| 1 | A NOVEL ALGORITHM OF MULTI-SENSOR IMAGE FUSION BASED ON WAVELET PACKET TRANSFORM显示文摘In order to enhance the image information from multi-sensor and to improve the abilities of the information analysis and the feature extraction, this letter proposed a new fusion approach in pixel level by means of the Wavelet Packet Transform (WPT). The WPT is able to decompose an image into low frequency band and high frequency band in higher scale. It offers a more precise method for image analysis than Wavelet Transform (WT). Firstly, the proposed approach employs HIS (Hue, Intensity, Saturation) transform to obtain the intensity component of CBERS (China-Brazil Earth Resource Satellite) multi-spectral image. Then WPT transform is employed to decompose the intensity component and SPOT (Systeme Pour I'Observation de la Therre ) image into low frequency band and high frequency band in three levels. Next, two high frequency coefficients and low frequency coefficients of the images are combined by linear weighting strategies. Finally, the fused image is obtained with inverse WPT and inverse HIS. The results show the new approach can fuse details of input image successfully, and thereby can obtain a more satisfactory result than that of HM (Histogram Matched)-based fusion algorithm and WT-based fusion approach. | Cheng Yinglei Zhao Rongchun Hu Fuyuan Li Ying | 2006 | Journal of Electronics(China)2006，23，2： | 3 |

| 4 | Effects of Different Flue-curing Technologies on Submicroscopic Structure of Flue-cured Tobacco Leaves显示文摘[Objective]This study aimed to compare the effects of low-temperature low-humidity tobacco flue-curing technology,moderate-temperature moderatehumidity tobacco flue-curing technology and moderate-temperature high-humidity tobacco flue-curing technology on submicroscopic structure of flue-cured tobacco leaves to provide theoretical basis for tobacco flue-curing. [Method] Middle leaves of tobacco cultivar K326 were collected in Pengshui County of Chongqing City for flue-curing experiment using three flue-curing technologies. Leaf samples were collected regularly in the flue-curing process,to investigate the submicroscopic structure of flue-cured tobacco leaves. [Result]Morphology changes and structural rupture of chloroplasts occurred at different time during three flue-curing processes. In low-temperature low-humidity flue-curing process,morphology changes and structural rupture of chloroplasts occurred late but rapidly; in moderate-temperature moderate-humidity flue-curing process and moderate-temperature high-humidity flue-curing process,morphology changes and structural rupture of chloroplasts occurred early but slowly. Among these three flue-curing processes,the speed of changes in mitochondria morphology,cristae number and membrane rupture presented an upward order of low-temperature low-humidity flue-curing process < moderate-temperature high-humidity flue-curing process < moderate-temperature moderate-humidity flue-curing process. In low-temperature low-humidity flue-curing process,starch granules in chloroplasts ruptured after flue-curing for 36- 48 h;in moderate-temperature moderate-humidity flue-curing process,starch granules in chloroplasts ruptured after flue-curing for 24- 36 h; in moderate-temperature high-humidity flue-curing process,starch granules in chloroplasts ruptured after flue-curing for 12- 24 h. [Conclusion]Using low-temperature low-humidity fluecuring technology could prolong the maintenance duration of the submicroscopic structure integrity of flue-cured tobacco leaves,which was conducive to fully decomposing and transforming substances in tobacco leaves and obtaining high-quality flue-cured tobacco leaves. | Guomin CUI Bojun WANG Rongchun LI Anding XU Yiyin CHEN Chao YANG Min PU | 2014 | Agricultural Biotechnology2014，3，1： | 1 |
