摘要：
Although synthetic aperture radar (SAR) sensors function well at all times and under all weather conditions, the images they produce are not intuitively straightforward. A novel idea based on data fusion is introduced to translate SAR data into optical image in this paper. The proposed SAR-optical image translation is implemented using an intensity–hue–saturation (IHS) and wavelet transform integrated fusion (IHSW), so as to preserve as much as spatial details from SAR data, and minimize the spectral distortion of translated output. COSMO-SkyMed and ENVISAT-ASAR images are translated into optical images with the fusion of Landsat TM images, and the fusion results are compared with some conventional fusion methods, as well as the texture synthesis approach. Quality assessment of different fused outputs is carried out by using six quality indices. Visual and statistical comparisons of the final results indicate that the proposed approach achieves an effective translation from SAR to optical image and is superior to texture synthesis-based algorithm in terms of preserving spatial and spectral information. The proposed translation technique presents an alternative to improve the interpretability of SAR images.

摘要：
The availability of very high spatial resolution (VHR) remote sensing imagery provides unique opportunities to exploit meaningful change information in detail with object-oriented image analysis. This study investigated land cover (LC) changes in Shahu Lake of Wuhan using multi-temporal VHR aerial images in the years 1978, 1981, 1989, 1995, 2003, and 2011. A multi-resolution segmentation algorithm and CART (classification and regression trees) classifier were employed to perform highly accurate LC classification of the individual images, while a post-classification comparison method was used to detect changes. The experiments demonstrated that significant changes in LC occurred along with the rapid urbanization during 1978–2011. The dominant changes that took place in the study area were lake and vegetation shrinking, replaced by high density buildings and roads. The total area of Shahu Lake decreased from ~7.64 km<sup>2</sup>to ~3.60 km<sup>2</sup>during the past 33 years, where 52.91% of its original area was lost. The presented results also indicated that urban expansion and inadequate legislative protection are the main factors in Shahu Lake's shrinking. The object-oriented change detection schema presented in this manuscript enables us to better understand the specific spatial changes of Shahu Lake, which can be used to make reasonable decisions for lake protection and urban development.<br/> 2018 by the authors.

摘要：
Urban lakes are important natural, scenic and pattern attractions of the city, and they are potential development resources as well. However, lots of urban lakes in China have been shrunk significantly or disappeared due to rapid urbanization. In this study, four Landsat images were used to perform a case study for lake change detection in downtown Wuhan, China, which were acquired on 1991, 2002, 2011 and 2017, respectively. Modified NDWI（MNDWI） was adopted to extract water bodies of urban areas from all these images, and OTSU was used to optimize the threshold selection. Furthermore, the variation of lake shrinkage was analysed in detail according to SVM classification and post-classification comparison, and the coverage of urban lakes in central area of Wuhan has decreased by 47.37 km2 between 1991 and 2017. The experimental results revealed that there were significant changes in the surface area of urban lakes over the 27 years, and it also indicated that rapid urbanization has a strong impact on the losses of urban water resources.

摘要：
Aiming at solving the problems of low efficiency and complicated operation of 3D modeling in the process of virtual product development of national culture, this paper discusses a synthesis approach of surface geometry model based on data-driven. Firstly, a shape-based matching algorithm is used to retrieve the corresponding components in the database. Secondly, a new model will be generated through segmenting and assembling these components. Finally, this approach is applied to construct 3D model of scenes and characters in ancient Badong town. The application shows that this approach can generate the geometric model of characters and scenes efficiently and economically in cultural activities.
