how to find hamming distance

Carefully read the code of the Orb, found that there are a lot of details are not very clear, in which the use of violence to test the distance of keypoints, with the Hamminglut, the Internet to find out only know, Hamming distance is the difference

The Hamming distance between and integers is the number of positions at which, the corresponding bits is different.Given integers x y and, calculate the Hamming distance.Note:0≤ x , y Example:input:x = 1, y = 4output:2explanation:1 (0 0 0 1) 4 (0

Similarity measurement between different samples is often needed for classification. The common method is to calculate the distance between samples ). The method used to calculate distance is very particular, and even related to the correctness of

We collected a large amount of text data through the acquisition system, but there are many duplicate data in the text that affect our analysis of the results. Before the analysis we need to remove these data duplication, how to select and design

When classifying, it is often necessary to estimate the similarity metric between different samples (similarity measurement), which is usually done by calculating the "distance" (Distance) between samples. The method used to calculate the distance

Hamming distance, as a method of measuring feature distance, has been applied in many occasions, and its main idea is to find the difference between the two characteristics of the size, it can be said that the similarity. I used in the image

The Hamming distance between and integers is the number of positions at which, the corresponding bits is different.Given integers x y and, calculate the Hamming distance.PS: To find the Hamming distance.Idea: The number of x and y binary xor 1Public 

When calculating the similarity of a string or graph, the two commonly used algorithms, one is the editing distance, the other is the Hamming distance.Simply put:Editing distance is the ability to turn a string into another string with several
