Abstract: A plurality of groups of portrait components and a region in which the plurality of groups of portrait components are located are recognized from a first image, each group of portrait components corresponding to one human body, and a target region that includes a human face is determined in the region in which the plurality of groups of portrait components are located, to blur regions other than the target region in the first target image. A target group of portrait components including the human face is recognized from the first image, so that the target region in which the target group of portrait components is located is determined as a foreground region, and limbs of other people without a human face are determined as a background region. The disclosed system and method improve the accuracy of recognizing a foreground person and reducing incorrect detection in portrait recognition.

Abstract: A browser based application program extension method and device are provided. In response to a request to activate an application program, a page file and a browser core may be loaded. A script object may be embedded into the browser core to interact with other serving assemblies in an operation environment of the application program. The browser core may parse the page file and generate and display a corresponding application interface. The script object may receive a request from the application interface and invoke a serving assembly according to the request. The script object may return an invoked result to the application interface. Thus, the application program may be developed by combining web technology with the browser core. This may shorten application program development period and reduce development difficulty. Further, the application program may be used in any operating system without extra development effort.
