Object-based change detection has been the hotspot in remote sensing image processing.A new approach toward object-based change detection is *** two different temporal images are unitedly segmented using the mean shift procedure to obtain corresponding *** change detection is implemented based on the integration of corresponding objects’ intensity and texture *** are conducted on both panchromatic images and multispectral images and the results show that the integrated measure is robust with respect to illumination changes and *** color detection is conducted to determine whether the color of the unchanged objects changes or not when dealing with multispectral *** verification work is carried out to show the accuracy of the proposed approach.

CuO-CoO-MnO/SiO2nanocomposite aerogels and xerogels were prepared using tetraethyl orthosilicate（TEOS） as Si source,and aqueous solution of Cu,Co and Mn acetates as the precursor via sol-gel process,CO2supercritical drying（SCD） technique or ambient pressure drying *** microstructure of the CuO-CoO-MnO/SiO2nanocomposite aerogels and xerogels were characterized by field emission scanning electron microscopy（FE-SEM）,transmission electron microscopy（TEM） and X-ray diffraction（XRD）.The specific surface area,pore size and pore size distribution of the nanocomposite aerogels and xerogels were determined by the Brunauer-Emmett-Teller（BET） *** results showed that CuO-CoO-MnO/SiO2nanocomposite aerogels are porous,with a pore size distribution of 2-50 nm,an average pore size of 19.4 nm,a specific surface area of 3.4.9 m2/g and a particle size distribution of 10-150 nm,whereas the pore size distribution of CuO-CoO-MnO/SiO2composite xerogels is 1.7-128.6 nm,the average pore size is only 9.9 nm,the specific surface area is only 99.1 m2/g,and the particle size distribution is 100-500 *** structure of CuO-CoO-MnO/SiO2nanocomposite aerogels is favorable to increase the loading of catalysts.

＜正＞Digital halftoning is a technique used for binary devices such printers to simulate the continuous tone image. But the quality of halftone prints produced by printers can be limited by random dot-placement errors. In this paper, we propose a printer model and human visual model based method on tone-dependent error diffusion （TDED）. First we analyses the Printer Model and HVS （Human Visual System） used in halftoning algorithm. And based on the Floyd-Steinberg error diffusion algorithm, we train the tone-dependent weights matrix on the different tones using an error within a human visual system. In the experiment, we use HP LaserJet 1010 printer and simulated printer to test the result and compare the quality of the halftone image created by the new algorithm, and both them show very good halftoning quality.

＜正＞The digital imaging is becoming the main method of producing of the original manuscript of printing industry, digital original manuscript color gamut restriction print systematic color manage full play of efficiency not merely, still influence the quality of the printed matter directly. This text can propose a science quantitative analysis digital original manuscript method of color gamut accurate, and through relevant experiment compare various formation of image environment to digital original manuscript influence of the colour gamut, have obtained some achievements with value.
