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 特别是新老混凝土界面的轴向抗拉强度已达2 . 40mpa以上,大大超过原定目标(大于1 . 0mpa ) ,其界面抗折强度也在5 . 80mpa以上,也已超过原定指标及规范要求(大于或等于4 . 50mpa ) ; ( 2 )修补混凝土硬化后4h 、 8h抗压强度大于20mpa ,能满足快速修补的要求; ( 3 )在快硬硫铝酸盐水泥混凝土修补材料中掺入自配的ych调色材料,能较好地起到调色作用,避免新老混凝土表面色差。

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 % 瓷砖缺陷检测采用待测图像与标准图像作差法,作差法对匹配精度要求较高,因此在匹配误差存在的点进一步做了亚像素级的匹配;导弹目标识别,采用背景匹配的方法,统计背景移动距离指导目标的识别;丛林中移动目标识别,采用作差法找到目标区和背景区,分别采用不同的模板和阈值匹配,统计目标区匹配结果。

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 其一是应用色差分析和小波变换对彩色图象进行压缩编码，该方法是对彩色图象的三个色彩分量之一，如rgb图象的g进行小波变换编码，而对g与另两个色彩分量的差值(即rg = r - g和bg = b - g )进行色差分析编码，解码则是通过反量化和小波逆变换得到g ^ ，通过色差分析的逆变换得到两个重构的色差rg ^和bg ^ ，再算出r ^ = g ^ + rg ^ 、 b ^ = g ^ + bg ^ ，最后由r ^ 、 g ^ 、 b ^重构图象。