| 5 | Effects of Different Flue-curing Technologies on Microscopic Structure of Flue-cured Tobacco Leaves显示文摘[Objective]This study aimed to compare the effects of Chinese quality-improving fragrance-increasing tobacco flue-curing technology,Chinese threestage tobacco flue-curing technology and Zimbabwean tobacco flue-curing technology on microscopic structure of flue-cured tobacco leaves to provide theoretical basis for tobacco flue-curing. [Method]Middle leaves of tobacco cultivar K326 were collected in Pengshui County of Chongqing City for flue-curing experiment using three flue-curing technologies. Leaf samples were collected regularly in the flue-curing process,to investigate the microscopic structure of flue-cured tobacco leaves.[Result]During three flue-curing processes,leaves,palisade tissues and sponge tissues shrank gradually. Three flue-curing processes exhibited significant differences in the peak of tissue shrinkage: microscopic structure of flue-cured tobacco leaves in Chinese three-stage tobacco flue-curing process shrank earliest,follower by Chinese quality-improving fragrance-increasing tobacco flue-curing process; flue-cured tobacco leaves in Zimbabwean tobacco flue-curing process presented the latest shrinkage. At 84 h post-curing,leaf thickness in three flue-curing processes showed a descend order of Chinese three-stage tobacco flue-curing process >Chinese quality-improving fragrance-increasing tobacco flue-curing process > Zimbabwean tobacco flue-curing process. Upper and lower epidermal cells in Zimbabwean tobacco flue-curing process ruptured earlier than other two flue-curing processes; eventually,the majority of cells ruptured and mixed with palisade tissues and sponge tissues. In Chinese quality-improving fragrance-increasing tobacco flue-curing process,only a small number of epidermal cells in dried leaves ruptured.Among three flue-curing technologies,Zimbabwean tobacco flue-curing technology exhibited the greatest damage to epidermal cells,followed by Chinese three-stage tobacco flue-curing technology; Chinese quality-improving fragrance-increasing tobacco flue-curing technology had the minimum damage to epidermal cells. Mesophyll cross-section exhibited significant morphological changes in stomata. To be specific,at 0- 12 h post-curing,stomata of tobacco leaves closed with slightly prominent stomatal apparatuses on upper and lower epidermis; at 24- 72 h post-curing,stomata of tobacco leaves changed gradually from opening to closure with significantly prominent stomatal apparatuses on upper and lower epidermis; at 84 h post-curing,stomata of tobacco leaves closed,and the majority of stomatal apparatuses were significantly prominent. In Chinese quality-improving fragrance-increasing tobacco flue-curing process,only a small number of epidermal cells ruptured at 84 h post-flue-curing; palisade tissues and sponge tissues shrank almost simultaneously. Significant gaps were observed between palisade tissues and between palisade tissues and sponge tissues. Chinese quality-improving fragrance-increasing tobacco flue-curing technology exhibited lower disorder level compared with other two flue-curing technologies. [Conclusion]Chinese quality-improving fragrance-increasing tobacco flue-curing technology was conducive to maintaining the microscopic structure integrity of flue-cured tobacco leaves and obtaining high-quality flue-cured tobacco leaves. | Guomin CUI Bojun WANG Rongchun LI Anding XU Yiyin CHEN Chao YANG Min PU | 2014 | Agricultural Biotechnology2014，3，2： | 1 |
| 6 | Fast Nonlocal Diffusion by Stacking Local Filters for Image Denoising显示文摘Many image denoising methods achieve state-of-the-art performance with little consideration of computation efficiency. With the popularity of high-definition imaging devices, these denoising methods do not scale well to the high-definition images. Therefore, a fast image denoising method is proposed to meet the demand of processing highdefinition images. Based on the analysis of the distribution of the distance distrs between the similar patches and their reference patches from a semantic aspect, the large distrss was found to occur while their contribution to the overall distribution was small. Therefore, the nonlocal filters was replaced in trainable non-local reaction diffusion (TNLRD) with local filters. For image with 4096 × 4096 resolution, the proposed method runs about 6 times faster than TNLRD via a single-thread CPU implementation. And the GPU implementation of the proposed method is about 10 times faster than the CPU implementation. Furthermore, the proposed model achieves competing denoising performance compared with TNLRD in terms of PSNR and SSIM. | Peng Qiao Weichu Sun Yong Dou Rongchun Li | 2019 | 国际计算机前沿大会会议论文集2019，，2： | 0 |
