Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It is to be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element of a same type from another. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Referring to fig. 1, fig. 1 is a flowchart of a picture retrieval method according to an embodiment of the present invention, and as shown in fig. 1, the picture retrieval method includes the following steps:
The picture to be retrieved is a picture which is selected by a user and needs to be searched. The picture to be retrieved can be a picture on a page or desktop of the retrieval system. And the user can select by uploading or dragging on a page or a desktop. The picture to be retrieved can be a picture obtained by means of USB flash disk copying, webpage downloading, cloud downloading, local storage and the like.
And 102, judging whether the retrieval times of the picture to be retrieved meet a preset retrieval time threshold value or not.
The preset retrieval frequency threshold is preset and is used for judging whether the picture to be retrieved is a condition threshold of frequently retrieving pictures. The preset retrieval time threshold may be set according to an actual requirement, for example, the preset retrieval time threshold may be set to 2 times, 3 times or more. The number of retrieval times is the number of times that the picture to be retrieved is retrieved in the retrieval system, for example, when the retrieval picture a is acquired, the retrieval picture a is retrieved before and 2 times, and then the number of retrieval times of the retrieval picture a is 2 times.
Specifically, referring to fig. 2, fig. 2 is a flowchart of a method provided in step 102 in the embodiment of fig. 1, and as shown in fig. 2, step 102 includes:
The retrieval records are records of the pictures to be retrieved in the retrieval system.
Specifically, after the picture to be retrieved is obtained, the retrieval record of the picture to be retrieved can be searched in the retrieval system, if the retrieval record of the picture to be retrieved is found in the retrieval system, it is indicated that the picture to be retrieved has the retrieval record, and if the retrieval record of the picture to be retrieved cannot be found in the retrieval system, it is indicated that the picture to be retrieved does not have the retrieval record.
Specifically, when the retrieval system retrieves a picture each time, the retrieval record of the picture is reserved within a certain preset time period, and if the picture is retrieved again within the preset time period, the retrieved retrieval times are accumulated on the basis of the first retrieval. Therefore, when the retrieval record of the picture to be retrieved is detected, the retrieval times of the picture to be retrieved can be acquired. For example, when a B picture is searched for the first time, the number of searches is recorded as 1, and when a B picture is searched for the second time, the number of searches for a B picture is recorded as 2, so that the number of searches for a B picture can be obtained as 2. By analogy, if the later-stage B picture is searched again, the searching times are correspondingly increased by 1 time. Of course, the preset time period can be set according to actual needs, and the preset time period can be set to be one hour, one day, one week, one month, and the like. The setting can be specifically carried out according to the effectiveness of picture retrieval.
As an implementation manner of the embodiment of the present invention, the user ID of each time the picture to be retrieved is obtained according to the retrieval record. And acquiring the current user ID of the current retrieval user. And counting the retrieval times of the current user ID retrieval of the picture to be retrieved according to the user ID retrieved each time of the picture to be retrieved.
The user ID is identity information corresponding to a user executing the retrieval task. Because in the retrieval system, a plurality of retrieval users can exist, each retrieval user has an account number, and each user has the authority and the standard for collecting frequently retrieved pictures. The current user ID may be account information of a user currently performing a search task.
More specifically, the number of retrieval users in the retrieval system may be multiple, and when the same picture to be retrieved is retrieved by different users, the total number of times of retrieving the picture to be retrieved is reached, but the picture is not retrieved frequently for all users. Therefore, it is necessary to know the user ID to be retrieved each time in the retrieval record of the picture to be retrieved, and then count the retrieval times of different users for the same picture to be retrieved. Of course, when a retrieval task is performed each time, only the retrieval times corresponding to the current user ID in all the retrieved retrieval records of the picture to be retrieved need to be counted. Therefore, when each user executes the retrieval task, the retrieval times of a certain picture to be retrieved can be judged according to the retrieval records of the user. Furthermore, the statistical quantity can be reduced, and the retrieval efficiency can be improved.
