Claim 4:
5. The method according to claim 2, wherein:
determining the locally strengthened range corresponding to each element according to the center point and the window size comprises:
using, by the device, the center point as an expectation of a Gaussian distribution, and using the window size as a variance of the Gaussian distribution, and
determining, by the device, a locally strengthened range according to the Gaussian distribution determined according to the expectation and the variance; and

calculating strong and weak connections between every two elements based on the locally strengthened range, to obtain the local strength matrix comprises:
sequentially arranging, by the device, the strong and weak connections between every two elements according to a sequence of the elements in the input sequence, to obtain the local strength matrix, the strong and weak connections between every two elements being obtained by using the following formula:, G
