Abstract: A method, an apparatus and storage medium are provided for setting a smart device management account. In the method, the apparatus receives a rights acquisition request at least carrying a login account and first location information of a first smart device. The apparatus acquires a first device group according to the first location information. When determining that the first smart device has management rights on smart devices in the first device group, the apparatus sets the login account of the first smart device as a management account of the first device group. The apparatus sends an authorization message to the first smart device and the smart devices in the first device group.

Abstract: An image processing method includes acquiring a first image during a first exposure time, and a second image during a second exposure time, wherein the first exposure time is smaller than the second exposure time; acquiring the image region with the luminance greater than a first threshold in the second image as a first over-exposure region; acquiring the image region located at corresponding positions of the first over-exposure region and in the first image as a second over-exposure region; comparing the second over-exposure region and the first over-exposure region, for acquiring a first moving-object region; excluding the first moving-object region from the second over-exposure region, to generate a third over-exposure region; acquiring the image region located at corresponding positions of the third over-exposure region and in the second image as a fourth over-exposure region; and combining the third over-exposure region and the fourth over-exposure region.

Abstract: A process for preparing sucrose-6-ester is provided, which comprises electrolyzing an electrolyte solution containing sucrose, an acylating reagent and a halide catalyst. Also disclosed is a process for preparing sucralose, which involves the preparation and chlorination of sucrose-6-ester followed by deacylation of the molecule. The process of the invention can be more readily performed with a higher yield than those in the art.
