To seek the sub-matrix by the way, that is the ans1,This is obviously because we enumerate the du

of the Board-for Loop To implement the chessboard first we think about what the chessboard is, there are a lot of squares, and then the black and white squares, first we draw the squares, the code is as follows:Copy the Code code as follows: echo " "; for ($i =1; $i "; for ($j =1; $j 54im"; } echo " "; } echo " "; ?> See the above board,

In a checkerboard consisting of a 2^k * 2^k, there is a square that is different from the other, and how to cover the other squares of this particular square, using the following four kinds of L-shaped dominoes.Four L-type dominoes such as 1Figure 1Special squares in the chessboard 2Figure 2The basic principle of the implementation is to divide the chessboard of

In the field of machine vision, camera calibration is a very basic task. At present, our frequently used calibration tools are OPENCV and MATLAB. OpenCV's Checkerboard Corner extraction API requires us to specify the horizontal points of the checkerboard in order to extract the corner points. Its main process is to take the picture two value, morphological processing, to find a number of four-sided, to eac
