Prerequisites: a normal two-table connection is required to query the detailed information. Table A contains A large table with tens of thousands of test data records. Table B contains about 1000 million data records in A small table. 1. for the un-optimized SQL statements written in a rush (for the highlighted topic, the returned field is replaced by "*" without the previous outline: the requirement is to connect two common tables to query the detailed information. Table A contains A large tabl

the original image scale difference is very large, at this time again that the original picture convolution is a bit two), And the image needs to be reset size , so the calculation method is large. Surf algorithm to operate the integral image, convolution is only related to the previous image, the method of reducing the sample is to apply for the size of the image kernel , which is also the SIFT algorithm and surf algorithm in the use of pyramid principle is different. The surf algorithm agrees

You can set a color. The general syntax of notation is #aabbcc. And there are no spaces, commas, and other separator
