Abstract: In one example method, a first image including M objects is obtained. For N objects in the M objects, when N is greater than or equal to 2, arrangement orders of the N objects is determined, where an arrangement order of any one of the N objects is determined based on at least one of a scene intent weight, a confidence score, or an object relationship score. The scene intent weight is used to indicate a probability that the any object is searched in a scene corresponding to the first image, the confidence score is a similarity between the any object and an image in an image library, and the object relationship score is used to indicate importance of the any object in the first image. Search results of some or all of the N objects are fed back according to the arrangement orders of the N objects.

Abstract: Techniques for storage management involve determining, in response to a detection that a disk changes from an unavailable state to an available state, at least one candidate storage unit associated with the disk; acquiring historical access information about the at least one candidate storage unit, the historical information comprising information related to a write request directed to the at least one candidate storage unit when the disk is in the unavailable state; determining a target storage unit from the at least one candidate storage unit based on the historical access information; and rebuilding the target storage unit.

Abstract: Techniques for rebuilding a disk array involve, in response to receiving a message for rebuilding disk arrays in a storage system, determining a target disk that causes rebuilding. Such techniques further involve determining from the disk arrays a set of disk arrays related to the target disk, and generating subsets of disk arrays from the set of disk arrays, each subset including disk arrays that can be rebuilt in parallel. Such techniques further involve determining, based on a number of disks included in each subset, a target subset from the plurality of subsets, and rebuilding disk arrays in the target subset in parallel. Accordingly, a disk array that is most suitable for parallel rebuilding may be determined, and the process of rebuilding the disk array is sped up. Such techniques reduce the delay caused by performing rebuilding, and improve rebuilding efficiency.

In accordance with such a technique, a data access request which is from a host system and for a first storage unit in the first storage system is received, wherein the first storage unit is a secondary storage unit; and the data access request is forwarded to a second storage unit in a second storage system associated with the first storage unit via a redirection link from the first storage system to the second storage system, wherein the second storage unit is a primary storage unit. Through such techniques, the host system can be allowed to send a data access request for the secondary storage unit, so that the host system does not need to resend the data access request, thereby reducing delay and interruption caused by such requests.