And step 203, comparing the retrieval times with a preset retrieval time threshold, and judging whether the retrieval times meet the preset retrieval time threshold according to the comparison result.
Specifically, after the number of retrieval times of the picture to be retrieved is determined, the number of retrieval times can be compared with a preset retrieval time threshold value. And if the retrieval times are greater than or equal to the preset retrieval times threshold, indicating that the retrieval times meet the preset retrieval times threshold. Otherwise, the searching times do not meet the preset searching times.
As an implementation manner of the embodiment of the present invention, the number of times of retrieval of the picture to be retrieved by the current user ID is compared with a preset retrieval number threshold of the current user ID, and whether the number of times of retrieval of the picture to be retrieved by the current user ID satisfies the preset retrieval number threshold of the user ID is determined according to the comparison result.
More specifically, in the retrieval system, each retrieval user can set a preset retrieval frequency threshold value, and because different retrieval users have different judgment standards for frequently retrieving pictures according to retrieval tasks of the retrieval users, each retrieval user can set a unique preset retrieval frequency. Therefore, the retrieval times of the picture to be retrieved corresponding to the current user ID can be compared with the preset retrieval time threshold corresponding to the current user ID, and whether the picture to be retrieved is the frequent retrieval picture corresponding to the current user ID is determined according to the comparison result.
And 103, if the retrieval times meet a preset retrieval time threshold, determining that the picture to be retrieved is a frequently retrieved picture, and storing the picture to be retrieved in a preset first storage space.
The frequently retrieved pictures are pictures that the user needs to retrieve frequently. The preset first storage space is arranged in the retrieval system. The user logs in the retrieval system to directly use the preset first storage space. The preset first storage space can be called as a temporary storage rack in the retrieval system and is used for storing frequently retrieved pictures for a long time. The preset first storage space can store a plurality of frequently retrieved pictures. Of course, the user may also clean the frequently retrieved pictures in the preset first storage space regularly according to actual needs.
Specifically, when the retrieval frequency of the picture to be retrieved is greater than or equal to the preset retrieval frequency, the picture to be retrieved can be a picture which is frequently retrieved by the user, and therefore, the picture to be retrieved can be stored in a preset first storage space, so that the picture to be retrieved can be conveniently stored for a long time, and the picture can be conveniently retrieved next time.
And step 104, retrieving by taking the frequently retrieved pictures as a first retrieval target to obtain a first retrieval result.
The first retrieval target is a target picture which needs to be retrieved by a user. The first search result is result data collected according to a first search target. The first search result may be picture data, text data, table data, voice data, archive data, or the like.
Specifically, when the user aims to search for pictures, the first search result is picture data corresponding to the frequent picture. When the user aims to search the characters by the pictures, the first search result is the character data corresponding to the frequent pictures. When the user aims to search the form by the graph, the first search result is the form data corresponding to the frequent graph. When the user aims to search for the voice by the picture, the first retrieval result is the voice data corresponding to the frequent picture. When the user aims to search the files by pictures, the first search result is the file data corresponding to the frequent pictures. Of course, different data may be used, and the data type of the specific first search result may be defined according to the specific usage scenario and the usage purpose.
After determining that the frequently retrieved picture is taken as the first retrieval target, the frequently retrieved picture can be sent to the server. After the server receives the frequently retrieved pictures, the server can search the related picture data corresponding to the frequently retrieved pictures from the massive picture data in the server database. The server returns the related picture data to the retrieval system, and the retrieval system can obtain a first retrieval result.
More specifically, after the first search result is obtained, the first search result may be sent to a receiving end, such as a user mobile phone, a computer, and the like, and then displayed to the user, so that the user can process or analyze the first search result conveniently.
