Abstract: Detecting fine-grained similarity in image includes determining a core area of a search image by generating an image salient map from a plurality of layers of the search image and determining a connected area based on the image salient map. Feature descriptors are generated from the core area of the search image. A plurality of capsule vectors are generated from different ones of a plurality of keypoints of the feature descriptors. Capsule vectors of the search image are compared with capsule vectors of each image of the dataset to generate a top-K matrix. Similarity scores for the top-K matrix are calculated. One or more image of the dataset having fine-grained similarity with the search image are selected based a bundled similarity score for each image of the dataset. The bundled similarity score is a summation of the similarity scores of the image.

Abstract: Techniques manage application systems in an application environment. The application environment includes a first application system, a second application system and a third application system. First snapshot information of a first group of snapshots of the first application system is obtained, the first application system being in active state. Second snapshot information of a second group of snapshots of the second application system is obtained, the second application system being in standby state. It is determined whether the second application system and the third application system have a common snapshot based on the first snapshot information and the second snapshot information. Data is synchronized to the third application system depending on whether the second application system and the third application system have a common snapshot. Overheads required during data synchronization may be reduced as far as possible, and the efficiency of data synchronization may be improved.

Abstract: A method, computer program product, and computer system for creating, by a computing device, a first directory entry with a name using a majority protocol, wherein the creation may be done on a source side for a multi-protocol delta copy migration session. Minority protocol name information associated with the first directory entry using the majority protocol may be relayed to a destination side for the multi-protocol delta copy migration session, wherein the minority protocol name information is cached on the destination side. A second directory entry with the name using the majority protocol for the multi-protocol delta copy migration session may be created on the destination side. The name of the second directory entry created using the majority protocol may be reset to the minority protocol name created using the minority protocol name information cached on the destination side.

Abstract: Techniques perform data backup. Such techniques involve: in response to a first storage node to be switched to a second storage node, determining whether there is an ongoing data backup operation between the first storage node and a third storage node; and in response to the ongoing data backup operation between the first and third storage nodes, ceasing the data backup operation. The second storage node is used for backing up data of the first storage node in real time and the third storage node is used for backing up the data of the first storage node periodically. Accordingly, colliding operations can be prevented, system resource can be saved and processing efficiency can be improved.
