查询词典 S-curve

The traditional snake model only applies the features of the curve, which did not adequately apply the feature of the image. But in the algorithm, the corners of the detected object is detected based on the MIC operator; the initialized curve is set based on the corners; the object is fitted according on the snake model. The traditional snake model highly depended on the initialized position of the curve and can not get well fitted effort for the image which has the corners and concaves. The proposed algorithm preferably solve the drawbacks.

传统的snake算法只考虑曲线本身的特征，并没有充分的利用被拟合图像本身的特征，而此算法首先检测被拟和目标的角点，然后以这些角点为基准进行曲线初始化，最后根据snake算法进行目标拟和；较好地解决了传统snake模型对初始化位置敏感、对有角点和凹陷的图像收敛效果差的缺点。

Steps of the invention are that an agitator in a main reaction region is started while water enters to implement the nitrification process under the hypoxic condition. When a maximum value appears on a pH value curve and an inflection point appears on an ORP curve, the stirring is stopped. When the last stirring stage is stopped, oxygen is added in the mixture for the degradation of organic compounds and the nitrification of nitrogen compounds. When a minimum value appears on the pH value curve, the aeration is stopped. The steps are repeated till the water inletting stage is finished. And an aerobic aeration stage is taken as an ending stage of a reaction period.
