between 1~10, in theory 1-10 the probability that each number appears is 10%, But in fact I found that the probability of 1 and 10 appearing is about half the probability of other numbers appearing! So it's not fair to use Math.random () to generate random numbers of lottery programs. for (var i = 0; i ) { ~function() { var x = i+1, = 0, = 1000000; for (var j =
With the development of remote sensing technology, more and more methods are available to obtain image data. The application of RGB image data is particularly outstanding. After obtaining images, data preprocessing is the first thing to bear the brunt. This is tedious and mechanized, but it is still very important. For row slices or RGB data that have undergone initial processing, there is no spectral information, and only the corresponding R, G, and B band information is available, during data
