This is a fast prime number list generator using sieve algorithm. This function returns a list of prime numbers which are lower than a specified argument.

This script finds the complement of a set of indices from a specific arange(n) array. Suppose, for example, you are given a linear array with 10 elements and you want to extract the elements from this array that have indices other than [1, 3, 5].You can then use this recipe to first find the...

Photographic document images are often rotated, if only slightly. This code mediates an input of a series of four points--assumed to be the corners of a rectangular document--in any order, as mouse clicks.Then it determines the orientation of the points and calculates a "quality" value, as an...
