for PAPR reduction should have a phase close to one of phi, pi/2+phi, pi+phi and -pi/2+phi, at the peak location in time domain, where phi is the phase of the peak sample. This results in no complex multiplication and division in the novel scheme. In addition, the floating positions of such selected subcarriers in frequency domain are helpful to the convergence of the algorithm. The simulation results show that the scheme can provide good performance and fast convergence.

In OFDM system, because of sensitivity to carrier frequency offset, frequency offset must be compensated before DFT in the receiver. In this paper, we present a maximum likelihood estimation for carrier frequency offset, based on OFDM symbol has no virtual sub-carriers. The estimation are compose of two parts, blind estimation makes use of cyclic prefix for every symbol and data-aid estimation makes use of two consequent OFDM symbols which are similar or relative to each other. Data-aid estimation performs well and simulation result converges upon Cramer-Rao lower bound. Blind estimation performs inferior, but it can be used in tracking mode.
