This article mainly introduces the PHP implementation of the MYSQLDB read and write separation operation class, combined with the instance form of PHP read and write to the database of the implementation skills, and give the package of the specific use of the class, the need for friends can refer to the next This paper describes the PHP implementation of MYSQLDB read-write separation Operation class. Share to everyone for your reference, as follows: /*** php mysqldb Read/write separation class

integers. As shown in: If the R is set to 1, and the eight pixels sampled are evenly distributed on the circle. Because the vertices marked in red are the pixels to be encoded, their coordinates are integers (x, y ). The coordinates of the green points must not be integers, so the pixel values of the points cannot be obtained from the image. Of course, a simple method can be replaced by the value of the nearest vertex, but a better method is bilinear interpolation. That is, a linear co

Mean valueMathematical definition: An average is a measure of the trend in a set of data , which is the sum of all the data in a set of data divided by the number of this set of data. It is an indicator that reflects trends in the data set. matlab function: Mean>>x=[1,2,3]>>mean (x) =2If x is a matrix, its mean value is a vector group. Mean (x,1) is the mean of the column vector, and me

Recently in the video splicing project, which used the image of the single-matrix transformation, in the final image remapping, because the target image coordinates are non-integers, so need to use the interpolation method, with bilinear interpolation, the following post is mainly to view the blog of the predecessor of the bilinear interpolation algorithm principle of a summary, Thank you for some of Daniel's blog posts here.Http://www.cnblogs.com/linkr
