Interpolation
利用低通滤波器对图像进行插值放大:按放大的倍数对原图像进行插零,插零后的图片与低通滤波函数进行卷积,原先插入的零的位置自动替换为适当的插值,如此图像就已经插值放大了,图像质量还不错。(Double the number of pixels of each row and column by adding a zero value pixel between each pixel of the image.Then operate with two kinds of low-pass filters to get the enlarged image.)

UpgradeReport
利用回转窑生产氧化铝的工艺中,提出了一种新的基于SVR(支持向量回归)的烧成带温度软测量方法。即首先对从回转窑采集到的烧结图像进行预处理,消除噪声的干扰;然后利用大津方法分割出物料区和火焰区,并提取这些区域的图像特征;其次利用基于SVR方法建立的烧成带温度模型计算温度值;参数计算.(The use of alumina rotary kiln production process, a new-based SVR (support vector regression) of the burning zone temperature soft measurement method. That is first collected from the rotary kiln sintering image pre-processing to eliminate noise interference Otsu method and then use the materials division of the district and flame zones, and extraction of image features in these regions SVR-based method followed by the establishment of the burning zone temperature model temperature parameters.)
