what 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

D. Hamming distance is used in the data transmission error control code inside, Hamming distance is a concept, it represents two (the same length) word corresponds to the number of different digits,We use D (x, y) to denote the Hamming distance

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

Through the collection system, we collect a large amount of text data, but there are a lot of duplicate data in the text that affects our analysis of the results. Before analysis, we need to remove duplication of the Data. How can we select and

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
