There are several good ones on the market today and one can be found in your price range if you sift through all the numbers and terms.

有几个好的，今天在市场上可以找到一个价格范围，如果你在你所有的号码和翻查。

In the matching stage, the angle of feature vectors is used as the similarity measure in the high dimensional space directly. This similarity measure is invariant to the linear transformation of feature vectors. Compared with SIFT and normalized correlation, the proposed method needs no primary features such as edges, corners, gradient or shapes which are very unstable in low contrast and low NSR images.

在匹配过程中，以向量之间夹角的大小作为相似度度量，直接利用图像的灰度信息在高维向量空间中考虑图像之间的相似度，克服了在低照度、低信噪比的图像中求边缘、角点、梯度和形状等特征的困难，不受向量模大小以及向量平移的影响，即相似度的计算是线性光照不变的。

The algorithm adopts classical bilinear interpolation algorithm in the area of image other than the edges;concurrently the stairway detection is further made according to the outcomes of Canny edge detection to sift out the horizontal and vertical edges which will not produce jaggies distortion;but in edge areas where severe jaggies distortion will occur when using classical algorithm,the stairway thinning-based interpolation algorithm is implemented.This interpolation algorithm keeps stairways from being enlarged when zooming out the image,hence the goal of reducing jaggies distortion is achieved.

该算法在图像的非边缘区域采用经典的双线性插值算法；同时根据Canny边缘检测的结果，进一步进行阶梯检测，滤除不会产生锯齿失真的竖直和水平边缘；而在使用经典算法会产生严重锯齿失真的边缘区域，运用基于阶梯细化的插值算法；该插值算法在放大图像的同时，抑制边缘中的阶梯被放大，从而达到减少锯齿失真的目的。

Now to make the cake, take a large mixing bowl and first sift the polenta, flour, baking powder and cinnamon.

现在开始制作蛋糕，用一个大搅拌碗把第一次筛选的玉米粥，面粉，发酵粉和肉桂混合。

It's quite easy. You sift the lid, and pour some water in it.

这很容易。你提起盖子，再在里面灌些水。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
