This disclosure provides a method and a system for detecting and recognizing a target object in a real-time video. The method includes: determining whether a target object recognition result Rof a previous frame of image of a current frame of image is the same as a target object recognition result Rof a previous frame of image of the previous frame of image; performing target object position detection in the current frame of image by using a first-stage neural network to obtain a position range Cof a target object in the current frame of image when the two recognition results Rand Rare different; or determining a position range Cof a target object in the current frame of image according to a position range Cof the target object in the previous frame of image when the two recognition results Rand Rare the same; and performing target object recognition in the current frame of image according to the position range Cby using a second-stage neural network. Therefore, the operating frequency of the first-stage neural network used for position detection is reduced, the recognition speed is accelerated, and the usage of CPU and internal memory resources is reduced.

A method and device are described for implementing instant communication. Information indicating that a first user is logged into an instant communication interface is obtained. On-line users are displayed to the first user in response to the login of the first user. A first user selects an object to follow from the on-line users and, information about the selected object to follow is received in response to the first user selecting the object to follow from the on-line users. The first user may be set into a first instant communication room in which the selected object to follow resides, for performing instant communication. The device includes: an obtaining module, a displaying module and a processing module. In this manner communication between strangers is facilitated and the efficiency of making friends is enhanced.
