Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments of the present disclosure, shall fall within the scope of protection of the present application.

In the prior art, the efficiency and experience of the client side when acquiring the pictures from the content server side can be improved by adopting a new picture format to transmit and process the pictures.

However, the inventor finds in practical application that, on one hand, in a client, many picture application scenes often only need a key area (i.e., an interest area) that a user focuses on in a picture, rather than all pictures, for example, in a live broadcast application, fan pays more attention to a face part in the picture, on the other hand, the client also has many layout restrictions when displaying the picture, and layout restrictions of different clients are different, and at this time, adjustment (for example, clipping and zooming) operations need to be performed on the obtained picture before displaying, but after the adjustment operations, the picture display effect is often not ideal, for example, the picture is deformed after zooming, and for example, part of the content is lost due to improper clipping of the picture. Therefore, how to enable the client of the user to effectively obtain the picture content focused by the user is an urgent problem to be solved in the picture application.

Based on the above, the inventor provides a method, a device and equipment for inputting and accessing pictures. In the picture inputting scheme, the overall thought shown in fig. 1 can be adopted, after the picture to be input is obtained, the key area, namely the interest area, concerned by the user in the picture to be input is identified, so that the area information of the interest area in the picture is determined, and the mapping data corresponding to the picture to be input is generated, so that the picture to be input can be stored (i.e. input) into the storage system according to the mapping data. Therefore, in the subsequent access of the picture, the interest region in the picture can be directly accessed according to the mapping data, and the non-interest region in the picture is ignored, so that the subsequent processing of the interest region is facilitated, and the application efficiency and the user experience of the picture can be improved.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

An embodiment of the present specification provides a picture entry method, as shown in fig. 2, which may include:

and S102, acquiring a picture to be recorded.

The picture to be recorded is a picture related to an application scene, for example, in a live scene, the picture to be recorded may be a picture in live broadcasting.

In a specific implementation, the picture to be recorded can be obtained from a picture library, a video stream, and other resources containing the picture to be recorded, and a description thereof is omitted here.

In an embodiment, in order to obtain the picture to be input, the picture to be input may be further uploaded to a pre-specified file library to be processed in advance, where the file library to be processed may include a database for storing files, and the database may be a distributed database or a centralized database, which is not limited specifically here. Therefore, the picture to be recorded can be obtained from the file library to be processed.

And S104, detecting the interest area in the picture to be recorded.

The interest area includes a part of the picture to be entered, which is focused by the user, and the value of the part is often regarded as the largest part in the picture in a picture application scene, for example, in a picture application that needs to highlight the facial expression of a person in the picture, a face part belongs to the interest area in the picture.

In a specific implementation, detecting the interest region may be performed by detecting whether the image includes the interest region, and then one or more of a square, a circle, an ellipse, an irregular polygon, and the like may be adopted to outline the interest region, so as to facilitate subsequent processing of the interest region.

In a specific implementation, the method for detecting the interest region may be selected according to an actual application scenario, for example, the position of the interest region in the picture is known, and at this time, the interest region may be directly detected according to known position information, and for example, the position of the interest region in the picture is unknown, and at this time, the detection needs to be performed according to the feature of an interest target, for example, the interest target is a human face, and at this time, the interest regions in the picture may be detected one by using a human face model, which is not described herein.

And S106, determining the area information of the interest area in the picture to be recorded.

The region information is used to represent information of a region to which the region of interest belongs in the picture to be recorded, and at this time, the region information may include one or more of position information of the region of interest in the picture to be recorded, a shape and a size of the region of interest, and a number of the region of interest.

And S108, generating mapping data of the interest region in the picture to be recorded according to the region information according to a preset generation strategy.

The mapping data comprises path information used for accessing the interest area in the picture to be recorded after the picture to be recorded is recorded, for example, the mapping data is a file name (namely the path name of the position where the picture to be recorded is located) corresponding to the recorded picture, and the file name comprises the area information of the interest area, so that the interest area can be directly accessed according to the file name; the generation policy may be preset according to an access path required for accessing the picture to be recorded, which is recorded in the storage system in practical application, for example, in the foregoing example, the access path information is a file name, and the generation rule is a generation rule of the file name, which is not described here one by one.

And S110, inputting the picture to be input into a storage system according to the mapping data.

The storage system may include a database, and the form of the database is not limited in the present application.

Through the steps S102 to S110, after the interest region in the picture to be recorded is detected, the region information of the interest region in the picture to be recorded is further determined, so that mapping data of the interest region in the picture to be recorded is generated according to the region information, and the picture to be recorded is recorded into the storage system according to the mapping data. Therefore, in the subsequent processing, the interest region in the picture to be recorded can be accessed directly according to the mapping data, the non-interest region in the picture can be ignored, and further, in the subsequent processing, the interest region can be effectively processed, so that the application efficiency and the user experience of the picture can be improved.

In one embodiment, the object (i.e. the object of interest) focused by the user may be predetermined according to the actual application scene, so as to quickly detect the interest region corresponding to the object of interest in the picture to be recorded according to the characteristics of the object of interest.

In one embodiment, the importance degrees of different interest objects in the picture can be divided according to the attention degree of the user to the interest objects, and then the interest region corresponding to the interest object with the highest importance degree is preferentially detected according to the importance degrees, so that the most concerned part of the user is preferentially processed, and other interest objects with low importance degrees can be ignored; and when the object of interest with the highest importance degree does not exist, detecting the interest area of the object of interest with the lower importance degree. Therefore, the interest areas with different attention degrees in the picture can be processed in a targeted manner, and the pertinence and the efficiency of processing can be improved.