In the embodiment, the picture to be retrieved is obtained; judging whether the retrieval times of the picture to be retrieved meet a preset retrieval time threshold or not; if the retrieval times meet a preset retrieval time threshold, determining that the picture to be retrieved is a frequently retrieved picture, and storing the picture to be retrieved into a preset first storage space, wherein the preset first storage space is used for storing the frequently retrieved picture for a long time; and searching by taking the frequently searched pictures as a first search target, and returning a first search result. Therefore, whether the picture to be retrieved is the frequently retrieved picture can be judged, the frequently retrieved picture is stored in the preset first storage space, and the frequently retrieved picture can be directly acquired from the preset first storage space and retrieved on the basis of the frequently retrieved picture when the picture is retrieved next time. Even if office equipment or places are changed, when the picture is frequently searched, the local picture does not need to be copied, the picture does not need to be uploaded to a cloud backup, and the picture does not need to be copied from the local or downloaded from the cloud for searching, so that the searching efficiency of the searching system is improved.
Optionally, referring to fig. 3, fig. 3 is a flowchart of another picture retrieval method provided in an embodiment of the present invention, and on the basis of fig. 1, after step 102, the method further includes the steps of:
And the preset second storage space is used for automatically and temporarily storing the temporary retrieval pictures. The step of storing the picture to be retrieved, the retrieval frequency of which does not meet the preset retrieval frequency threshold value, in the preset second storage space is a step (default execution step) automatically performed by the system, and the new picture which is not decelerated can be stored in the preset second storage space. And a time threshold value can be preset, and when the time length of the picture to be retrieved stored in the preset second storage space exceeds the preset time threshold value and is not transferred to the preset first storage space, the picture to be retrieved can be automatically deleted from the preset second storage space. Thus, the occupied space of the preset second storage space can be reduced.
And step 302, taking the temporary retrieval picture as a second retrieval target to perform retrieval so as to obtain a second retrieval result.
The temporary retrieval picture is a picture (new picture) retrieved by the user for the first time or a picture of which the retrieval times does not meet a preset retrieval time threshold value. The second retrieval target is also a target picture which needs to be retrieved by the user. The second search result is result data collected according to a second search target. The second search result may be picture data, text data, table data, voice data, archive data, or the like.
Specifically, when the retrieval frequency of the picture to be retrieved is smaller than the preset retrieval frequency threshold, it indicates that the picture to be retrieved may be retrieved for the first time, or the retrieval frequency of the picture to be retrieved does not reach the preset retrieval frequency threshold. I.e. the picture to be retrieved is not retrieved often. The second search result is also related data obtained based on the temporary search picture.
When the user aims to search the picture, the second search result is the picture data corresponding to the temporary picture. When the user aims to search the characters by the pictures, the second search result is the character data corresponding to the temporary pictures. When the user aims to search the form by the picture, the second search result is the form data corresponding to the temporary picture. When the user aims to search for the voice by the picture, the second search result is the voice data corresponding to the temporary picture. When the user aims to search the files by the pictures, the second search result is the file data corresponding to the temporary pictures. Of course, different data may be used, and the data type of the specific second search result may be defined according to the specific usage scenario and the usage purpose.
More specifically, after the second search result is obtained, the second search result may be sent to a receiving end, such as a user mobile phone, a computer, and the like, and then displayed to the user, so that the user can process or analyze the second search result conveniently.
It should be noted that, if the picture to be retrieved is not retrieved again after being retrieved last time in the same preset time period, or the retrieved number of times does not reach the preset retrieval number threshold, the retrieval record of the picture to be retrieved may be deleted. After a preset time period, if the picture to be retrieved is retrieved again, the picture to be retrieved needs to be retrieved again, and the retrieval record of the picture to be retrieved needs to be recorded again, and the retrieval frequency also needs to be recalculated. In the process, before the retrieval times of the picture to be retrieved meet the preset retrieval time threshold, the picture to be retrieved is stored in the preset second storage space.
In this embodiment, it is not necessary to store the picture that is not frequently retrieved (the temporarily retrieved picture) into the preset first storage space, so as to reduce the space occupied by the preset first storage space. Meanwhile, the temporary retrieval picture can be retrieved, and a retrieval result corresponding to the temporary retrieval picture is obtained. Therefore, not only the frequently searched pictures which are searched frequently can be searched, but also the temporarily searched pictures which are not searched frequently can be searched, so as to obtain the corresponding search result. Thereby improving the retrieval efficiency of the retrieval system.
