Abstract: An image processing method includes: performing a progressive removal processing of raindrops with different granularities on an image with raindrops, to obtain an image subjected to the removal processing of raindrops, wherein the progressive removal processing of raindrops with different granularities comprises at least: a first granularity processing and a second granularity processing; and performing fusion processing on the image subjected to the removal processing of raindrops and a to-be-processed image obtained according to the first granularity processing, to obtain a raindrop-removed target image.

Abstract: Techniques are described for identifying the use of software applications, such as to determine an identity of a user interacting with a Web site or other electronic information service based on information regarding an application copy used by the user. When a communication is received from a software application, the communication is analyzed to attempt to identify a particular software application copy that sent the communication. Various types of information about a client software application copy may be used in the analysis, including information about particular configuration settings for the client software application and for the client computing device on which the client software application is executing. After a matching software application copy is identified for a received communication, possible inappropriate activities related to the received communication may be identified in various ways, including based on previous communications received from the same software application copy.