Specifically, the step S104, namely, the detecting the region of interest in the picture to be recorded may include:

detecting whether a face area exists in the picture to be input;

when the face area exists in the picture to be recorded, taking the face area as an interest area;

when the face area does not exist in the picture to be recorded, detecting whether a preset target area exists in the picture to be recorded;

when the preset target area exists in the picture to be recorded, taking the preset target area as an interest area;

and when the preset target area does not exist in the picture to be recorded, taking the whole area of the picture to be recorded as an interest area.

For example, in an application scenario, the interest region may include a face region and a predetermined other important region (i.e., a predetermined target region), where the attention level of the face region is the highest, and the predetermined other target region is the next, at this time, the face region corresponding to the face may be detected first, and when the face does not exist in the picture, the other important region in the picture may be detected, and if the predetermined other important region does not exist in the picture, the whole picture is determined as the interest region by default.

In one embodiment, in order to facilitate accessing the region of interest in the picture to be recorded according to the mapping data, a file name may be used as the mapping data, that is, a file name used when the picture to be recorded is stored in the system is generated according to the region information of the region of interest. Specifically, the generating a policy includes a file name generating policy, and generating mapping data between the region information and the picture to be input according to a preset generating policy includes: generating a strategy according to a preset file name, and adding the region information into the file name of the picture to be recorded; and taking the file name of the picture to be input added with the area information as mapping data corresponding to the picture to be input.

In a specific implementation, the file name generation policy may be preset according to actual needs.

An application example is given here, and specifically, when information of a picture to be entered is added to a file name and a new file name is generated, an example of an encoding rule that can be adopted is as follows: type _ value, where type is used to identify the type (i.e., category) represented by the information, and can be predefined or extensible, and value is used to identify the value represented by the information.

For example, the original file name of the picture to be recorded is abcdefg.

When detecting related information (such as an interest region) in a picture to be input, and determining region information of the interest region, wherein the interest region is a face region, the region information includes position information of the face region and the number of faces, at this time, the region information of the face region is in a file name, type can identify the face, value can identify the region information, the position information of the face region is a long and wide region (length is 300, width is 80) starting from coordinates (200 ) at the upper left corner of the picture, and the number of faces is 2, at this time, a new file name generated by adopting the above coding method is adopted, and the result can be as follows:

abcdefg_r_1600x900_s_122098_f_x200y200w300h80c2.jpg。

wherein r _1600x900 represents that type is r (resolution), value is 1600x900, and represents that the resolution of the picture to be recorded is 1600x 900; similarly, s _122098 indicates that the file size (size) of the picture to be recorded is 122098 bytes, f identifies a face (face), x200y200w300h80c2 identifies a face region, which is a region with the start coordinate (x being 200 and y being 200) and the length and width being 300 × 80, wherein c2 identifies that the count value of the face is 2.

By encoding the related information of the picture to be input, such as the region information, into the file name in the subsequent input system, the picture to be input and the interest region in the picture to be input can be accessed according to the file name, and the general view of the region information corresponding to the interest region can be obtained from the file name.

In one embodiment, a uniform resource locator may also be employed as a representation of the mapping data. Specifically, the generating a policy includes a uniform resource locator generating policy, and generating mapping data corresponding to the to-be-input picture according to the region information according to a preset generating policy includes: generating a strategy according to a preset uniform resource locator, and adding the region information into the uniform resource locator corresponding to the picture to be input; and taking the uniform resource locator corresponding to the picture to be input added with the area information as mapping data corresponding to the picture to be input.

In specific implementation, the uniform resource locator generation policy may be preset according to actual application, and the specific encoding manner and encoding process may also be preset according to application.

It should be noted that, in the specific process of using the representation form of the uniform resource locator, except that the name of the uniform resource locator after encoding needs to meet the relevant requirements of the uniform resource locator, other encoding processes may refer to the above-mentioned relevant description of using the representation form of the file name, and are not described herein again.

In an embodiment, the mapping data may be further stored in an access information stream of the picture, so that the client acquires region information of a region of interest in the picture from the information stream, and further determines the display layout according to the region information. For example, the aforementioned file name and/or uniform resource locator is put into the access information stream corresponding to the picture, where the access information stream includes information for accessing the picture.

For ease of understanding, an example illustration of a picture entry method incorporating a filename and a uniform resource locator as representations of the mapping data is given herein.

In an assumed example, the attention degree of a face region is the highest in an interest region in a picture to be recorded, the preset target region is the second order, the attention degree of the whole picture to be recorded is the lowest, a file name containing region information is used as the file name of the picture to be recorded in a storage system, and after recording, a uniform resource locator for accessing the picture to be recorded is generated, so that the picture to be recorded can be accessed by directly using the uniform resource locator during accessing.

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the embodiments of the apparatus, the device, and the nonvolatile computer storage medium, since they are substantially similar to the embodiments of the method, the description is simple, and for the relevant points, reference may be made to the partial description of the embodiments of the method.

The apparatus, the device, the nonvolatile computer storage medium, and the method provided in the embodiments of the present specification correspond to each other, and therefore, the apparatus, the device, and the nonvolatile computer storage medium also have advantageous technical effects similar to those of the corresponding method.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardbylangue (Hardware Description Language), vhjhdul, and vhigh-Language, which are currently used in most general. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functionality of the units may be implemented in one or more software and/or hardware when implementing the present application.

As will be appreciated by one skilled in the art, embodiments of the present invention may be provided as a method, system, or computer program product. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, the present invention may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and the like) having computer-usable program code embodied therein.

The present invention is described with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.

These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.

The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.

Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device. As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.

It should also be noted that 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. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.

The application may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The application may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.
