You also need to take into account the problem of one step in the traversal process. This template slides 10 pixels at a time, so a total of 9 slides are required. In addition to the first No. 0 time, the total in the horizontal and vertical direction respectively have 10 such templates, a total of 100 templates. To calculate these 100 templates, the Haar feature on the whole picture can be calculated. And if our step size is set to

(func)即可。Two: Partial function (one of functools the functions in the module)1在介绍函数参数的时候,通过设定参数的默认值,可以降低函数调用的难度。而偏函数也可以做到这一点。2 int() Functions can convert a string to an integer, and when passed in only the string, the int() function defaults to decimal conversion:int(‘12345‘)12345But int() the function also provides additional base parameters, the default value is 10 . If you pass in base a parameter, you can do an n-binary conversion: >>> int ( ' 12345 ', base=
