Firstly , chromatism analysis and wavelet transform are used for color image compression coding . in this method , one of the three color components of a color image ( for example the g component of a rgb color image ) is coded using wavelet transform , and the chromatism between g and other two color components rg = r - g , bg = b - g is coded respectively using chromatism analysis . during decoding , g ~ is first reconstructed using wavelet inverse transform and inverse quantisation , and rg , bg are reconstructed using chromatism analysis inverse transform ; then r , b are calculated by r = g + rg and b = g + bg respectively 其一是應用色差分析和小波變換對彩色圖象進行壓縮編碼，該方法是對彩色圖象的三個色彩分量之一，如rgb圖象的g進行小波變換編碼，而對g與另兩個色彩分量的差值(即rg = r - g和bg = b - g )進行色差分析編碼，解碼則是通過反量化和小波逆變換得到g ^ ，通過色差分析的逆變換得到兩個重構的色差rg ^和bg ^ ，再算出r ^ = g ^ + rg ^ 、 b ^ = g ^ + bg ^ ，最后由r ^ 、 g ^ 、 b ^重構圖象。
This paper refers to several creation in compatibility with large volume of fed display and conversion of different video signal . it firstly used special central chip al300 , designed correlative circuits , successfully developed vga full - color fed console system , compatible with resolution 1280 1024 , achieved functions such as multi - video signal conversion and interleaving , met vga ’ s resolution of fed . it firstly designed and fabricated vga interface and separated video interface - - s - video , converting several video signals to 24 bits full - colored digital image signal in fed driving system , achieved separation of luminance signal and chromatism signal , enhanced the bandwidth of luminance signal 首次采用平板顯示專用控制芯片al300 ,設計并制作了相關配套電路,支持的最高分辨率是1280 1024 ,實現解隔行和多種視頻格式轉換的功能,滿足了fed顯示屏對vga分辨率的要求。首次在基于fpga的vga級彩色fed控制系統中設計并制作了vga接口和分離電視信號s - video接口,可以將多種視頻信號變換為fed驅動系統可用的24位彩色數字圖像信號,實現亮度信號和色差信號的分離,提高了亮度信號的帶寬。
Due to the image exists the instances of spin and distortion , in order adopting part small template proceed matching in order to reduce thereof impacts by as possible , besides small template matching may decrease calculation quantity , and it is propitious to real time of matching . looking into be on the impact of illumination , chromatism , under cloak circumstance template size and quantity select versus matching rate . matching primitive chooses gray , gray information measure large and most easy to obtain , but it is rather effected by illumination condition and chromatism , maximum matching rate restricted to 70 % 瓷磚缺陷檢測采用待測圖像與標準圖像作差法,作差法對匹配精度要求較高,因此在匹配誤差存在的點進一步做了亞像素級的匹配;導彈目標識別,采用背景匹配的方法,統計背景移動距離指導目標的識別;叢林中移動目標識別,采用作差法找到目標區和背景區,分別采用不同的模板和閾值匹配,統計目標區匹配結果。
Specially , the axial tensile strength of the interface of the new and old concrete has reached above 2 . 40mpa , greatly surpassing the preconcert goal ( > 1 . 0mpa ) , and its flexural strength also above 5 . 80mpa , having surpassed the preconcert target and the standard request ( 4 . 50mpa ) . ( 2 ) after hardening 4h and 8h the compressive strength of the patched concrete is bigger than 20 mpa , which can satisfy the request of fast patching . ( 3 ) the ych color material , which is mixed into rapid sulfoaluminate cement - concrete patching material , can take better effect and avoid chromatism on the appearance of new - old concrete 特別是新老混凝土界面的軸向抗拉強度已達2 . 40mpa以上,大大超過原定目標(大于1 . 0mpa ) ,其界面抗折強度也在5 . 80mpa以上,也已超過原定指標及規范要求(大于或等于4 . 50mpa ) ; ( 2 )修補混凝土硬化后4h 、 8h抗壓強度大于20mpa ,能滿足快速修補的要求; ( 3 )在快硬硫鋁酸鹽水泥混凝土修補材料中摻入自配的ych調色材料,能較好地起到調色作用,避免新老混凝土表面色差。
