Dynamic Regulation is widely used in optimization problems. Is an important method. The general steps are as follows: 1) describe the structure of the Optimal Solution 2) recursively define the value of the Optimal Solution 3) use the bottom-up

Compared sorting algorithms have at least O (nlgn) time complexity. For integer sequences, the time complexity of O (n) can be reached under certain conditions. There are mainly counting sorting and base sorting. The two algorithms are described

Ransac is short for "random sample consensus. This algorithm is an iterative method used to estimate mathematical model parameters from a group of observations. It is proposed by Fischler and bolles in 1981. It is a non-deterministic algorithm,

In image processing, it is often necessary to calculate the diameter and center of multiple objects. Therefore, border tracking is a very effective method. 1) getoneedge Algorithm for determining the boundary and region of an object The basic
