Provided is a system and method for estimating the motion of a target inside a tissue based on surface deformation of the soft tissue. The system consists of an acquisition unit, a reference input unit, two surface extraction units, a target position extraction unit, a feature calculation unit, and a target motion estimation unit. The method includes: the acquisition unit acquires an image Iof the soft tissue; the surface extraction unit extracts a surface fof the soft tissue from I; the reference input unit acquires a reference image Iof the soft tissue; the surface extraction unit and the target position extraction unit respectively extract a reference surface fof the soft tissue and a target reference position tfrom I, the feature calculation unit calculates deformation feature Ψof frelative to f, the target motion estimation unit estimates the target displacement based on Ψand t.

Behavior data associated with a user is obtained. The behavior data is generated when the user uses an Internet service and includes a user identification and identification information indicating the Internet service. At least one predefined carbon-saving quantity quantization algorithm is determined based on the identification information related to the Internet service. A carbon-saving quantity associated with the user is calculated based on the obtained behavior data and the determined at least one predefined carbon-saving quantity quantization algorithm. Based on the calculated carbon-saving quantity associated with the user and the user identification, user data is processed. The user data is related to the carbon-saving quantity associated with the user.