Optionally, referring to fig. 4, fig. 4 is a flowchart of another image retrieval method provided in an embodiment of the present invention, and on the basis of fig. 3, after step 101, the method further includes:
Step 104 comprises:
and step 402, retrieving by taking the picture characteristics and the picture ID of the frequently retrieved pictures as a first retrieval target to obtain a corresponding first retrieval result, and returning the first retrieval result.
And/or, step 302 comprises:
and step 403, retrieving by using the picture characteristics and the picture ID of the temporary retrieved picture as a second retrieval target to obtain a corresponding second retrieval result, and returning the second retrieval result.
The structured data can be obtained by carrying out structured processing on the picture to be retrieved through a preset picture model. The picture features include picture feature values, for example, when the picture to be retrieved is a face picture, the picture features are face features, and the picture feature values are face feature values. The face features can be obtained by performing structural processing on the face picture through a face feature model and the like.
Specifically, after the picture to be retrieved is obtained, the picture to be retrieved can be extracted and subjected to structural processing according to a preset picture model to obtain corresponding picture features and a picture ID. When the picture to be retrieved is a frequently retrieved picture, the corresponding related picture data can be searched according to the picture characteristics of the frequently retrieved picture and the picture ID, and the searched related picture data is used as a first retrieval result to obtain a first retrieval result. Of course, when the picture to be retrieved is the temporary retrieved picture, the corresponding related picture data temporarily stored in the database can be searched according to the picture characteristics of the temporary retrieved picture and the picture ID picture. And the searched related picture data is used as a second retrieval result, and the second retrieval result is returned.
Optionally, referring to fig. 5, fig. 5 is a flowchart of another picture retrieval method provided in the embodiment of the present invention, as shown in fig. 5, on the basis of fig. 3, after step 102, the method further includes:
Step 502, if an operation instruction is received, determining the picture to be retrieved as a frequently retrieved picture, and storing the frequently retrieved picture in a preset first storage space.
The operation instruction is used for forcibly storing the picture to be retrieved, the retrieval frequency of which does not meet the preset retrieval frequency threshold value, into a preset first storage space so as to form a frequently retrieved picture. The operation instruction is triggered by the user in the retrieval system, and can be triggered by a page or a desktop in the retrieval system.
Specifically, after a picture to be retrieved is acquired, if a user determines that the picture to be retrieved is often retrieved at a later stage, an operation instruction can be triggered to force the picture to be retrieved to be stored in a preset first storage space, so as to form a frequently retrieved picture, so that when the user retrieves the picture to be retrieved again, the picture can be found directly in the preset first storage space and retrieved.
In this embodiment, when the user is determined to be a picture which is frequently retrieved, the picture can be forced to be a frequently retrieved picture, so that the retrieval frequency of the picture to be retrieved does not need to be compared with a preset retrieval frequency threshold value in the subsequent retrieval, and the picture does not need to be stored in a preset second storage space, so that the picture is prevented from being cleared. The picture retrieval is more convenient, and the retrieval efficiency of the retrieval system is improved.
Optionally, referring to fig. 6, fig. 6 is a flowchart of another picture retrieval method provided in the embodiment of the present invention, and after 101, the method further includes:
And step 602, if yes, returning to the step of executing the retrieval with the frequently retrieved pictures as the first retrieval target and returning to the first retrieval result.
Specifically, after a picture to be retrieved is acquired, whether the picture to be retrieved is a frequently retrieved picture can be determined by detecting the storage position of the picture to be retrieved. If the storage location of the picture to be retrieved is the preset first storage space, it indicates that the picture to be retrieved is a frequent retrieval picture, step 104 is executed, and then the process of retrieving by using the frequent retrieval picture can be quickly realized, so as to improve the retrieval efficiency. Of course, if it is detected that the storage location of the picture to be retrieved is the preset second storage space or other storage spaces, it is determined that the picture is not frequently retrieved.
